WHAT IS AN
EXPANSION JOINT?
There are other terms in use for
expansion joints such as expansion
bellows, flexible joints and
compensators.
A typical expansion joint is comprised
of one or more metal bellows (most
commonly stainless steel) or from
materials such as rubber, fabric or
plastic such as PTFE. While materials
such as rubber, plastic and fabric
have their limitations, metal is the
most versatile of all materials. Metals
are suitable for use at high tempera-
tures, have high strength properties
and are resistant to corrosion.
Metallic expansion joints are designed
to safely absorb the dimensional
changes of steel pipe systems and
ducts. The changes could be
heat-induced expansion and
contraction, vibrations caused by
rotating machinery, pressure
deformations, misalignment during
installation or building settlements.
The main element of the expansion
joints is the bellow. The bellows are
made up of a series of convolutions,
with the shape of the convolution
designed to withstand the internal
pressure of the system, but flexible
enough to accept axial, lateral and
angular deflections.
Expansion joints are considered as
very important components of a
complete pipe system and are widely
used particularly in industries where
thermal expansion in pipe systems
occur. Expansion joints also offer the
advantage of reducing stresses in
pipe systems generated by thermal
expansion, and reduce pipe loads at
connections to sensitive equipment
such as pumps and steam turbines.
Taken together this acts to prolong
the service life of pipe systems, and
reduces the risk of their downtime for
additional maintenance and repair.
Engineers and pipe designers
routinely incorporate expansion joints
into their pipe systems, as expansion
joints add flexibility in to the design
and reduce costs through removing
the complexity of fix points, guides
and reduces the overall space
requirements for the pipe system.
Further expansion joints are more
effective than alternatives such as
pipe bends and pipe loops due to
Steel expansion joints are important
components in many industries and
are used extensively in among others:
l Energy sector (power plants,
nuclear power plants, district
heating pipe systems etc.)
l Steel plants
APPLICATIONS
l Petrochemical industry
(oil refineries, pumping stations,
oil rigs etc.)
l Chemical industries (asphalt
manufacturers etc.)
l Process industry (sugar
factories etc.)
l Exhaust systems and engines
l Pulp and paper industries
l LNG/LPG tankers, -carriers etc.
Expansion joints are often installed
near boilers, heat exchangers,
pumps, turbines, condensers,
engines and in long pipe systems
or pipe ducts.
their greater ability to conserve space,
their economic efficiency and better
performance in absorbing larger
movements.
Advantages
l Simple in design and function
l Space reduction
l Weight reduction
l Cost reduction
l Reduces engineering and design
complexity to piping systems
l Better flexibility for piping layout
l Reliable and proven in the field
Expansion joint types
Expansion joints come in a wide
variety of designs. Some of them are
standard and some are customised
as per client requirements. Although
their design may vary significantly, all
expansion joints are nevertheless
composed from some of the following
components, all with one or more
specific functionalities:
bellows, welding ends, flanges,
hinges, tie-rods, spherical washers,
wire mesh, insulation, inner sleeve,
external cover, elbow and/or ring
reinforcement/equalizing rings.

EXPANSION JOINTS VS.
ALTERNATIVE FLEXIBLE SOLUTIONS
For the absorption of movements in
pipe systems, the pipe designer can
choose between the installation of
expansion joints, or other flexible
solutions such as a pipe loop. Pipe
loops also allow movements of the
pipe system, but only in the axial
direction of the pipe system.
Pipe loops require more material such
as pipe bends, pipe support,
insulation and NDT. Furthermore, pipe
loops consume a lot more space and
can generate a greater pressure loss.
Due to this, the installation of
expansion joints is considered as a
reliable and cost effective alternative
to the use of pipe loops.
The use of expansion joints ensures
less material consumption, greater
space savings with the reduced
number and complexity of fix points
and guides. Further, it requires less
labour inputs such as those for
welding and NDT. Additionally, the
selection of expansion joints
eliminates the bending stresses in
the pipe system, which could cause
a fatigue crack of the pipe system.
The appropriate type can absorb
movement in several planes and is
maintenance free. Further,
a replacement of a worn-out unit is
easier and more efficient in terms of
downtime and costs, than replacing
a complete pipe loop.
Inverse pipe loops require strong fix
points, which can obtain the full
pressure thrust force.

Pressure loss
The pressure loss is significantly lower
when installing an expansion joint
rather than a pipe loop.
The advantage of expansion joints
versus pipe loops, increases with
larger pipe sizes (DN) and increased
pipe thicknesses, which is further
explained in the table below.
In this table, an expansion joint is
compared against a pipe loop.
The table shows that a DN 100
expansion joint is in general approxi-
mately 37% cheaper than a pipe loop
of the same size. If the pipe size is
DN 400, an expansion joint solution is
approximately 82% cheaper than a
pipe loop.

these conditions: PN 10, EN 1.0038/

expansion -0/+ 50 mm.

The price index is based on material
and working hours. Areas marked
with * are not part of this price index.
Please note that both solutions will
have extra costs such as extra costs
for supports/guides for pipe loop and
for stronger fix points for expansion
joint respectively.

MOVEMENTS
Axial movement
Axial movement is movement of the
bellows in the direction of the
longitudinal axis.
This movement can be compressive,
where the bellows shortens in length,
or extensive where the bellows
extends in length.
In the majority of applications, the
expansion joint is deemed necessary
because of the increasing tempera-
ture of the pipe system. The expan-
sion joint is fitted in pipe systems and
installed between two fix points
(anchors).
The extension of the pipe is compen-
sated by the compression of the
bellows.
In some cases, typically cryogenic
and chilled water services, the pipe
system contracts in service causing
the expansion joint to extend in
length.
Thermal expansion of the pipe system
results in an axial compression of the
installed expansion joints.
The specifications for expansion joints
should always state the movements
as they affect the expansion joints,
and not those generated by the pipe
system.
Lateral movement
Lateral movement is movement
perpendicular to the bellow's
longitudinal axis; it is a shearing
movement of the bellows with one
end offset from the other, usually with
the ends of the bellows remaining
parallel to each other.
A single bellow expansion joint,
working with a shearing action, can
accept a relatively limited amount of
lateral movement, especially when the
flow characteristics of the system
demand that an inner sleeve is
necessary. For larger lateral move-
ment capability, it is usual to utilise a
twin bellows arrangement with an
intermediate pipe between the
bellows, the expansion joint lateral
movement is taken up by an angular
rotation of the bellows in opposite
directions.
The amount of lateral movement
available depends on the rotational
movement capacity of each bellows
and the distance between them,
increasing the distance between the
bellows increases the lateral move-
ment capability of the expansion joint
proportionally.
Lateral movement can be applied in
more than one plane; in such cases it
is important that the expansion joint
designer is made aware of the total
lateral movement to be applied.
Angular movement
Angular movement is the rotation of
the bellow's longitudinal axis at one
end relative to the other, the axis of
rotation is taken at exactly the
midpoint of the bellow and
perpendicular to the longitudinal axis.
Expansion joints using angular
movement to control pipe system
expansion are almost always used in
pairs, sometimes combined as part of
a twin bellows unit and sometimes in
sets of 2 or 3 in pinned restrained
expansion joints.
The intelligent use of the angular
capability of the bellows can enable a
large amount of movement to be
absorbed. In particular, pinned units
used in 2-pin or 3-pin arrangements
can convert pipe growth into angular
rotation and control the expansion
from 2 directions and in 2 planes.
It is important not to confuse angular
rotation with torsion. Torsion is a
twisting rotational movement around
the longitudinal axis; it generates
undesirable shear forces within the
bellows and its influence on the
bellows should always be avoided.
Please refer to the section about
torsion.
Universal movement
Universal expansion joints can be
designed and built to absorb applied
axial, lateral and angular movements
simultaneously. Such units usually
require a lot of flexibility to absorb
significant amounts of movements in
combination. However, this often
leads to a limited pressure containing
capacity due to considerations
towards the bellows’ stability.
Important
It is important that the designer of
expansion joint is fully informed of all
the movements to that the expansion
joint will encounter. Knowledge of the
amount of movement, its direction
and any combination of axial, lateral
and angular movements occurring
together is essential for the correct
design of the expansion joints.

AXIAL
EXPANSION JOINTS
Application
Having the ability to compensate for
axial movements and with its simple
and compact overall dimensions, axial
expansion joints are very widely used
within a range of applications.
They are especially common in long
pipe runs, examples of which would
include exhaust systems, ventilation
and flue gas systems, district heating,
steam, oil and gas pipe systems.
Axial movement
Axial movement is considered as an
elongation or compression of the pipe
system in its longitudinal axis,
meaning that in the process of
absorbing the movements, the overall
length of the expansion joint will either
extend or compress.
Axial expansion joints which are
designed to absorb large movements,
can contain one, two or several
bellows in one unit, and larger move-
ments can also be achieved by
pre-tensioning or by installing several
expansion joints on the pipe section.
Depending on the nominal diameter
and length, axial expansion joints have
the ability to absorb minor
lateral and angular deflections and
installation tolerances. However, we
recommend the utilisation should be
limited to its main function, otherwise
its service life may be negatively
impaired.
Where there is a need for absorption
other than that of axial movements,
we strongly recommend alternative
options and Belman will be pleased to
provide its professional advice.
Definitions
Axial movement is shown as AX and
stated in mm. Compression and
elongation is indicated as
negative (-) and positive (+).
Example
Elongation +10 and compression -20
will be shown as: AX +10/-20 mm.
Equal longitudinal movements are
shown as: AX +/-20 mm (2δN).
l Simple solution for compensation
of temperature fluctuations
l No change in the flow direction
l Compact and space saving
solution
l Relatively low cost
l Strong fix points and good guides
are required
l Large movements require
utilisation of several axial
expansion joints
l Many fix points and guides are
needed for long pipe sections
l Higher costs for fix points and
guides
ADVANTAGES REQUIREMENTS
Axial expansion joints are designed to
absorb axial movements (extension
and compression in its longitudinal
axial direction). The thermal expansion
of a straight pipe line section between
two fix points can be absorbed by
axial expansion joints with a relatively
compact build-in length. This offers a
simple and cost efficient solution in
terms of movement compensation.
Axial expansion joints can be
equipped with all kinds of connectors,
such as welding ends or welded or
loose (rotatable) flanges.

27
LATERAL
EXPANSION JOINTS
number of end connections like
welding ends, flanges and/or a
combination thereof. Additionally,
it can be equipped with accessories
like: inner sleeves, covers,
intermediate pipe and tie rods.
The type of expansion joint selected
depends on both its cost effectiveness
and its suitability for the function to be
fulfilled. The economic
consideration should not only take into
account the cost of the expansion
joints, but also the required fix points,
guides and structures.
Application
As lateral expansion joints absorb
movements in lateral directions in one
or more planes, and absorb adjusting
forces, they are widely used in more
complex pipe systems with many
different directions and levels.
Lateral expansion joints make possible
the absorption of movements which
are perpendicular to the longitudinal
direction of the pipeline, and are
therefore ideal for installation in pipe
systems with bends, Z shaped pipe
systems and in 3 hinged systems.
Lateral expansion joints can be used
as tank settlement bellows, vibration
absorbers and in all pipe systems with
bends or a change in the pipe
direction.
Lateral movement
Lateral movement is a sideways
(lateral) displacement of the ends of
the expansion joint in a direction
perpendicular to its longitudinal axis.
Lateral movement can be absorbed
both in the horizontal and the vertical
axis/direction according to the design
of the pipe system. Lateral movement
can, to a limited degree, be absorbed
by one bellow. If larger movements
are to be absorbed, we recommend
a design with a universal expansion
joint (two bellows with an intermedi-
ate pipe) absorbing the movement
and this also results in lower offset
forces.
Definitions
Lateral movement is shown as LA
and stated in mm. The parallel
displacement is indicated as
negative (-) and positive (+).
Example
The elongation of one side of the
bellow is +10 and the compression of
the other side of the bellow is -20.
This will be shown as: LA +10/-20
mm. Equal parallel displacement is
shown as: LA +/-20 mm (2λN).
l Absorbs movements in all lateral
directions
l Absorption of large lateral
movements with only one lateral
expansion joint
l Reduced loads on all fix points
as the tie rods absorb the loads
without transferring pressure thrust
on to the fix points

l For absorption of large expansions
several lateral expansion joints are
needed
Lateral expansion joints are used to
absorb lateral deflection. Lateral
expansion joints can move in all lateral
directions simultaneously for absorb-
ing expansion from two pipe sections
in different directions.
The lateral expansion joint is normally
equipped with fixtures such as
external tie rods, which allow the unit
to absorb movements in all lateral
directions but also to absorb the
pressure thrust (incl. full
vacuum).
The lateral expansion joints are
available with one or two bellows
(universal type) as well as with a

29
ANGULAR
EXPANSION JOINTS
Angular expansion joints allow angular
movements only, contrary to axial
expansion joints which elongate and
compress in the pipeline axis. The
angular expansion joint moves in an
angular rotation in one or several
planes, controlled by a pair of hinges
or a gimbal. The angular expansion
joint is as standard delivered with
either hinges or gimbals, and can be
manufactured with any end
connections such as welding ends,
welded flanges, or loose flanges or
combinations thereof, depending on
client requirements.
Hinged angular expansion joints
Hinged angular expansion joints are
equipped with hinges, to absorb
angular movement/rotation in one
plane only. The hinges are designed to
resist the pressure thrust from the pipe
system. Single hinged expansion joints
are generally used in pairs or threes
with a connecting pipe system
between, and widely used in irregular
and complex pipe systems.
Gimbal angular expansion joints
Gimbal angular expansion joints are
designed to absorb angular
movements in several planes without
transferring pressure thrust on to the
fixed points. A gimbal expansion joint is
more flexible than a hinged expansion
joint as the gimbal enables multiple
angular rotations.
Angular expansion joints in general
Angular expansion joints offer a wide
range of options, and when built into
two or three pinned pipe systems, they
can accommodate very large
movements with very low reaction
forces, without the need for fix points
and structures.
As angular expansion joints are fully
restrained, they require only
inexpensive guides or intermediate
guides. This gives an economic
advantage in large diameter, hot piping
systems, even if the movements are
complex and in several planes. Further,
the hinges or gimbal can be designed
to support the dead weight loads from
the adjacent pipes and connected
equipment, and to carry wind loads,
snow loads, and any other external
loads from the pipe system, minimizing
the need for fix points and structures.
The hinge can also be designed to
eliminate torsion forces acting on the
bellow. The bellow does not allow any
torsion, and this should be

ANGULAR
EXPANSION JOINTS
l Absorbs angular movements in
single or multi plane
l Use of normal guides
l Reduced loads on all fix points
l Changes in flow direction/pipe
direction is required
l More space consuming than axial
expansion joints
l Two or three expansion joints are
required for a system
counteracted against in all cases.
When the angular expansion joints are
installed in two hinged or three hinged
systems, the distance/intermediate
pipe between each unit should be as
large as possible, as this allow
maximum lateral deflection or
movement to be absorbed. If the
thermal growth of the intermediate
pipe is significant, a three hinged
system is required.
Angular movement
Angular movement is an angular/
rotational displacement of the
expansion joint where its longitudinal
axis is displaced as an arc from its
initial position. This is to be under-
stood as an angulation of the
expansion joints two end planes
relative to each other, which results in
the longitudinal centreline becoming
an arc, like a pipe bend.
The convolutions are uniformly
compressed along the inside of the
bellows longitudinal centreline, and
uniformly elongated along the outer
radius of the arc.
Torsion or twisting of one end with
respect to the other end about its
longitudinal axis, and is not to be
understood as angular rotation.
Definitions
Angular movement is shown as AN
and stated in degrees. Angular
rotation is indicated as negative (-)
and positive (+) respectively.
Example
Angular movement positive +5 and
negative -10 will be stated as: AN
+5/-10°. An equal angular rotation
over the bellows longitudinal centre-
line are stated as AN +/-10° (2αN).

UNIVERSAL
EXPANSION JOINTS
l Absorbs movements in all
directions
l Absorption of large axial
movements and lateral move-
ments in one expansion joint
l Can be modified to suit existing
installation gap
l Only for low pressure applications
l Fix points and good guides are
required
Universal expansion joints consist of
two multi-convoluted bellows
connected with an intermediate pipe
into one assembly.
Belman has developed a series of
universal expansion joints that allows
all three movements: axial, lateral and
angular simultaneously. The universal
expansion joints can be equipped with
all kinds of end connections, like
welding ends, welded or loose
flanges, and an endless number of
accessories such as inner sleeves,
cover and movement controls.
Universal expansion joints featured in
this catalogue are restricted to the
maximum design pressure of 2,5
BarG, but as customised solution they
can be designed for higher pressure.
The universal expansion joints allow a
large amount of lateral offset in
multiple planes, and the lateral
deflection can be increased or
decreased by changing the length of
the intermediate pipe.
Universal expansion joints do not use
tie rods, and are therefore suitable
only for low pressure applications. Fix
points and guides must be sufficiently
designed to withstand the full pressure
thrust forces and other loads. An
universal expansion joint is not to be
confused with a lateral expansion joint.
Application
Universal expansion joints can absorb
movements in all directions, and are
used in uncritical, low pressure
installations like ventilation ducts,
exhaust gas systems, fresh air
ventilation and process equipment.
Definitions
Movement is shown as AX (axial),
LA (lateral), AN (angular) mm + deg.
The parallel displacement is indicated
as negative (-) and positive (+)
respectively. It is very important to
notice if the movements is stated in
combination (universal), or as an
alternatively combination of the
different directions.
Example
The elongation of the bellow is +10
and the compression of the bellow is
-20. This will be shown as: +10/-20
mm. Equal parallel displacement is
shown as: +/-20 mm.

35
EXHAUST
EXPANSION JOINTS
Exhaust expansion joints are
designed to absorb heat induced
expansion and contraction of pipe
systems and exhaust systems.
Belman has developed a wide range
of exhaust expansion joints, which are
designed to give high movement
absorption with low spring rates for
best overall performance.
The typical pressure rating for exhaust
expansion joints, temperature
depending is 1.0 BarG.
These units are available with many
end fitting options including welding
ends, flanges (welded and loose). For
smaller sizes, it is often possible to
slide the bellows tangent over the
l Gas-tight and resistant to
corrosion and temperature
l Absorb vibrations and oscillations
l Light weight, reducing loads on
hangers and pipe supports
l Very low spring rates, and high
flexible performance reduces loads
on hangers and pipe supports
l Economical
l High flow velocity often requires an
inner sleeve
l Exhaust bellows exposed to
vibration should be designed to
ensure that the natural frequency
and any harmonics do not
coincide with the frequencies of
the exhaust system
exhaust pipe and secure using band
clamps or worm-drive clips.
Exhaust expansion joints can absorb
axial and lateral movements alone or
in combination, and it is usually the
required movement capacity which
determines the selected configuration.
A single bellow is normally selected to
accept mainly axial movement
although some lateral movement is
usually possible. Where the amount of
axial movement is outside of the
capacity of a single bellows, a double
expansion joint may be necessary.
When the unit is required to accept a
significant amount of lateral
movement, including applications
where axial movement is applied
simultaneously, a double bellows is
usually the preferred option.
A double bellows unit has a interme-
diate pipe between the bellows and
sometimes this is an integral part of
the bellows tube reducing the need
for welded joints.
Belman exhaust expansion joints are
designed to be as light as practically
possible to give minimum loads on
hangers and pipe supports. Further,
the bellows technology, often
incorporates multi layers, giving
maximum movement and flexibility
(for minimum deflection forces and
good fatigue properties) with good
performance in conditions where
vibration prevails.
Exhaust expansion joints are generally
unrestrained so the pressure force
(generated by the bellows when
pressurised), together with the
deflection forces resulting from
movement, must be contained by the
system fix points and guides.
At high temperatures or where the
flow velocity is high, Belman always
recommends an inner sleeve in the
bellows. The inner sleeve protects the
bellows against abrasion from any
particulate matter in the flow medium
and helps to smooth the gas flow
over the convolutions which helps in
the reduction of turbulence. It can
also help to reduce the temperature
of the bellows in the expansion joint.
Application
Exhaust expansion joints are used in
a wide range of applications including
gas turbine exhausts, power units,
generator sets, marine propulsion
systems, OEM engines and auxiliary
systems.
Customised expansion joints can be
designed and built for any specific
requirement and application.

OUR ACCREDITATIONS
Welding
Our focus on quality assurance
includes also welding and within this
area, we follow both client requests,
project requests, our own
procedures, our own quality
objectives and the requirements of
the design codes.
A natural step for Belman has been
to automise the process of welding
as much as possible to ensure that
we have the right qualified welding
procedure (WPS) for the project and
also that we are using the right certi-
fied welders for the project. We hold a
database with more than 200 different
qualified WPS.

own inspectors (IWS and IWIS).
As well as we have 100% trace-
ability on all materials, we also have
full traceability on all filler materials.
3.1 certificate can be provided for all
of them. All documentation are kept in
our files for minimum 10 years, which
means that we can always find the
needed documentation for the client
in case it is required.

Material control
To ensure a short and accurate
delivery time, we have an extensive
stock of raw materials. For the bellow
material, we stock various steel types
in both sheets and coil. These are
qualities such as different types of
common stainless steel, all 300 series
and special alloys being Inconel,
Incoloy, Hastelloy, titanium, nickel etc.
As quality is important to us and to
our customers, we have compre-
hensive control at goods reception.
We check all incoming raw materials
according to our QA procedures
and policies and that means, among
others, that we check the material
thickness, certificates, marking of the
steel, if the goods are as ordered etc.
We have a quarantine stock for goods
not approved by the inspector.
To ensure a consistent quality on our
subsupplies and raw materials, we
audit our suppliers and we set also
high demands for them in terms of
having the same approvals, proce-
dures and experience as we do.
3.1 certificates is a must and we are
certified to mark transfer when the
sheet and coil are used for several
orders.
Selection of the suitable material for
the expansion joint that suits the
project/application is crucial. To
ensure this with considerations of
all applicable norms and standards,
we have build an extensive material
database.

DOCUMENTATION
Not only does Belman concentrate on
the quality and finish of its products,
the same careful attention is also
applied to the associated
documentation.
Belman has developed its own
special software which manages the
material traceability on each project.
It is also integrated with our design
software to ensure the integrity of all
materials used against the design
code. Documentation is provided
with every project. As we are able to
execute tests and inspections
in-house, our documentation is
generated quickly and depending on
the client's request, documentation
can be supplied with the goods or
sent separately. This ability to quickly
generate documents ensures that no
time is lost when our products arrive
at the destination, allowing the instal-
lation to be immediately executed with
the absolute minimum of downtime.
Due to our strength in document
management, we are repeatedly
chosen by clients.
For the expansion joints specified in
this catalogue and for our
customised solutions, we can provide
the complete documentation
packages needed. Documentary
requirements are determined by the
project specifications, the applica-
tion and the customer, industry and
design code.
Some projects require just a few
certificates while other projects, such
as those for e.g. the nuclear power
industry, require thousands of pages
of documentation. No matter what
the requirements may be, Belman has
the experience to ensure compliance.
Typically, we offer our customers the
following documentation:

TEST
Our expansion joints can be subject
to any kind of tests and inspections.
The scope of tests meets the
requirements of the design code or
the customer’s specification. Some
tests are performed by Belman and
some are performed by 3rd parties.
Concerning testing, we differentiate
between two different test types:
non-destructive testing (NDT) and
destructive testing, also called
destructive physical analysis (DPA).
By testing, we verify that our
expansion joints are suitable for the
intended use. Non-destructive testing
is most commonly used, as it does
not permanently alter the tested
subject.
Non-destructive tests
l Visual test
l Leak tightness test
l Dye penetrant test
l Radiographic examination
l Hydrostatic pressure testing
l Magnetic particle examination
l Ultrasonic testing
l Positive material identification (PMI)
l Helium leak testing
l Eddy current test
l Dimensional check
Destructive tests
l Fatigue life testing
l Squirm testing
l Movement test
l Vibration test
l Burst test
l Metallurgy inspections
l Cupping test (Erichsen test)
l Hardness test
DESCRIPTION OF TESTS
Visual test
A visual inspection of the bellow
convolutions for any cracks and
irregularities, weld imperfections,
surface finish and paint imperfections.
Leak tightness test
Leak testing is used to verify
conformity of expansion joins. There
are several ways to execute a leak
test; generally the expansion joints
are pressurised with air and then
the inspected area is sprayed with a
soap-water solution. The subsequent
formation of soap bubbles would
indicate the presence of a leak.
Other types of media used for
testing could involve gas, with the
use of sensors for the detection of
gases such as helium.
Dye penetrant test
Dye penetrant test is a widely used
non-destructive test method to locate
cracks in a welded surface, lack of
welding fusion, leaks and fatigue
cracks. The tested surface is cleaned
and then the liquid penetrant is
applied. The penetrant liquid is
allowed 30 minutes developing time
in which to soak into any pores, flaws,
cracks and pin holes. After the devel-
oping time, any excessive penetrant
liquid is removed from the inspected
area and then a white penetrant
developer is applied that draws the
original penetrant out from defects to
form a visible indication. The
indication will appear as a red spot on
the tested surface. The dye penetrant
test is the perfect way to render a
defect, such as a visible crack.
Belman has certified dye penetrant
technicians and procedures. Dye
penetrant liquid is a rapid and cost
effective method of testing.
Radiographic examination
Radiographic examination is a
non-destructive test method, also
called X-ray. The test generates an
image by using electromagnetic
gamma rays to penetrate through an
object. The X-rays that pass through
are captured by a detector (film or
digital) that generates a superimposed
image of the tested specimen’s
internal structures.
Radiographic test is used to inspect
discontinuities and imperfection of
butt welds such as: interpass cold
lap, porosity, slag inclusion, incom-
plete penetration, incomplete fusion,
root undercut, external undercut,
offset or misalignment and cracks.
Hydrostatic pressure test
A hydrostatic pressure tests verifies
expansion joint for its strength and
leak resistance. The test pressure
is always higher than the operating
pressure to give a factor of safety.
The safety factor used is depending
on the regulations that apply. Belman
has large scale testing equipment
to perform pressure testing up to
DN 3000 and 500 tons. Belman can
pressure test in accordance with any
applicable code.
Magnetic particle examination
Magnetic particle inspection is a
non-destructive testing for detecting
discontinuities in surfaces and sub
surfaces in ferromagnetic materials
and alloys. Magnetic particle inspec-
tion (MPI) can also be used to show
indications of stress corrosion
cracking in pipe systems. Belman
offers magnetic particle examination
as an economical alternative to
radiographic testing.
Ultrasonic testing
Ultrasonic test is used to transmit
sound waves into the test
material. With a probe that sends
sound waves into the material, there
are two indications on the
oscilloscope. One is from the initial
pulse of the probe and the second
comes from the back wall echo. If
there is an imperfection in the tested
welds, this is displayed as reduced
amplitude; the depth of the defect
can also be determined. This non-de-
structive test method can be used on
carbon steel, stainless steel, alloys
and other materials. This test method
can also be used to measure the
thickness of a subject, for example in
order to determine the level of
corrosion on pipework.
Positive material identification
(PMI)
Belman offers positive material
identification on all materials used.
PMI is rapidly increasing in its use as
a non-destructive test method. By
exposing X-rays into materials, each
chemical element reflects the radia-
tion of X-rays by generating
energy in a different way.
XRF analysers can then measure
the intensity and characteristic of
the emitted energy, from which the
analyser can thereby determine the
qualitative and quantitative composi-
tion of the material being tested.
Helium leak testing
For optimal safety and as a more
accurate way of leak testing, Belman
offers a non-destructive helium leak
test of our products. Where a normal
leak test such as hydrostatic or soap
solution leak test offers only a limited
leak detection rate, a leak test using
helium as tracer gas, passes through
any leak due to its small atomic size.
With a mass spectrometer leak
detector, it’s possible to locate and
measure the size of leaks.
Eddy Current test
Belman offers also Eddy Current
inspections. Eddy current testing is
one of the latest non-destructive test
methods, which uses electromagnetic
induction to detect imperfections in
conductive materials. Eddy Current
test can detect very small cracks in
the surface of the material or near its
surface.
Destructive testing
In order to understand and prove
structural and material performance
under load, destructive testing can be
performed.
Belman has in-house test equipment
to carry out: burst test, cupping test
(Erichsen test), movement tests and
fatigue tests. Destructive testing is
suitable when expansion joints are
being manufactured in large quantities
or when a possible failure would have
a serious impact.
ADDED VALUES
Testing of the expansion joints are
always done according to the project
requirements and the relevant
standards. These are then recorded
in a complete manufacturing data
record book.
Our expansion joints are made of high
quality materials, from state-of-the-art
manufacturing process and qualified
and dedicated personnel.
We treat the tests and quality
procedures as an important process
which adds value to our products, but
most importantly, it delivers a guaran-
tee of quality and product confidence
for our customers.

ENGINEERING &
MANUFACTURING
State-of-the-art engineering
To meet the expectations of high
safety, engineering must be
supported by reliable and verified

VALIDATION
OF DESIGN
In certain situations, it is not immedi-
ately possible to validate the
pressurised integrity of a construction
by means of the analytical formulas
specified in the applied design
standards. For example, the geome-
trical complexity of the construction or
the need for a further optimisation of
the design could mean that the
analytical formulas cannot be applied.
In such situations, Belman can verify
the integrity of the construction by
means of complex Finite Element
Analyses. For this purpose, we use
ANSYS® and the validation is carried
out according to the terms of the
specified design standard.
The results of the analysis are often
used internally for optimisation of the
construction, but as an additional
service Belman can prepare an
evaluation report as part of the
technical documentation package.
Belman has further invested in a
market-leading analytical calculation
tool, which in addition to the stress
analysis, enables us to offer design
validation in connection with pres-
surised equipment in accordance with
the design code EN 13445.
This tool can validate flange joints,
pipe joints, spigots, supports and
lifting lugs as well as can carry out
more complex analyses, such as
Tall Tower Analysis.
The software used by Belman is
tested and validated through close
co-operation with reputable institu-
tions such as DNV-GL and TÜV who
also use this software regionally.

MATE R I A LS
Our selected material combinations
for standard expansion joints are
suitable for the majority of
applications.
The selection of the bellow material is
generally based on the following
aspects:
l Formability (Ductility)
l Weld ability
l Thermal stability
l Strength
l Corrosion resistance
l Corrosion properties such as
process media, surrounding
environment, internal cleaning
agents
l Mechanical properties: high
temperature service, cryogenic
service, operating stresses
l Manufacturing properties: forming
and cold working capabilities, cost
and material availability.
EXPANSION JOINT
MATERIALS
In particularly aggressive conditions,
special materials with high corrosion
resistance should be used. The
corrosion resistance should be at
least equal to that of the adjoining
pipe. The demand for highly flexible
expansion joints focuses on the use
of multi-ply bellows, where very
thin-walled convolutions prevent
corrosion. Whenever in doubt, it is
recommended to choose a material
with a higher corrosion resistance for
the bellows, at least for the inner ply.
In many cases, nickel-based alloys
like Inconel 600, Inconel 625, Incoloy
825 are suitable. Belman has
significant experience in working with
these materials.
The resistance tables provided in this
catalogue can be helpful in material
selection. However, the choice of a
suitable corrosion resistant material
should be based on the experience of
the user, who is most familiar with the
particular features of the system and
the operating medium.
The expansion joints in this catalogue
are supplied with documentation as
per customer request.
The following documentation can be
provided upon request:

Stainless steel
Type 300 austenitic series
1.4301 (EN 10028-7) / AISI 304
(ASTM A240 – 304)
Services a wide range of applications.
It resists organic chemicals, dyes and
a wide range of inorganic chemicals.
The alloy resists nitric and sulphuric
acids at moderate temperatures and
concentration. It is used extensively in
piping systems conveying petroleum
products, compressed air, steam, flue
gas, and liquefied gases at cryogenic
temperatures.
1.4306 / 1.4307 (EN 10028-7) / AISI
304L (ASTM A240 – 304L)
This alloy is an extra low-carbon varia-
tion of 1.4301 with a 0,03%
maximum carbon content that
eliminates chromium carbide
precipitation from the welding
process. As a result, this alloy can be
used in more severe corrosive
environments than alloy 1.4301.
It is preferred over 1.4301 for nitric
acid service.
1.4401 (EN 10028-7) / AISI 316
(ASTM A240 – 316)
This alloy has higher nickel content
than the 1.4301/304. The addition of
2-3% molybdenum gives it improved
corrosion resistance when compared
to 1.4301/304, especially in chloride
environments that tend to cause
pitting.
Typical applications are flue gas
ducts, marine service, crude oil
systems, heat exchangers and other
critical applications in the chemical
and petrochemical industries.
1.4404 (EN 10028-7) / AISI 316L
(ASTM A240 – 316L)
This alloy is an extra low-carbon
variation of 1.4401 with a 0,03%
maximum carbon. It is commonly
used for highly corrosive applications,
where intergranular corrosion is a
hazard.
1.4571 (EN 10028-7) / AISI 316Ti
(ASTM A240 – 316Ti)
With the addition/stabilising of
titanium and molybdenum, this alloy
shows very good resistance against
carbide precipitation and intergranular
corrosion.
The main advantage of 1.4571 is
that it can be held at a higher
temperature for a longer time, without
sensitising (precipitation) occurring.
Typical application areas are
chemical and petrochemical
industries, paper industry, food-
processing and heat-exchangers.
1.4541 (EN 10028-7) / AISI 321
(ASTM A240 -321)
The addition of titanium to this
stainless steel acts as a carbide
stabilising element that prevents
carbide precipitation when the
material is heated and cooled
through the temperature range
between 430°C to 900°C. The alloy
finds usage in many of the same
applications as 1.4301/304, where
the added safeguard from
intergranular corrosion is desired.
Our standard catalogue is designed
with bellows elements in this material
due to its versatility, favourable
pricing and availability.
Heat resistant steels
1.4828 (EN 10095)
High temperature steels are designed
to be used at temperatures above
550°C, in the temperature range
where creep strength are the
dimensioning factor and
high-temperature corrosion occurs.
Optimising steels for high tempera-
tures has meant that their resistance
to aqueous corrosion has been
limited. All steels are austenitic,
resulting in relatively high creep
strength values. Standardised
high-temperature steels for service at
temperatures up to 1000°C in dry air.
Utilisation in the temperature range
600-900°C can lead to
embrittlement of the material.
High alloyed steels
2.4816 (EN-10095-1) / INCONEL
600 (ASTM B168 – 600) (UNS
N06600)
This nickel-chromium alloy offers high
strength over a wide range of
temperatures together with good
resistance to a variety of corrosive
BELLOW MATERIALS
environments. It finds wide use in
steam and salt water services, where
it is virtually immune to chloride stress
corrosion.
2.4856 (EN 10088-1) / INCONEL
625 (ASTM B443 – 625) (UNS
N06625)
This alloy comes with higher
chromium content than alloy 600.
Together with the addition of 9%
molybdenum, this results in superior
mechanical strength and corrosion
resistance over a wider range of
temperatures and corrosive
environments.
It is used in many critical
applications such as heat
exchangers and FCCU (Fluid Catalytic
Cracking Unit). When exposed to
temperatures above 500°C for a
prolonged period, the alloy may
become brittle.
Similar to Inconel 625, Inconel 625
LCF, it has the same
mechanical strength and corrosion
resistance properties. But with a
slight difference in material
composition (grain size), can
enhance low-cycle fatigue properties
at elevated temperature.
1.7846 (EN 10088-1) / INCOLOY
800 (UNS N08800)
This is less expensive than the
above-mentioned nickel alloys due
to a lower content of nickel.
Good properties against oxidation,
carburisation and other high
temperature corrosions, as well as
mechanical strength at high
temperatures.
1.4958 (EN 10088-1) / INCOLOY
800H (UNS N08810)
In situations where a greater
resistance to stress rupture and creep
is required, Incoloy 800H is used
instead of Incoloy 800. Especially at
elevated temperatures higher than
816°C. Furthermore, Incoloy 800H
has a relatively good resistance to
chloride stress-corrosion cracking.
2.4858 (EN 10088-1) / INCOLOY
825 (ASTM B424-05) (UNS
N08825)
This copper-chrome nickel alloy
exhibits excellent corrosion resistance
to the most aggressive acids, in
particular against hot, concentrated
sulphuric acid and in sulphur bearing
environments. Due to its content of
nickel in conjunction with molybde-
num and chromium, the Incoloy 825
offers excellent resistance to reducing
environments, such as those
containing sulphuric and phosphoric
acids. It supports resistance to local
corrosion like crevice and pitting and
offers resistance to a variety of
oxidizing substances such as nitric
acid, nitrates and oxidizing salt. The
resistance of alloy 825 makes it the
preferred choice for various
applications such as chemical
processing, pollution control, oil and
gas recovery, acid production,
pickling operations, nuclear fuel
reprocessing and the handling of
radioactive wastes.
2.4605 (EN 100xx-1) / ALLOY 59
(ASTM B 575) (UNS N06059)
Alloy 59 is a nickel-chromium-
MATE R I A LS
molybdenum alloy with an extra low
carbon and silicon content. The alloy
has very good corrosion resistance
and high mechanical strength. It is
characterized by excellent resistance
to a range of corrosive media in
oxidizing and reducing conditions,
plus resistance to pitting and crevice
corrosion.
The alloy has outstanding resistance
to acids, like nitric, phosphoric,
sulphuric and hydrochloric acids,
including sulphuric and hydrochloric
acid mixtures.
1.4547 (EN 10028-7) / 254 SMO
(ASTM) (UNS S31254)
254 SMO is a high-alloy austenitic
stainless steel developed for use in
aggressive chloride-bearing media or
seawater applications.
The 254 SMO is recognised by a high
chromium content, but it has the
molybdenum content which gives 254
SMO excellent resistance to pitting
and crevice corrosion. The high
nitrogen content further improves
pitting resistance.
Duplex steels
Duplex
Duplex stainless steels, combine
many of the beneficial properties of
ferritic and austenitic steels. Due to
the high content of chromium and
nitrogen, and often also molybdenum,
these steels offer good resistance to
pitting and particularly stress corro-
sion Cracking. The duplex microstruc-
ture contributes to the high strength.
Duplex steels have good weldability.

The successful installation of
expansion joints in a pipe system
requires the careful consideration of
many variables.
The most important issue is to
establish the direction in which the
movements are acting and in which
way the movements should be
absorbed. Once this information is
known, the solution incorporating the
most suitable expansion joint type(s)
can be determined.
The following pages give some ideas
and suggestions for pipe system
design, and how to implement
expansion joints in the system in the
best way.
Complex pipe systems must be
subdivided into a number of less
complex sections, to ensure the
optimum movement absorption in
several directions. Each section is
usually divided by a fix point (between
each section).
Drawings
In the following pages examples of
good practice in the use of expansion
joints in different pipe systems are
illustrated. The drawings are freely
adapted from the applicable
standards and are in accordance with
the drawings available in the latest

FIX POINTS, GUIDES ETC.
Fix points and guides for
axial expansion joints
It is important that the fix point is
placed as close to the axial expansion
joint as possible. It is important to
note that only one axial expansion
joint can be installed between two fix
points. The distance between the
expansion joint and the first guide
should be a maximum of
4 x diameter. The distance between
the following guides should be
14-20 x diameter.
This is illustrated in the drawings below.
For other expansion joint types, the
position of fix points and guides are
dependent on the pipe system and
the position of the expansion joint in
the pipe system.

This illustrates the importance in the
use of the three fix points, as the use
of two or more axial expansion joints
in a piping section will create an
undetermined arrangement.

The amount of movements imposed
on each expansion joint is not
controlled, as the pipe between the
two bellows can move sideward freely
in both directions depending on the
friction of the pipe supports and the
differences in stiffness between the
bellows. It is always important to have
one axial expansion joint between two

account the full pressure thrust of the
expansion joint and, additionally, the
possible offset of the pressure thrust if
the reducer is eccentric.
Shows the application of a single
expansion joint in a pipe system
containing an offset. It should be
noted that applications of this type
are not usually recommended and will
only perform satisfactorily under
certain conditions.
As shown the pipe system is provided
with fix points at each end to absorb
the pressure, movement loading and
guide friction. Where the line contains
an offset, this load must first be
transmitted through the offset leg,
resulting in a movement on the pipe
system. Where the pipe system size is
small, the offset appreciable, or where
the pressure and movement forces
are relatively high, this configuration
may result in over-stressing, or
distortion of the pipe system and
guides. Note the proximity of the
expansion joint to a fix point and the
distance between the first guide (G1).
Further, the spacing between the first
guide and the second guide (G2) and
the spacing of guides (Gn) along the
rest of the pipe system. Guides
should be installed near both ends of
the offset leg to minimise the effects
of the bending movement on the
system.

movement of the horizontal lines is
absorbed as lateral deflection by the

sion joint. Any thermal expansion of the

The piping connected at the bottom
should be guided in such a manner

should be made in the design of the
guides to allow for both this deflection
and the reduced length of the
expansion joint in its deflected
position.
A piping configuration that permits the
use of adapted tie rods to prevent
axial movement frequently simplifies
and reduces the cost of the
installation.
Due to the tie rods, the expansion
joint is incapable of absorbing any
axial movement other than its own
thermal expansion. The thermal
expansion of the piping in the shorter
leg is, as a result, imposed as
deflection on the longer piping leg.
Where the longer piping leg is not
sufficiently flexible and where the
dimension of the shorter leg is
suitable, tie rods may be installed

no deflection is imposed on the

Hinged expansion joints can, in sets

large lateral and axial movements.
In this case, the entire deflection is
absorbed by the expansion joints and
negligible pipe bending loads will be
imposed upon the fix points.
Where the distance between the fix
point on the left and the first hinged

guide should be installed adjacent to
the expansion joint, as shown. This
pipe guide will minimise bending of

In general, there should not be more
than three angular expansion joints
installed between two fix points, of
the pipe section between expansion
joint C and the left hand fix point
which might otherwise result from the
movement required to rotate the
expansion joint. One or more
additional guides (Gn) may be used to
maintain the plane of the piping
system and relieve the hinges of
bending forces which may be created
by external loads.
Support for the piping system may be
accomplished in various ways,
utilising available supporting
structures with greatest efficiency.
It is essential that spring supports be
used to permit the free movement of
the piping between the expansion
joints.
Illustrates the use of a two-hinge
system to absorb the major thermal
expansions in a single-plane “Z”
bend. Since the pressure thrust is
absorbed by the hinges on the
expansion joints, only fix points are
required at each end of the piping
system. The thermal expansion of the
offset section containing the expan-
sion joints must be absorbed by the
bending of the piping legs perpendic-
ular to that segment, since the
expansion joints are restricted to pure
angular rotation by their hinges and
The figure illustrates the principle that
hinged expansion joint systems may
also be used in other cases where
cannot extend or compress.
The amount of bending deflection
imposed on each of the two long
piping legs may be controlled by the
effective design of guides and
supports. Where one long leg is
sufficiently flexible to absorb the full
thermal growth of the offset leg, the
other long leg may be controlled to

clearances, consideration shall be
given to the fact that the thermal
expansion of the offset piping leg
containing the expansion joints will be
partially offset by the reduction in
length resulting from the displacement
of the centre pipe system. The latter
effect may be ignored only where the
distance between hinge pins is very
large and the lateral displacement is
small.

In deploying hinged expansion joints
for the most effective use, it should be
noted that in order to function
properly the hinges do not need to be
colinear. The illustration shows a
two-hinged expansion joint system. In
this case, the expansion joints will
absorb only the differential vertical
growth between the vessel and pipe
riser. Any horizontal movement due to
piping expansion, vibration and wind
loads will be absorbed by the bending
A hinged expansion joint system may
be used effectively in applications
involving movement other than the
pure thermal growth of piping. The
figure illustrates an application
combining the thermal expansion of a
piping system with the single plane
movements of an item of connected
equipment. As long as all movements
are restricted to a single plane, the
behaviour of the expansion joint
system is quite similar to that of the
system shown in the figure. A fix point
is required at one end of the piping,

of the vertical pipe leg.
A planar guide may be installed near
the top of the vessel to protect the
hinged expansion joints from wind
loads at right angles to the plane of
the piping.
The fix point shown at the bottom of
the riser is a fix point only, since the
pressure load is absorbed by the
expansion joint hinges.
This fix point must be capable of
withstanding the forces created by
while the equipment serves as a fix
point at the opposite end. The
displacements of the equipment are
added to those of the piping to
evaluate the movements of the
expansion joints. Planar guide
clearances in the plane of the piping
must be adequate to allow for the
equipment movement as well as the
piping rotations.
The compact size and structural
rigidity are the advantages of this
expansion joint type. Through the use
of these individual units, it is
the bending of the riser. Depending
on the dimensions and weight of the
pipe system, sufficient support may
be obtained from the process vessel
and from the fix point. If additional
supports are required, spring type
supports should be used. The vertical
piping may be cold pull to reduce
bending stresses, utilising the hinges
to withstand the cold spring force.
frequently possible to compensate for
the thermal expansion of irregular and
complex piping configurations, which
might preclude the use of other types
of expansion joints. Due to the ability
of the hinge structure to transmit
loads, piping systems containing
hinged expansion joints impose
minimal forces on the fix points. Such
systems can be supported at virtually
any point, without interfering with the
free movement of the system.

This often used system absorbs
movements in any direction of the
horizontal pipes through use of the
GIMBAL
gimbals, while the hinged angular
expansion joint takes the vertical
movement resulting from the reduction
of the vertical distance between the
gimbals.
Just as hinged expansion joints offer
great advantages in single plane
applications, gimbal expansion joints
are designed to deliver similar benefits
in multi-plane systems. The gimbal
expansion joints ability to absorb
angular rotation in any plane is most
frequently achieved by utilising two
such units to absorb lateral deflection.
An application of this type is shown in
Source: Freely adapted from EN 14917/EJMA
the illustration. Since the pressure
loading is absorbed by the gimbal
structure, fix points only are provided.
Guides are provided to restrict the
movement of each piping leg. As in
the case of hinged expansion joints,
the location of pipe supports is
simplified by the load carrying ability
of the gimbal structure. Since, in a
two gimbal system, the growth of the
vertical pipe leg will be absorbed by
bending of the longer legs, spring
supports (SP) may be required on
either or both of these. Guides must
be designed to allow for the thermal
expansion of the leg containing the
expansion joints and for the
shortening of this leg due to
deflection.

In some pipe systems, the operating
conditions can be quite challenging,
resulting in special considerations for
the design of both the pipe system
and for the expansion joints. Large
movements can be absorbed in
numerous ways, and with different
expansion joint types. In many cases
installing two or more expansion joints
together at natural or contrived offsets
in the pipe system can be a good
solution to absorb large movement.
The same pipe system design can
also be used for the absorption of
angular movements, which would not
be possible in a straight pipe system.
Why U-bend/pipe loop?
The U-bend is a good solution for
absorbing larger movements. The
configuration of a pipe loop
containing 3-angular (hinged)
expansion joints can absorb, at a
minimum, three times larger move-
ments compared to a traditional pipe
loop without angular expansion joints.
The hinges on the expansion joints
contain the pressure forces from the
bellows and simultaneously ensure
that movements are controlled, which
helps to support the pipe system. The
pipe system geometry is determined
by the amount of movement to be
absorbed and the rotational capability
of the expansion joints; the higher the
movements the greater the distance
required between the centre and end
expansion joints.
The advantages of this U-pipe
system design
l Large movements are absorbed
l The stress forces on the system
fix points are much reduced
compared to those from
equivalent unrestrained expansion
joints
l Costs for fix points are reduced
l Solutions using restrained
expansion joints can prove to be
very cost effective, especially
when the pipe system is installed
at heights. The need for the
substantial fix points and guides
in the pipe system that are
routinely required with un-
restrained expansion joints,
becomes unnecessary
due to the pressure thrust force
from the bellows being contained
by the hinge structure on the
expansion joints
l As shown in the on the left,
use of expansion joints in loops
can reduce the number of loops
required from 3 to 1
Tips!
l Venting or draining may be
required if the loop is fitted
vertically
l Expansion joints should be fitted
as close to the elbows as
possible
l Guides should be close to the
outer expansion joints to direct the
pipe growth onto the bend. The
guides must allow free travel of the
pipe system and expansion joints
under all movement conditions
l The centre expansion joint in the
U-bend should absorb the rotation
equally to the rotation of the outer
expansion joints
l It is advisable to cold pull the
U-bend so that the expansion
joints work equally from their
neutral condition. This maximises
the available travel from the bend,
minimises the height of the bend
and halves the total deflection
force applied to the fix points

minimum of guiding is required,
primarily to direct the thermal

The above typifies good practice in
the use of a pressure balanced
expansion joint to absorb axial pipe
system expansion. Note that the
expansion joint is located at a change
in the direction of the piping, with the
elbow and the end of the pipe system
being secured by guides. Since the
pressure thrust is absorbed by the
expansion joint itself, and only the
forces required to deflect the expan-
sion joint are imposed on the piping,
only a minimum of guiding is required.
Directional guiding adjacent to the
expansion joint, as shown, may
suffice in most cases.
In long, small-diameter pipe systems,
additional guiding may be
necessary.

The above shows a common
application for a pressure balanced
expansion joint. Under various

the differential vertical movement is

expansion joint and the thermal
expansion from the centre line of the

PRESSURE BALANCED
Use of a pressure balanced expansion joint on a vessel
process vessel to the pipe system is
absorbed as lateral deflection. The
pipe system may then be secured by
a fix point at the bottom and furnished
with a guide adjacent to the
expansion joint.
In many cases, no external structure
is available at the upper elevation of
the process vessel and the guide
must be connected to the vessel
itself. Using this arrangement may
result in some bending load upon the
pipe system, especially where the
vessel is tall and is subject to wind
loading deflection or similar effects.
Where the guide is attached to a rigid
external structure, the expansion joint
must be designed to absorb wind
loading deflection, and other similar
loading, as lateral deflection.
connections with high forces resulting
from the pressure thrust. This is
achieved by using an additional
equalising bellow subjected to the line
pressure and interconnecting devices
between the line bellows and
equalising bellows. Each bellow
should be designed to absorb full
axial movement.
When two process vessels are to be
connected, a pressure-balanced
expansion joint will usually provide the
best solution. This solution should
include absorbing the growth of the
interconnecting pipework, accepting
movement due to any differential
growth of the vessels and catering for
the effects of any settlement. The
design of process vessels will often
prevent any significant loads from the
pipework being applied to the vessel
or nozzles. Through the utilisation of a
pressure balanced expansion joint, all
forces generated by internal pressure
In-line pressure balanced expansion joint between two process vessels
acting on the expansion joint bellows
are contained by the restraining
structure on the unit. This leaves the
spring rate forces created by the
bellows movement to be contained, in
most cases these forces are signifi-
cantly less than those of the pressure
forces and typically are easily
resolved. The alternative to using a
pressure balanced system would be
to deploy simple unrestrained
expansion joints. However, this would
require the installation of a structure
to enable fix points to be included.
This could create significant costs,
particularly when the interconnecting
pipework is at greater heights.
In some applications, a simple in-line
axial pressure balanced unit can be
used. This style of expansion joint will
accept mainly axial movement, but
can be designed to additionally
accept small lateral movements.
In more complex arrangements,
special expansion joints are required
with a twin-bellows incorporated to
accept greater lateral movements.

bellows will be subjected only to axial
movement if the tie rods are properly
designed to rotate or pivot at their

effective design, the guide can be
made directly above the turbine to

joint. In a large diameter and low
pressure application, it may be
impossible to utilise the pressure

the pressure loading or at best, the
effect may be uncertain. In such
cases, another expansion joint design

these on the turbine. The only force
imposed on the turbine is that is
required to deflect the
expansion joint laterally.
Where flow considerations permit, this
problem may be overcome by the use
of a tee as a center fitting of the
expansion joint, rather than an elbow.
In some cases, the pressure for the
balancing end of the expansion joint
has been introduced from a seperate
pressure source, but this is
considered somewhat hazardous. A
control failure or even a slow control
response might result in partial or full
pressure loading being imposed upon
the piping or equipment, thus
eliminating the initial reason for using
the pressure balanced expansion
joint.
The expansion of the turbine between
its fix point and the expansion joint is
absorbed as lateral deflection. A fix
point is used at the centre fitting of the
expansion joint. Since the expansion
joint is located close to the turbine,
guiding is not required between the
turbine and expansion joint.

Expansion joints are designed to
absorb movement according to
predetermined design data. The
calculated service life of an expansion
joint is based on the precondition that
the expansion joint will never be
subjected to mechanical or thermal
load exceeding the stated design
data. In order to achieve the maxi-
mum service life, pressure resistance
and reliability, caution should be taken
during the handling, storage and
installation of the expansion joint. The
necessary care includes adhering to
the following advice. Failure to comply

Pressure reduction factor
The factor used for reduction of

material yield strength at design
temperature [Rp], and the yield
strength at room temperature [Rpt].
Definiton: Kpa = Rp / Rpt
The reduction factor is applied to
modify the design pressure [PS] where
temperatures exceed 20°C, it com-
pensates for the decay in material
mechanical properties at elevated
temperatures. The modified pressure
must always be lower than the nominal
pressure of the standard item.
Calculation: PS / Kpa ≤ PN
Where the applied design pressure
is lower than the nominal pressure
for the standard unit an increase in
fatigue life expectancy and / or
increased movements can be
achieved.

VIBRATION ABSORBERS
Belman has developed a series of
vibration absorbers, which are
designed for versatile usage in any
system where pump vibrations occur.
The standard range is made from
multi-ply bellows with several very thin
layers of stainless steel. This delivers
maximum performance regarding:
pressure and temperature bearing
capacity, noise and vibration absorp-
tion and overall cyclic service life.
The vibration absorbers have a
standard overall length of 130 mm for
the easy replacement of any rubber
expansion joint. The range of vibration
absorbers can resolve any problems
related to mechanical vibration and
have a higher pressure and
temperature capacity than rubber
bellows. Unlike rubber expansion
joints, stainless steel bellows do not
suffer from atmospheric damage
when used in an outdoor installation.
Properties
The vibration absorbers feature
rubber bushes for the tie rods for
maximum noise and vibration
reduction. The vibration absorbers
can withstand high pressure at
elevated temperatures, with flat steel
springs holding the tie rods. The tie
rods ensure that pressure thrust forces
from the pump are not transferred to
the adjacent pipe system.
l Compensate for installation
misalignments between pipe
systems and pumps, and
thermal growth
l Eliminates pressure thrust forces
and torques on pumps and other
equipment
l Reduces vibrations, oscillations,
and noise (sound and vibration)
from pumps into pipe systems
l The multi-ply bellow ensures
maximum performance regarding
pressure, temperature and service
life
l Standard design is: 16 BarG, and
overall length of 130 mm for easy
replacement of rubber bellows
l Special designs are available to
any specification
Applications
l In pipe systems and installations
where vibrations and stresses
occur
l Pumps, compressors, engines,
burners etc.
l House installations, industrial
installations etc.
l Heating, climate, ventilation and
heat recovery installations
l Gas, water and sewage treatment
plants
Advantages
l Unlike rubber expansion joints, the
vibration absorbers are resistant
against ageing, high temperatures
and UV-radiation
l Reduction of long-term operation
and maintenance costs
l Increased reliability and
prolongation of the service life of
the pipe system and connected
equipment
l Tie rods as standard for minimum
fixation of pipe system (available
without tie rods, on request)

PRESSURE BALANCED
EXPANSION JOINTS
Pressure balanced expansion joints
are designed to absorb movements
from a pipe system. They can
accommodate axial and lateral
movements where anchoring of the
pipe system is difficult or impractical
due to structural or economic
considerations. Pressure balanced
expansion joints do not transfer the
internal pressure thrust on to the fix
points, adjacent equipment, or
structures. Fix points are usually not
required, only guides can ensure the
turning of thermal expansion into a
controlled movement.
Therefore, pressure balanced
expansion joints can offer significant
advantages, where pipe systems are
connected with turbines, pumps,
valves or other equipment, that are
unable to withstand pressure thrust
loads.
Although pressure balanced expan-
sion joints eliminate pressure thrust,
it’s important to note that the existing
load on the surrounding equipment is
the total sum of the spring rates of
both the flow bellows and balancing
bellows. The movement absorbed by
a pressure balanced expansion joint
should be understood as follows:
if the thermal movement in the
connected pipe is 20 mm, the flow
bellows of the pressure balanced unit
will contract by 20 mm and the
balancing bellows, with twice the
effective area of the flow bellows, will
expand by 20 mm.
can be designed to any specific
requirement with tie rods, with cover,
and also for the absorption of lateral
and or angular movements (universal
type).
Advantages
The advantage of a pressure
balanced expansion joint is that it
reduces the complexity and size of fix
points by eliminating the pressure
thrust, thereby delivering stability to

sion joints are available in all sizes and

the pipe system. This also reduces
the required space for structures that
carry fix points and guides.
Pipe engineers are often faced with
the challenge of limited space due to
the surrounding environment. It may
not be possible to include a number
of fix points and guides that are
normally required at high pressures.
The pressure balanced expansion
joint is the optimum solution for
additional scenarios such as a short
pipe run connecting two vessels, that
are unable to withstand the pressure
thrust loads or at heights, where
additional structures would significantly
increase costs. Pressure balanced
expansion joints are available in
various types as shown below.

PRESSURE BALANCED
EXPANSION JOINTS
COMPACT DESIGN
are expansion joints incorporating a
balancing chamber. This creates a
balancing pressure thrust, which
opposes the internal pressure thrust
force from the flow bellows.
can be the perfect solution in
situations where a fix point cannot be
installed such as a pipe system
between two vessels/equipment (e.g.
turbines, pumps etc.) or elevated pipe
systems without structural support.
In many applications, the design
parameters lead to the requirement
for a customised expansion joint type.
This can be especially challenging
when the desired expansion joint type
requires more space than the pipe
system dimensions permit. This can
sometimes be resolved by the use of
a pressure balanced expansion joint
with a compact design and a hidden
balance chamber. In many cases, this
can deliver positive economic
advantages as well as providing a
good technical solution.
can deliver significant advantages
over unrestrained expansion joints.
Especially in the cases, where the
pressure forces from the bellow
elements in the expansion joint
are high, and the provision of the
necessary guides and fix points are
difficult.
The inclusion of a hidden balance
chamber can sometimes be the most
appropriate answer when the
available space in the system is
limited, and conventional pressure
balanced units cannot be used.
All pressure balanced expansion joints
works by eliminating the force
generated by the bellows when
subjected to pressure. This force is
usually the highest force acting on the
connected equipment and pipe
system. However, additional forces
due to deflection and resulting
movements while designing pipe
system should still be considered.
Hidden balance chamber
The simple inline pressure balanced
expansion joint consists of a balance
bellow with a flow bellow positioned
at either side. The balance bellow has
an effective area exactly twice the
area of each flow bellows and
mechanical connections across the
bellows contain the pressure force.
By using an arrangement where one
flow bellow is placed inside the
balance bellow, it is often possible to

achieve a space saving of approxi-
mately one-third in comparison with
the conventional simple unit.
A further advantage of this arrange-
ment is that it usually leaves space
for longer bellows elements with
more convolutions while providing
less stiffness and minimising
deflection forces.
Pressure equalisation is achieved by
providing the medium access to the
balance chamber, which has an
effective area equal to that of the
flow bellows and using mechanical
restraints to contain the pressure
force whist allowing deflection.
Drainable solution
A commonly requested feature of
pressure balanced expansion joints
is the provision of a drain connection
for the balance chamber. This is a
simple connection with a plug,
located at the position of the lowest
point of the chamber where the
expansion joint is installed.
The drain is closed and sealed with
the plug when the unit is in service,
but can be opened to allow
drainage when the operation is
shutdown or interrupted for routine
maintenance.
APPLICATIONS
with compact design are used with
low pressure turbines, condensers
and also with pumps and other
susceptible equipments.

Elbow pressure balanced expansion
joints or corner relief expansion joints
are the types of pressure balanced
expansion joints which are used
where pressure thrust forces on
equipment or piping is unacceptable
and the direction of the pipe system
also changes. In order to understand
the primary advantage of an elbow
pressure balanced expansion joint, it’s
important to understand how an
ordinary expansion joint influences the
pipe system, in which it is installed.
When a pipe system with an ordinary
axial expansion joint installed is
pressurised, the pressure reaction
force as well as the force needed to
move the expansion joint is transmit-
ted to the pipe system. The pressure
thrust force can be considerable,
generating high demands and
stresses on the guides and fix points
used for supporting/fixing the pipe
system.
By installing a pressure balanced
expansion joint, the pressure thrust
force is balanced internally within the
expansion joint and only the spring
rate force, which is needed to move
the expansion joint is transmitted to
the pipe system.
This reduces the load acting on the
guides/fix points, which further
reduces the need for supporting
structures. This enables the use of
lighter guides that can deliver
significant savings, especially where
structural and foundation work is
impractical. This feature makes the
elbow pressure balanced expansion
joint the preferred choice for pipe
systems, where pressure thrust loads
acting on flanges and/or connected
equipment such as turbines is
avoided.
How does it work?
Elbow pressure balanced expansion
joints can be designed for absorption
of axial and lateral movement.
If only axial movement is required, the
expansion joint is designed with only
one flow bellow and one balancing
bellow after the bend.
If lateral movement occurs the unit
generally is designed with two flow

bellows, similar to a tied universal unit.
The balancing bellows are connected
to the flow bellows and pipe system
through tie rods so the balancing
bellow lengthens when the line
bellows are compressed axially and
thereby creates a constant volume.
That is why pressure balanced
expansion joints are also known as
constant volume expansion joints.
The pressure thrust force is absorbed
as a pulling force in the tie rods,
whereby the section between the tie
rods including the bend acts as a
balancing chamber. The balancing
bellows and the flow bellows have
inside the chamber exactly the same
cross-sectional area and this creates
a balance in the pressure thrust
forces. Thereby the bend/pipe system
corner is freed from any stresses.
This type of expansion joint is used
when there is a change in the
direction of the pipe system and is
considered the ideal solution on cross
over piping on turbines.

CHAMBER
EXPANSION JOINTS
The design of expansion joints for
operational plants, where the medium
has a relatively high viscosity (i.e. a
very thick medium, such as asphalt),
poses a special challenge. The flow is
more sluggish with a thick medium
due to its inner friction. This creates
the risk of the medium settling in the
convolutions of the expansion joint
and blocking the flow and the worst
case, the flow can be completely cut
off. This phenomenon is often referred
to as packing up, cooking or
caking. The fluidity of the liquid, i.e.
its ability to flow generally increases
PRODUCT RANGE
Chamber expansion joints are
customised solutions tailored for the
application. They are available in all
designs, all sizes and all materials
with higher temperatures. When
designing such solution, a chamber
expansion joint can be used to make
it possible to increase the temperature
of the media in the expansion joint
and thus improve the flow.
Usually, a chamber expansion joint is
an expansion joint with another larger
expansion joint mounted around it,
whereby a chamber is formed
between the two. The medium flows
through the inner expansion joint,
while a heating medium, e.g. oil, flows
in the chamber between the expan-
sion joints. The oil is heated and flows
through the chamber via an inlet and
an outlet respectively. On its way
through the chamber, the oil emits
heat to the inner expansion joint, thus
maintaining/increasing the tempera-
ture of the medium. This increases
the fluidity of the medium and
eliminates the risk of ”packing up”.
Is it possible to solve the
problem through insulation?
Insulation around the expansion joint
would merely postpone the problem
of flow cut-off/”packing up”. The
insulation would reduce the speed of
the heat loss. But the chamber
expansion joint supplies heat to the
medium, which is not possible
through insulation alone, as the
insulation only retains the existing
heat. This heat is not sufficient to
minimise the viscosity, nor is it
sufficient to avoid a cooling and
settling of the medium in the
convolutions of the expansion joint.
Therefore, the chamber expansion
joint is preferred over insulation for
sluggish mediums.
Chamber expansion joints
and materials
Chamber expansion joints can be
used in diverse applications and are
manufactured in all types of materials
according to the intended use.
Usually the material is determined by
the temperature as well as the type
and consistency of the medium. If the
medium is very corrosive, usually
high-alloy materials are used. The
surroundings of the expansion joint
may also influence the choice of
material. The chamber expansion
joints can be designed and manufac-
tured from all kind of materials and
also completely in stainless steel.

RECTANGULAR
EXPANSION JOINTS
In addition to our core product range
containing a wide selection of circular
expansion joints, Belman also
provides rectangular expansion joints.
Many design options
We design and manufacture rectan-
gular expansion joints with single and
multi-convolution bellows. These units
can be made with no size limitation
since they can be supplied in sections
for transport and reassembly on site.
Rectangular expansion joints can be
designed to accept a combination of
axial and lateral movement. When
significant lateral movement is to be
absorbed, a twin-bellows
arrangement is usually required.
Alternative corner arrangements can
be supplied including single and
double mitre and when necessary
with rounded corners. Frames and
bellows are available in a wide range
of materials, sizes and configurations
to suit individual customer require-
ments. These expansion joints are
invariably used as customised
solutions to expansion problems in
rectangular ducting; they are
purpose-designed and manufactured
to match the customer's unique
requirements.
Insulation of
rectangular expansion joints
To withstand conditions that have a
high internal temperature (e.g.
1000°C) and low external temperature
(e.g. 90°C), a special flow liner can be
fitted (for example made from
1.4845). The liner is made with
expansion gaps to enable it to expand
at the operating temperature without
generating unacceptable buckling at
the hot face of the liner.
As part of the installation, the void in
the flow liner is filled with an insulation
bolster comprising high-temperature
insulating materials. This reduces the
temperature across the insulation to
provide a lower “skin” temperature,
for example 90°C.
Large dimensions
If the rectangular expansion joint is
large, they can be delivered in
sections to ease transit and
installation. The unit is supplied in
PRODUCT RANGE
The rectangular expansion joints are
customised solutions and are available
in all dimensions, all sizes and all
materials.
segments of 2 or 4-sections with butt
joints in the frames on the long sides
of the unit. On installation the sections
of the bellows and flow liner are fitted
and welded into position by the
installer. The unit is fitted with
shipping bars temporarily welded to
the flange edges to protect the unit,
preventing damage during transit and
assist with its handling into the final
position at the jobsite.
Variety of materials
The bellows can be manufactured in a
variety of materials (the same as for
round expansion joints), including
austenitic stainless steels (300 series),
duplex, aluminium, titanium, and
high-nickel alloys such as Inconel,
Incoloy, Hastelloy and Monel.
Additional options
l The intermediate pipe and the
bellows can be supplied as one
single piece
l Loose flanges
l Single mitre corner (90 degree
corners) with the bellows being
welded together in the corners

369
EXTERNALLY PRESSURISED
EXPANSION JOINTS
Externally pressurised expansion
joints are the perfect solutions when
the expansion joints must absorb very
large axial movements under high
pressure. In principle, there are no
limits to the size of axial movement
that can be absorbed by this type of
expansion joint.
In externally pressurised expansion
joints, the bellows element(s) is
arranged so that the media flow is on
the external side of the bellows, while
the inside part of the bellows is only
subjected to atmospheric pressure
with this side being in direct connec-
tion with the atmosphere. External
pressurising of the bellows eliminates
pressure instability as a design
limitation and permits the absorption
of large axial compression. Where an
internally pressurised bellows will
become unstable and buckle due to
internal pressure, the pressure around
an externally pressurised bellows will
have a stabilising effect on the
bellows. This makes it possible to
achieve a construction with great
flexibility for large axial compensation.
With only the outside of the bellows
subjected to pressure and the
convolutions packed under a cover,
the perfect conditions for external
insulation or underground installation
can be achieved.
As the convolutions are well protected
under a cover, transport damage to
the convolutions is unlikely to occur
but most importantly, the cover offers
maximum protection against leaking
bellows or bellows failure.
The main advantages of an externally
pressurised expansion joint are:
l Compensation for large axial
movement with relatively low
spring rate
l Through the inner sleeve, a
smooth flow over the expansion
joint is achieved and thus pressure
loss is minimised
PRODUCT RANGE
The externally pressurised expansion
joints are customised solutions and
are available in all dimensions, all sizes
and all materials.
l Maximum outside protection for
any person, close to the unit in
case of a leakage
l The outside cover protects the
bellows during transport and
installation, thus increasing safety
l Drain spigots in the cover make it
possible to drain the pipe system
following pressure testing
Cover
The cover is often subject to relatively
high stresses through the combina-
tion of diameter and pressure with the
choice of material for the cover being
based on the operating conditions.
In some cases, high strength steel
can minimise the total weight of the
unit compared to regular steel types.
Drain
In order to avoid corrosion, it may be
desirable to have the capability to
drain the medium surrounding the
expansion joint. This is possible with
this expansion joint design.

371
FCCU
EXPANSION JOINTS
FCCU is one of the most important
units in the oil refinery as it converts
heavy distillates into lighter ones
(gasoline and diesel), which increases
the yield and efficiency of the refining
process. The feedstock is mainly
vacuum gas oil mixed with refinery
residues heated to extremely high
temperatures (around +700°C to
800°C), making this application very
critical. Consequently, the expansion
joints utilised in this application are
the most technically advanced among
all the existing types. The design and
manufacturing of which requires great
expertise and capability. There are
only a handful of manufacturers on
a worldwide scale having the
expertise to produce these units, and
Belman has now joined this exclusive
group.
FCCU types
l Cold wall expansion joints
l Hot wall expansion joints
Experience
We design and manufacture FCCU
expansion joints according to
customer specifications. We are able
to design and manufacture according
to various standards specified by
globally active companies engaged in
the refining industry, such as UOP,
Shell, ExxonMobil and more. We are
familiar with various specifications and
with project and/or customer
requirements like clamshell options in
the design phase. We are also
accustomed to consulting clients
concerning design enhancements to
improve and streamline the original
specified solution.
PRODUCT RANGE
FCCU units designed and manufac-
tured by Belman are typically supplied
up to DN 1800, up to 27 metric tons
in weight and up to 13,5 meters in
length. FCCU units are customised
solutions for the client and the
application.

373
CROSSOVER BELLOWS
Crossover bellows are another
example of the specialised expansion
joints. These are installed at steam
turbines where high-pressure/high-
temperature steam is transferred to
one or more low pressure turbines.
This system increases efficiency by
taking the remaining energy in the
steam and pass it through the
high-pressure part of the system, thus
using it to drive the machines at the
low pressure section.
The special expansion joints are
installed in the pipe system connecting
the turbines where they absorb the
thermal growth of the pipe system
together with any movement of the
turbine nozzles occurring under load
conditions.
The advantage of
crossover bellows
The introduction of crossover bellows
enables the thermal and mechanical
movements to take place without
imposing unacceptable loads on the
turbine casing.
A pressure-balanced arrangement is
invariably used to eliminate any
pressure forces from the bellows in
the expansion joint, and it would be
impractical to provide separate fix
points on the pipe system to contain
these loads. Good expansion joint
design results in minimal loadings to
the turbine casings as to improve the
efficiency and reliability of the turbines
that are one of the most critical parts
of a power plant.
Types
Crossover bellows are available in all
types to suit the turbine and are
typically bespoke items.
The types can be:
l Pressure balanced
l A hooded design
l Tied unit (gimbals, hinged or tie
rods)
PRODUCT RANGE
Bellow types
Crossover bellows are available in
several bellow types and in both
single-ply and multi-ply.
All sizes
Crossover bellows are available in all
sizes, all materials and all types.
l Combination of angular and lateral
expansion joints
Crossover bellows are invariably
custom-designed to suit the arrange-
ment of the turbines and intercon-
necting pipe system. Depending on
the pipe arrangement, the expansion
joint type may be an articulated
design, corner relief design, hooded
design or a combination of angular
and lateral expansion joints. A very
important part of the design process
is that the expansion joint designer
ensures that the forces and move-
ments resulting from thermal and
mechanical movement are within the
acceptable limits speciﬁed by the
turbine manufacturer. The turbine
exhaust nozzles are normally the
most sensitive to mechanical loads.
Application
Crossover bellows are mainly used on
steam turbines (exhaust, condensers
and crossover piping).

375
EXPANSION JOINTS FOR
LPG-/LNG CARRIERS
LPG-/LNG carriers are vessels
designed especially for the transpor-
tation of Liquefied Petroleum Gas and
Liquefied Natural Gas.
There are primarily three different
ways of transporting these liquefied
gases. They are categorised as
follows:
l Fully pressurised
l Fully refrigerated
l Semi-pressurised and Semi-refri-
gerated
All of these methods for transporting
the gas set various demanding
requirements for the tanks and the
tank system design. Normally the gas
on board the carriers is stored in
cylindrical or spherical steel tanks.
The vessels usually are designed with
4-6 tanks along the centreline of the
vessel. A combination of ballast
tanks, cofferdams and voids are
surrounding the tanks. Pumps are
installed inside the tanks. All the cargo
pumps are discharged into a
common pipe, which runs along the
deck of the vessel. It branches off to
either side of the vessel to the cargo
manifolds used for loading or
discharging. On the carrier, each gas
tank is mounted on an anchoring,
which allows the gas tank to move.
In order to absorb these movements,
an expansion joint is installed at each
anchoring. The tank is supported
around its circumference by the
equatorial ring, which is supported by
a large circular skirt that takes the
weight of the tank down to the hull
structure. This skirt allows the tank to
expand and contract during cool
down and warm-up operations.
During cool down or warm-up, the
tank is able to elongate or compress
(expand or contract) by 2 feet.
Because of this expansion and
contraction, all piping enters into the
tank via the top and is connected to
the ships’ lines via flexible bellows
that will result in movements in the
tank settlements.
PRODUCT RANGE
Expansion joints for LNG-/LPG carri-
ers are customised solutions designed
to fit the application. They are
available in all designs, all sizes and all
materials.
TYPE APPROVALS
Belman holds type approvals for IGC
cargo and process piping from among
others: BV, LR, DNV-GL, ABS and
KRS.
Demanding requirements
Due to the demanding design
parameters and the severe conse-
quences following a possible failure,
the expansion joints used for such
applications must also meet very high
criteria:
l The design phase is rather
complex as the design must meet
both requirements in the
classification Society Rules (e.g.
Bureau Veritas) and the Interna-
tional Rules for Gas Carriers (IGC
Code)
l Every design has to pass a burst
test of 5 times the design pressure
and the fatigue life of the
expansion joint must be verified
l The mechanical properties of the
materials used for the expansion
joint must be verified through
comprehensive testing,
especially the strength and
ductility of the materials
l Every expansion joint has to pass
a pressure test of 2 times the
design pressure
l Special requirements regarding
welding procedures and welding
consumables are also applicable
All of these tests/documents must
be witnessed and approved by a third
party surveyor.

377
PANTOGRAPHIC
LINKAGE
Expansion joints can incorporate
multiple numbers of bellows in one
unit, depending on the movement
that they should compensate and the
installation environment.
Several bellows in a sequence allow
the absorption of very large
movements, but in order to ensure a
uniform movement of each bellow, a
pantographic linkage is needed.
Pantographic linkages are devices
that distribute the total amount of
axial movement and divide it equally
to each bellow within the unit, in order
to avoid the premature wearing out of
some bellows.
Pantographic linkages can be
designed to absorb not only axial
movement, but also single and
multi-plane lateral movements.
Gimbal pantographs
Expansion joints that need to absorb
lateral movements in two different
planes would require the pantographic
linkage to be connected with a gimbal
ring on the centre of the unit.
PRODUCT RANGE
Expansion joints with pantographic
linkage are customised solutions
designed to ﬁt the application. They
are available in all designs, all sizes
and all materials.

379
EQUALISING RING REINFORCED
EXPANSION JOINTS
Belman designs, manufactures and
delivers high pressure expansion
joints with ring reinforcement. We
have successfully manufactured
expansion joints with different
dimensions and for different applica-
tions, designed for a working
pressure of more than 185 bar.
Why ring reinforcement?
By supporting a multi-layered
expansion joint bellows with ring
reinforcement, an optimum combina-
tion of both pressure integrity and
service life is achieved. A 100%
pressure test is always performed to
prove the ring’s pressurised integrity.
Belman can deliver expansion joints
with ring reinforcement in accordance
to EN 13445, EN 14917 or EJMA.
The rings are usually fabricated from
stainless steel or other suitable alloy
steels, from round bar or flat steel
products, which are then precisely
machined to suit the convolutions
profile. In order to ensure the
dimensional integrity with each
convolution, the rings are always
subjected to a full visual check.
Equalising rings and reinforcing ring
bellows are usually chosen for
high-pressure installations. Equalising
rings are solid stainless steel rings
fitted externally on the bellows.
PRODUCT RANGE
Ring reinforced expansion joints are
customised solutions designed to fit
the application. They are available in
all designs, all sizes and all materials.
The rings are precisely machined so
they fit into the root between each of
the bellows convolutions. The
purpose of the rings is to reinforce the
bellows against internal pressure. By
adding moment of inertia to the
bellows cross section, this
counteracts the bellows ability to blow
out or buckle (also called squirm) and
enhances its stability and pressure
integrity. Bellows with reinforcing rings
can be made for any type of
expansion joint (axial, lateral or
angular etc.)
The disadvantage of the ring
reinforced bellows solution is the
significantly increased stiffness of the
bellows and their limited movement
properties.
Special ring reinforced solutions
For expansion joints with demanding
operating conditions (like in the photo
on the left page), the ring reinforce-
ment is designed with bellows of
thicker plies, of duplex stainless steel
for additional strength. The reinforce-
ment rings are supported by tie rods,
which are connected to lugs. The
improved flexibility of the expansion
joints is further enhanced by an extra
balancing bellow, which in combina-
tion with the pressure balanced
design help to bring the reaction
forces towards an acceptable level.

381
CLAMSHELL
BELLOWS
Clamshell bellows provide a very
effective solution when a quick and
unplanned replacement of the bellows
is needed. Clamshell bellows are
two-pieces expansion joints that are
welded together on-site. They can be
introduced retrospectively when the
existing bellows lose their ability to
contain pressure. The purpose of
clamshell bellows is to provide a very
quick remedial solution with the least
disruption to the operation of the pipe
system. The use of clamshell bellows
invariably yields huge cost savings
when compared against the cost of
the manufacture and fitting of a
completely new expansion joint. They
can be designed as either temporary
or permanent solution and as an
over-sized or same-sized clamshell
bellows.
Over-size-clamshell bellows
These are mounted on packing rings
and welded to the outer surface of
the pipe or pressure vessel on either
side of the existing bellows. These
rings are sized so that the bellow in
the clamshell bellow is installed over
the original bellow. The clamshell
bellow is welded to the packing rings
and the pressure is finally sealed by a
longitudinal butt-weld joining the
bellow convolutions. Providing that,
the system temperature or any
leakage from the original bellows
does not constitute a safety hazard.
The clamshell bellow can be fitted
while the system is still fully
operational, meaning no system
downtime is required. The original
bellows together with any inner
sleeves or insulating materials are left
in place and are not directly
affected by the installation of the
clamshell bellow. Fitting an oversize
clamshell bellow will inevitably
result in an increase in the bellows
deflection forces with a small increase
in the effective area. This aspect has
to be evaluated by the system
designer as part of the change-ma
nagement process and our project
engineers will be pleased to
provide information in respect to this
point.
PRODUCT RANGE
Dimensions
DN 400 to DN 6000 supplied in two
pieces and DN 6000 and up to
DN 12000 supplied in three or more
segments.
ANIMATION
Visit the Belman Group channel on
www.youtube.com to see how the
clamshell bellows are installed.
Same-size-clamshell bellows
Installation of same-size clamshell
bellows requires a shutdown of the
pipe system. The existing bellows are
stripped from the pipe system or
pressure vessel and replaced by new
bellows sized to match and mounted
directly onto the original pipe system.
The tangents on the bellows are
welded to the outer surface of the
pipe system, as with an over-sized
clamshell and the convolution halves
are connected using a longitudinal
butt-weld at each joint. Same-size
clamshells can usually be designed
so that the stiffness and effective
area exactly or very closely,
match the original bellows.
It results in zero or negligible changes
to the performance characteristics.
On-site installation
Installation of metallic expansion
joints and in particular clamshell
bellows requires skilled and
experienced installation
professionals. In many instances
customers prefer the manufacturer to
perform such installation work to
minimise the risks from an incorrect
installation.
In these cases, our on-site service
team of skilled and certified welders
expertly assists our customers.
Types
Round and rectangular bellows for
any application.
Materials design
A wide range of materials and
configurations is available to suit the
materials of the pipe system and
original expansion joint.

EXPANSION JOINTS
SUPPLIED IN SEGMENTS
The increasing demand for higher
volume and efficiency has led to the
growth in the scale of production
plants. Belman meets this shift in
demand by manufacturing very large
expansion joints in sizes where the
transportation of the intact unit is
challenging.
Belman has manufactured
expansion joints up to DN 12000 in
size. With the delivery being made in
segments, the logistics is the only
limitation.
If expansion joints have a large
dimension and the installation
space is extremely limited and maybe
even complex (e.g. the expansion
joint is going through levels), a smart
delivery solution is needed.
In such situations Belman
recommends the expansion joints
supplied in segments for the later
assembly on-site.
Belman can supply bellows in
segments, which can be ﬁtted and
welded together at the place of
installation through our highly skilled
on-site service team.
PRODUCT RANGE
Expansion joints supplied in segments
are customised solutions designed to
ﬁt the application. They are available
in all designs, all sizes and
all materials.

LENS EXPANSION JOINTS
Lens expansion joints are the custom
requirements in cases where the
application requires a single layer
bellow. If the material thickness of the
single layer bellow is more than
4 mm, the supply of a normally
manufactured bellow is no longer
possible. In this case, a lens expan-
sion joint is the optimum solution.
Normally issues concerning material
thickness are solved by the supply of
a multilayer bellow but in some
cases, this is not accepted by the
customer and/or the application.
Construction
Lens expansion joints are
constructed as illustrated on the
drawings below.
As it is shown, lens expansion joints
are supplied either as a half
convolution, a complete convolution
or as a bellow. According to the
customer's requirements, these are
either delivered already welded
together or they can be welded
together on-site.
Lens expansion joints can be
constructed in all types of stainless
steel and in material thickness
1,5-8 mm. Other dimensions and
materials can be discussed upon
request.
The construction parameters are as
follows:
l Radius (R): 15, 20, 30, 50, 60
and 80 mm
1,5 mm: Max. R =15
2+3 mm: Max. R =30
4+5 mm: Max. R =60
6+8 mm: Max. R = 80
l Diameter: up to DN 2500
Larger dimensions can be
discussed on request
l Design according to: EJMA,
EN 14917, ASME or AD2000
Advantages
Lens expansion joints are preferred in
all industries that uses pressurised
equipment and heat exchangers and
where the higher pressure and higher
temperature require greater material
thickness.

ON-SITE SERVICES
It is crucial that the pipe system runs
smoothly without the risk of unexpec-
ted, problematic and costly shut-
downs. To achieve a trouble free and
reliable operation, all of the compo-
nents of the system must be well
managed including the expansion
joints. To obtain the maximum beneﬁt
from an expansion joint, it is not only
important to consider its design and
construction features, but also its
function as part of the overall pipe
system design. Further, key issues
which critically affect performance are
the location of the expansion joints in
the system, its correct installation and
planned inspections during its service
life. Having carefully considered these
factors, we have extended our core
competences from the design and
manufacture of expansion joints to
services such as:
l Installation
l Repair/refurbishment
l Clamshell bellows
l Inspection
l Engineering service
These services are performed by our
engineering and worldwide on-site
service team. The team is experi-
enced in all industries and available to
respond to urgent requests. We also
service expansion joints that were not
of our original manufacture.
Ensuring savings
and effective solutions
Repair of the existing expansion
joint/-s is often more effective than
buying a completely new unit.
Replacement of wearing parts such
as the bellows in an expansion joint
can be the most efficient solution that
ensures both cost savings and an
extended service life. For example,
repairs to the bellows of an existing
unit can deliver almost the same
service life as a completely new
expansion joint.
Belman undertakes repair and
refurbishment work both on-site and
in our workshop. Our engineers are
always ready to advise on the most
efficient solution.

TE CHNI CA L I NFOR MATI ON
The bellows are the main component
of an expansion joint, and it allows
flexibility in axial, lateral and angular
directions. Expansion joints usually
consist of one or more bellows which
gives it its flexibility. Depending on the
scale of the movements, the bellow
can have a single convolution, or a
series of convolutions. Metallic
U-shaped bellows in particular offer
great flexibility and the shape of the
convolutions provide adequate
strength for good pressure resistance.
Bellows design
Depending on the application,
Belman bellows can be manufactured
as a single-ply or multi-ply
construction. Belman can advise
which type of construction is suitable.
The single-ply bellows are made of a
single-ply metal cylinder that is
formed into u-shaped convolutions
perpendicular to the cylinder centre
line.
Single-ply bellows
Single-ply is recommended for certain
applications, due to following
reasons:
l Applications with aggressive
corrosion (corrosion problems)
l For clamshell bellows: e.g.
change of a leaking bellow, or
repair of existing bellows with the
pipe system in service
l If large convolution heights are
needed (for extremely flexible
bellows like lens expansion joints)
l Applications with abrasive media
(in such situations, single layer
bellows can have an advance)
l Lens expansion joints
l Thick-wall type of expansion joints
l Special styles of membranes (for
instance S-shaped style, and
bellows for butt-welding to existing
pipes)
Multi-ply bellows
Belman multi-ply bellows are the best
technical solutions with regards to
flexibility, safety and overall perfor-
mance. Belman multi-ply bellows
always consist of multiple, pres-
sure-tight longitudinally welded tubes
made of austenitic stainless steel or
another high-alloyed material. Each
tube forms a pressure tight and closed
layer. The tube is precisely cut, so that
they fit closely over each other and
can be telescoped together to form
the total bellows wall thickness
needed for the specified pressure
range. After assembly of the
multi-layered cylindrical pack, the
u-shaped convolution is formed.
Multi-ply bellows provide the required
wall thickness by the provision of
many plies of thin layers and as result
of which, they have the strength to
withstand high pressures and
temperatures, but with the material
stress and flexibility as each
sub-divided ply.
Generally, multi-ply bellows are more
compact than the single-ply bellows.
This results in a shorter overall length;
required built-in space and the
reduced bending stress considerably
increases the flexibility and decreases
spring rates.
The advantages of multi-ply bellows
are:
l Resistance to very high pressure
l High flexibility
l Short construction overall length
l Low displacement forces/spring
rates
l Large movement absorption
l Small convolution height
l Vibration absorption
l Optimal burst resistance,
and high safety
l Optional early leak indication,
through leak monitoring
l Economical use of high alloy
materials like Inconel, Incoloy,
titanium, Hastelloy and Tantal
l Excellent solid-borne sound
absorber
Spring rates
A bellow can be compared to a steel
spring with the spring rate being an
expression of the force required to
move the bellows through a specified
movement. Multi-ply bellows have a
considerably lower spring rate
compared to single-ply, as sub-
dividing the pressure-bearing wall into
thinner layers of steel reduces the
bending stresses equal to the
numbers of plies. The positive result
of very flexible multi-ply bellows and
low spring rates is that less force acts
on the fix points and equipments
adjacent to the expansion bellows,
which is an important cost saving
factor.
Cost savings of multi-ply
expansion joints
In situations where the expansion
joints are exposed to aggressive
media and could lead to problems of
corrosion, a very economical solution
is the manufacture of only the inner
ply (plies) in corrosion resistant
material whereas the external layers
produced in a less expensive ordinary
stainless steel. This is due to the fact
that corrosion resistant material is
very expensive. When using this cost
effective option, the weld ability of the
different plies of materials together
into one should be ensured, or
alternatively the use of loose flanges
should be considered as an alterna-
tive option.
Leak monitoring
In any installation and application,
downtime can be very expensive.
To prevent possible downtime and to
ensure predictability, Belman multi-ply
bellows can be monitored permanent-
ly for leaks with an advanced two-ply
testable system. Two-ply testable
bellows should not be compared with
standard multi-ply designs, as each of
the two layers is designed for the full
line pressure, temperature and cycles.
If one ply fails, the second ply will take
its place until a scheduled outage can
be made or when replacement/repair
can be executed.
Belman two-ply testable bellows play
a valuable role in lines with a critical
medium such as toxic, flammable,
explosive or other critical media. To
prevent the escape of the medium
following the bellows failure, it is
necessary to monitor the integrity of
the bellow's inner or outer ply.
Essentially there are two types of
two-ply testable bellows: Passive and
Active.
Passive
Passive two-ply testable bellows
monitor the pressure between the
bellows plies. If the inner ply is
breached, the line pressure will build
up between the two plies, and
pressure can be read on a pressure
gauge or monitor. Passive two-ply
testable bellows can only monitor an
inner ply breach.
Active
Active two-ply testable bellows require
a vacuum between the plies, depen-
ding on the pressure reading on the
gauge, an inner- or outer ply failure
can be detected. If the inner ply is
breached, the vacuum between the
plies will be lost and the incident is
detected as an increase to the line
pressure on the measuring monitor.
If the outer ply is breached the vacuum
will be lost, and thereby it can be
determined whether the inner or outer
ply has failed.
Vibration
Standard expansion joints are mainly
designed for compensation of static
movements like thermal expansion.
The advantage of multi-ply bellows
with its structure of several thin plies
also allows compensation of dynamic
vibrations from rotating machinery,
when the vibrations are defined in
terms of frequency and amplitude.
Due to the compact layer structure
and the friction effect of the plies
sliding on each other, Belman
multi-ply bellows have a positive
damping effect of the energy
consumption from vibrations.
An additional benefit from multi-ply
bellows is their excellent isolation
against solid borne sound.

Bellow geometry
Expansion bellows must be designed
in accordance with two contradictory
demands. First, the strength and
rigidity should be in accordance with
the specified design pressure and
temperature. Secondly, it must deliver
the required flexibility to compensate
for the movements given.
The specified design pressure should
be calculated as accurately as
possible. An overstated design
pressure would require a greater
bellow material thickness, in order to
generate the strength for the
pressure. However, thicker bellow
material results in an adverse effect
on the bellow fatigue life and spring
rates.
The opposing demands of pressure
stability and flexibility can best be
resolved through the geometry of the
convolutions. Toroidal shaped
(Omega shaped) convolutions are
highly pressure resistant but less
flexible for larger movements.
The U-shaped convolutions are the
best form for pressure reliability and
flexibility.
It is possible to enhance the
characteristic of a bellow to a very
specific requirement by changing its
geometry. Particularly multi-ply
bellows can, to a greater or lesser
extent, be designed to handle specific
requirements.
It is possible to increase the quantity
of layers for higher pressure while the
movement flexibility is retained.
Therefore multi-ply bellows are
considered as the best technical
solution.
The bellow capacity is mainly
determined by the following variable
parameters:
l Pipe diameter (D)
l Bellows ply thickness (t)
l Convolutions pitch (q)
l Convolution height (w)
l Convolutions radius (r)
l Number of plies (n)
l Bellows reinforcement
l Bellows material
l Bellows heat treatment
Each of the above parameters are
used in a complex set of equations by
the specified design code (EN 14917,
EN 13445, EN 13480, AD 2000,
ASME B31.1, ASME B31.3,
ASME VIII Div.1, EJMA) that
evaluates: pressure related stress,
stress of movement deflection, creep
stress due to temperature, instability,
spring rates and fatigue cyclic life.
Design parameters effect
on bellow performance
The variable parameters and their
influence on combined stresses
imposed by movements, pressure
and temperature is best described by
the below figures.
Cyclic fatigue life of bellow
The expected cyclic lifetime of a
bellow or expansion joint assembly is
an overall value, which express the
bellow performance. The cyclic life is
defined as a total number of move-
ment cycles that can be expected
from the bellow.
The cyclic life is determined by
various parameters such as pressure,
temperature and the bellow geometry.
Any change in these factors will result
in a change in the cyclic lifetime of the
bellow/expansion joint. If the bellow is
to be designed for a certain expected
number of cycles, then Belman must
be made aware of this at the design
stage. Normally expansion joints are
designed for an expectancy of 1000
cycles.

Punch forming
Punch forming or expansion forming
is done on an expanding mandrel.
The cylinder is positioned over an
expanding mandrel, which punches
each individual convolution by
drawing material from the top and
bottom of the cylinder.
As the top and bottom of the cylinder
is supported by the machine, any
thinning of the material is eliminated.
After the punch process, the corru-
gated cylinder is rolled in a series of
bronze wheels in order to optimise the
uniformity of each convolution.
Rolled forming
Rolled forming is a mechanical
forming method, which is mainly used
for bellows with either very large or
very small diameters. The cylinder is
positioned in a machine where a shaft
with wheels inside and outside the
cylinder forms the convolutions while
the cylinder is rotating over the shaft.
During the forming process the wheels
on each shaft are constantly
repositioned. The bellows cylinder is
longitudinal shortened while each
individual convolution is made in the
forming operation.
The forming method is ideal for large
size bellows as there is no limit to the
cylinder size. The bellows machine can
even be delivered to the site, removing
the problem of the transportation of
oversized bellows.
Hydraulic forming
With hydraulic forming, the cylinder is
placed in a hydraulic bellows machine
and perfectly sealed by two end plates.
The outside of the cylinder is clamped
with dies equal to the required number
of bellows convolutions. Each die
internally has the same geometry as
one convolution. The bellow is formed
by pumping liquid under high pressure
into the cylinder and the cylinder slowly
expands into each die. All the convolu-
tions are formed simultaneously
without overstretching of the material.
This gives a quick and economic way
to form bellows, which is particularly
beneficial on larger production
quantities.
Elastomer forming
The cylinder is placed over a mandrel,
with a compressible rubber ball,
hydraulic force compresses then the
rubber ball, which expands inside the
cylinder. The cylinder expands then
externally into an external die with and
internal u-shape. After one convolution
has been expanded out by the rubber
ball, the rubber compression is
released again, the cylinder shifts its
position and the process is repeated
until the required number of
convolutions is made.
With this process, it is possible to form
cylinder diameters as small as DN15,
where the cylindrical diameters are
limited by mandrel and die sizes.
The difference
Some rolled convolution styles have a
slightly reduced inner bore, which can
be a disadvantage in systems with
high flow volume or flow velocity.
As this can result in a higher back
pressure on smaller diameter bellows
sizes while it has minimal impact on
larger size bellows. The majority of our
bellows have a strait internal bore,
which has a low impact on internal
flow and offers more options regarding
different inner sleeves and connections.
Flanges and welding ends are mounted
equally on both convolution styles.
The bellow element is the most
crucial part of an expansion joint as it
allows movement flexibility while
containing the pressure and media.
Belman manufactures bellows in
uncompromising quality. The manu-
facturing process is performed by
highly skilled and qualified personal in
accordance with internationally
recognised quality standards.
The manufacturing starts with a
single-ply or multi-ply metallic
cylinder. The cylinder(s) is primarily
made from stainless steel sheets in
various thicknesses from 0.2 – 6.0
mm, but can be made from any
quality material.
Multi-ply bellows are several metallic
cylinders made from sheets, which
are precisely cut and rolled into tubes.
Each tube is then welded to a closed
cylinder and each cylinder is
telescoped together, to form one multi
walled cylinder. The finished cylinder
goes then through a unique forming
process depending on the
convolutions geometry.
Belman produces bellows using
state-of-the-art technology, using the
following different forming methods:
l Punch forming (expansion)
l Rolled forming
l Hydraulic forming
l Elastomer forming (rubber
expansion)
All Belman forming machines are
CNC controlled (Computerised
Numerical Control), which ensures
totally uniformity. Each method has
specific advantages or disadvantages
in different situations.

STRESSES
IN THE BELLOWS
The system pressure and deflection
create the major stresses on the
bellows. The ability of the bellows
membrane to withstand pressure is
measured by hoop stress, which is
the normal stress acting
The tangent (collar) stress and
circumferential convolution stress must
not exceed the maximum allowable
stress, which is set by applicable
standard or the customer´s
specification.
The bellows ability to withstand
pressure is also limited by meridional
pressure stresses, which run
longitudinal to the bellows center line.
More specifically, those stresses are
located in the bellows side wall and
produce the tendency for the bellows
convolutions to become less U-shaped
and more spherical.
The bellows meridional membrane
stresses due to pressure are designa-
ted as σ(m,m) and σ(m,b), or S3 and S4
in the EN and EJMA calculations:
circumferentially due to pressure
difference inside and outside of the
bellows. The circumferential stress
includes the bellows tangent and
collar as well as convolutions. This
stress must be held in accordance
with a specified stress level norm.
The Standards of EN 14917 and the
Expansion Joint Manufacturers
Association, Inc. (EJMA) define the
bellows tangent membrane stress
due to pressure as σѳ,t or S1:
The convolution circumferential
membrane stress due to pressure is
designated as σѳE or S2 in the EN and
EJMA calculations:
Bellows tangent circumferential stress due to pressure (S1)
Collar circumferential membrane stress due to pressure (S1´)
Bellows hoop stress circumferential membrane stress due to
pressure (S2)

Bellows deflections are continuously
repeated a number of times. For this
reason, Belman expansion joints are
designed as standard to handle a
minimum of 1000 lifetime cycles with
one deflection being expressed as
one cycle.
Within the movement range of an
expansion joint, cyclic life can be
increased by reducing the actual
movements, or movements may be
increased by reducing the expected
cyclic lifetime; it simply depends on
the actual situation.
Expansion joints are usually designed
to absorb deflections, which are
generated by the changes in
temperature that occur each time a
system is started and stopped. By
relating the number of cycles to the
numbers of start-up and shutdowns
of the system over a period of time, it
is possible to predict when the
bellows will be worn out or meet
fatigue failure. Having this knowledge
gives the ability to order replacements
in time for the next coming outage.
Movements and cyclic life
When predicting the lifetime of an
expansion joint, it is very important to
ensure that the expansion joint
manufacture has the correct
specification for the lifetime cycle and
movement characteristics.
If required, an expansion joint can be
designed for a range of movements
and as the overall lifetime is related to
the magnitude of movements. It is
important to consider all possible
deflections in the system which
include:
l Installation misalignment
Which is normally a one time
occurrence and can be avoided by
a correctly aligned pipe system.
l Settlement
Foundation or ground settlements
are normally considered as
one single movement, but this
depends on the actual situation.
l Start-up and shutdown
A given number of cycles which
can be predicted by the
temperature deflections from cold
to maximum operational tempera-
ture due to the start-up and
shutdown of the system.
l Operational movements
Movements that are generated by
temperature changes during
operation, for example, an engine
lying idle and then running at full
speed, is characterised by
movements with a low amplitude,
and a high frequency/number of
cycles.
SERVICE
LIFETIME
l Exceptions
Movements that happen in
exceptional circumstances such
as earthquakes, water hammer
effect and other emergency
situations. Normally these
happen as only a few cycles
but with large movements.
l Vibrations
In the event of vibrations occur
in the system, Belman must have
information about both the
amplitude and the frequency.
If the vibrations within the system
are close to the natural frequecies
of the bellows, there is a risk of
resonance failure of the bellows.
Vibrations are usually of a low
amplitude, but with a very high
number of cycles that can
induce an early fatigue failure.
Accumulated fatigue
Belman must have all relevant
information, because a pipe system is
known to have multiple movement
characteristics as explained earlier.
The accumulated fatigue lifetime is
determined by Miner’s rule of linear
accumulation.
Belman can predict when a bellow is
ready to be replaced hence ensure
the highest quality of our
products.
For bellows which are not annealed
after forming, meridional membrane
and bending stresses due to pressure
are allowed to exceed the initial material
yield strength by a large margin
because it is cold formed. In cases of
bellows which are annealed after
forming, the stresses must be limited
because the bellows side wall material
are no longer cold-formed. It is
common practice not to anneal bellows
after forming so as to benefit from the
added performance that is imparted to
a bellows through the cold forming
process. The other meridional stresses
that are evaluated in EN and EJMA are
the bellows meridional membrane and
bending stress due to displacement of
convolution designated as σ(m,m)
(equivalent displacement) and σ(m,b)
(equivalent displacement) or S5 and S6:
Bellows meridional membrane stress due to deflection (S5)
Bellows meridional bending stress due to deflection (S6)

CONNECTION ENDS
Welding ends
Expansion joints with welding ends
are those which are welded into the
pipe system. Depending on the
diameter of the welding ends, they
are made from welded pipe, seamless
pipe or from rolled sheet metal. If the
pipe system requires, it is possible to
design an expansion joint with a
welding end in one end and a flange
in the other end. Welding ends are a
simple, cost effective and easy to
implement solution. Installation of an
expansion joint with welding ends into
a pipe system requires welding and
inspection on-site with an experi-
enced installer.
It is considered more complex to
replace expansion joints with welding
ends than those of expansion joints
with flanges.
Welded flanges
Welded flanges are welded onto the
expansion joint. Expansion joints with
welded flanges are suitable for
applications with high pressure, but
generally need a sealing gasket in
order to make a perfectly tight
connection.
Welded flanges are a more expensive
solution than welding ends. On
expansion joints with welded flanges,
the flange holes will be inline, which is
important to notice when reordering
or installing an expansion joint. If the
flanges in the pipe system are not
inline, it can be wise to order
expansion joints with loose flanges.
Expansion joints with welded flanges
can be quick to install and are easy to
replace.
Loose flanges
Loose flanges are also known as
swivel flanges or turnable flanges.
Loose flanges are not welded onto
the expansion joint, but either flared
onto a bellow or fixed behind a
welded collar or ring.
This feature allows the flanges to turn
around its axis, and make it easy to fit
into the pipe system.
The ring or welded collar is acting as
a raised face or sealing surface, and
these two types of flanges are,
depending on the diameter, used up
to 25 BarG pressure. For use at
higher pressures, welded flanges are
preferred. Turnable flanges are a very
powerful solution to counter flanges,
which are out of line and can be
easier to install when compared with
welded flanges.
Collar
A collar rim is practical addition for the
bellows end tangents which are flared
over a flange, thereby forming a rim
which holds the flange in position. It is
a very cost efficient solution, saving
welding time, with the flaring process
being performed quicker than through
welding.
Collar ring
A collar ring is a ring that is welded
onto each end tangents of the
bellows. The collar ring adds rigidity
to a flanged connection and through
which it can be used for higher
pressure applications.
Welded collar
A welded collar can be made of angle
bar or as a standard fitting. The
welded collar is welded to the bellows
end tangents with the flange behind
the collar. Depending on the
thickness and shape of the collar it
can be used in high pressure
applications.
Cover and insulation
If the external protection of the bellow
is necessary, a cover can be
mounted. The cover protects the
bellow from dust particles from the
surroundings, against mechanical
damage and/or external flow.
Furthermore, the cover is a good
base for external insulation for
preventing the insulation from packing
up between the bellows convolutions.
Insulation of expansion joints is often
undertaken in applications operating
at higher temperature in order to
prevent heat loss.
Tie rods
Tie rods on an expansion joint help to
restrain the pressure thrust forces,
while simultaneously allowing lateral
deflection and axial compression. The
size and quantity of tie rods is
determined by the magnitude of the
pressure thrust forces. Expansion
joints with only two tie rods allow
angular rotation in cases, where the
tie rods are orientated 90 degrees
opposite to the direction of the
rotation.
The installation of restrained
expansion joints do not require fix
points and pressure thrust forces are
not transferred onto external
equipment.
Hinges
Expansion joints with hinges allow
angular movement in a single plane
with the pressure thrust forces being
restrained from the bellow. Hinges
prevent the bellows from axial
deflection and are ideally used in set
for lateral deflection or in a three-
hinged constellation for multi plane
axial movements. As the hinges
restrain pressure thrust forces, only
guides are needed to control the
movements.
FITTINGS
Gimbals
A gimbal expansion joint contains two
sets of hinges, which are connected
to a central gimbal ring/box by 4 pins
and thereby permits angular rotation
in any plane. The pair of hinges
restrains the unit from transferring
pressure thrust forces to external
equipment.
Gimbal expansion joints can be
installed in sets to absorb large
movements.
Pantographic linkage
A pantographic linkage is installed on
expansion joints with double- or
multiple bellows. The pantographic
linkage is a type of accessory, which
is used to distribute large axial
movements equally between two or
more bellows. The pantograph can
also be designed to allow lateral
movement and support the weight of
the intermediate pipe section. The key
function of a pantographic linkage is
to equally distribute the total
movements and prevent a fatigue
overload of the bellows.

INNER SLEEVE
Inner sleeves are used for the internal
protection of the bellow. They can be
used in the following cases:
l Protecting the bellow from
an abrasive media.
l Protecting the bellow from high
flow velocity.
l Preventing particles and solid
objects from settling between the
convolutions.
Information concerning flow velocity
and media is very important when
designing expansion joints.
It is important to specify the flow
velocity and media on all inquiries.
Why are inner sleeves important?
An expansion joint is often introduced
into a pipe system in order to
introduce a flexible element for the
compensation of thermal expansion
with the consequence being the
stress relief of the pipe system. In
order to achieve this flexibility, the
expansion joint is usually produced
with a material thickness, which is
considerably less than the rest of the
components. This however results in
making the expansion joint vulnerable
in many areas that is why in certain
applications, it is necessary to mount
a protective inner sleeve, which can
ensure the integrity of the expansion
joint. A large number of factors
influence the requirement of inner
sleeves for use in an application.
Shape of media and flow velocity
The type of media i.e. gas or liquid,
along with the flow velocity and
density of the media is of great
significance to the design of the
expansion joint, since a liquid with the
same flow velocity as a gas has a
greater impulse and thus requires
more from the construction.
High flow velocity can result in
flow-induced vibrations in the bellow,
which can considerably shorten its
lifetime or in a worst case, cause
damage to the expansion joint. An
inner sleeve can solve this.
The flow velocity has a direct effect on
the dimensions of the inner sleeve.
The higher the flow velocity is, the
thicker the inner sleeve must be.
Here the length of the inner sleeve
also plays a part, since a long inner
sleeve must be thicker than a short
inner sleeve to provide sufficient
rigidity.
The effect of the flow velocity on the
expansion joint is further complicated
because the up-stream shape of the
inner sleeve that has a great influence
on how non-turbulent or turbulent the
flow through the expansion joint is. If
there are pipe bends, valves or the
like in a distance of up to 10 times the
nominal diameter of the inner sleeve,
the flow will be turbulent. The
informed flow velocity can in actual
fact be multiplied by a factor of 4,
when calculating the thickness of the
inner sleeve.
Abrasive media and corrosion
Since the bellow is normally made of
materials in considerably thinner
layers than the rest of the pipe
components, abrasive media can be
problematic, as the flow of the media
can rapidly “wear out” the thin plies of
the steel bellow. In such a situation, a
relatively strong inner sleeve should
be used for protection of the bellow.
In cases featuring extremely abrasive
media, Belman prefers to use inner
sleeves made of Hardox steel. The
composition of the media and the
particle content is important for the
selection of the material for an inner
sleeve.
The material must be corrosion
resistant during given operating
conditions and resistant to
possible condensates, which can
form during the down time of the
system.
Packing up in the convolutions
In addition to its protective role
against abrasion and high flow
velocity, it can further protect against
a media packing up between each
convolution.
In some applications, the medium can
be sticky, solid or of a composition
which creates a risk of the media
clotting in the convolutions. This will
reduce the functionality of the
expansion joint that can result in
failure of the bellow. This risk in some
situations is alleviated by the
mounting of an inner sleeve.
Temperature and loss of pressure
The temperature has no critical
influence on whether an inner sleeve
is required or not. The temperature
influences the design of the inner
sleeve due to the materials strength
properties at specified design
pressures. At design temperatures in
excess of 150°C, the elevated
temperatures are compensated by a
minor addition in the inner sleeve wall
thickness. Some applications require
a minimum of pressure loss through
the expansion joint and in such cases
the inner sleeve can also be an
advantage. A flow over an
unprotected bellow always creates
some pressure loss; this is because
the “roughness” of the convolutions
generates turbulence. This pressure
loss can be reduced by installing an
inner sleeve.
Specifications for inner sleeves
We can calculate under which
circumstances an inner sleeve is
required. To support this calculation,
we need as much information as
possible but we must receive the
following information as a minimum:
l Media composition (whether the
media is gas or liquid – and the
density).
l Flow velocity.
l Whether the media contains
particles, which can be abrasive.
l Creation of possible condensates
during shutdown.
l Information concerning the
up-stream condition for the pipe
system.
Requirement for an inner sleeve
The question of whether an inner
sleeve is required or not can be
determined by the guidelines in the
diagram below.
If the values in the diagram are
exceeded, inserting an inner sleeve is
to be recommended. Flow velocities
values higher than that given below
can induce resonant vibrations on the
bellows convolutions, which may result
in the destruction of the bellows.

INSULATION
Expansion joints can be insulated in
various ways and can be insulated
internally as well as externally.
Internal insulation is usually carried
out in order to lower the temperature
of the bellow/expansion joint to a
temperature range where design of
this vital part can be more suitable
(e.g. below the materials creep range).
Insulation can also be done for safety
reasons in order to protect the outer
surroundings from an expansion joint
surface temperature that is too high.
For example, in a carbon black
manufacturer’s application, where the
medium had a particularly high
temperature of 1000°C, the customer
chose to insulate the expansion joint
internally. By insulating the expansion
joint, its surface temperature was
reduced to 90°C.
Insulation can also be done in order
to reduce the heat loss of the
medium, or due to an increased
efficiency of the pipe system. In case
of sluggish mediums with a relatively
high viscosity, insulated expansion
joints will help maintaining the media
viscosity. However, insulation by itself
may be insufficient, as it will only
reduce the rate of the heat loss.
In systems where the existing heat
may not be sufficient to prevent the
medium from cooling, the medium
may settle in the convolutions and
impair the functionality of the
expansion joint. In such cases, the
best solution can be a chamber
expansion joint. Insulation can be
carried out using ceramic wool, which
is available in many different types to
suit a range of applications. Insulation
can also be provided through the
addition of a lining whereby the
expansion joint is insulated with
concrete.
When insulating an expansion joint, it
is necessary to consider the
characteristics of the insulation
material. With certain insulating
materials there is a risk of packing up,
therefore the material must not be
placed between the convolutions of
the bellows, as this impairs the
bellows functionality. In such cases, it
is important to prevent the insulating
material from settling between the
convolutions. For example by the
fitting of a shell/cover over the
convolutions, from which the insula-
tion material can be mounted around.
Insulation can be provided in many
ways, on both the outside and the
inside of the expansion joint.

PRESSURE THRUST
Force in a perpendicular direction or
applied normally on an area is called
thrust. Pressure thrust force is the
most essential force encountered in
pressurised pipe systems and if
ignored or incorrectly calculated, it
can have a major impact on the pipe
system or the surrounding hardware.
Expansion joints are intended to
absorb pipe expansion and to
withstand pressure forces and
movements. However unrestrained
expansion joints also transfer forces,
where the most important factors are
the bellows spring rate and pressure
thrust. Pressure thrust force acts
Fp = P x A
Where:
Fp = Pressure thrust force [N]
P = Pressure [bar]
A = Bellows mean diameter
area [mm2
]
Unrestrained
With unrestrained expansion joints,
both spring rates and pressure thrust
forces occur, and the pressure thrust
is often greater than the spring rates.
This type of expansion joint always
requires fix points or a foundation,
which is rigid enough to carry the
differently depending on whether the
pipe system is anchored and guided
or floating. If unrestrained axial
expansion joints are used, pressure
thrust force must be obtained at both
ends of the pipe system by fix points.
Single bellows subjected to an axial
movement could be simplified as an
hydraulic cylinder with a spring inside.
The spring represents the axial spring
rate of the bellows, and the hydraulic
piston represents the effect of the
pressure thrust which the expansion
joint can exert on the piping fix points
or pressure thrust restraints.
The area of the hydraulic cylinder
loads. This often results in a high
financial cost.
Restrained
Alternatively, the reaction force from
the bellows can be eliminated by
using restrained expansion joints.
Restrained expansion joints are
restrained by using tie-rods, hinge- or
gimbal systems over the flexible part.
This hardware obtains all pressure
thrust forces and makes the
expansion joint behave like a straight
pipe, the only load to consider is the
spring rate.
Restrained expansion joints can be a
very cost effective solution in many
would be effective area of the bellows.
Expansion joints normally have a
cross-sectional area, which is slightly
larger than the pipe diameter due to the
height of the convolutions. This is a
critical detail to take into consideration
when designing pipe systems and fix
points. The effective cross section can
be illustrated by the sketch below.
Pressure thrust force is calculated by
the product of the bellows mean
diameter multiplied by the maximum
line pressure as follows:
(always base the calculation on the
maximum pressure that occurs, usually
the test pressure)
situations, where costly fix points and
foundation work is required.
Pressure balanced
Where large diameters, high pressure,
or fix points are impractical due to
economic or structural reasons, a
pressure balanced expansion joint
can be a powerful solution to a
challenging design problem.
This type of expansion joint is
basically the same as a restrained
unit, but in which the pressure thrust
is compensated by larger balancing
bellows or a balancing chamber.

SPRING RATES
Flexible bellows can be compared to
a steel spring in its flexible motion.
The spring rate is an expression of the
force required to compress or extend
the bellows, or alternately its
resistance to deflect, which is another
factor to take into account when
calculating loads on fix points.
The bellows spring rate depends
particularly on the bellows geometry
and especially the bellows ply
thickness, the number of plies,
convolution geometry and materials.
Secondly, the actual working
temperature of the bellows also
influences the spring rate, as the steel
loses its rigidity at elevated tempera-
tures. Therefore, the specified design
temperature should be as close to the
maximum as possible, without being
overstated.
The magnitude of the spring force is
determined by the expansion joint
spring constant and the amount of
movement of the expansion joint,
which is calculated as follows:
F = K x X
Where:
F = Force [N]
K = Spring rate [N/mm]
X = Movement [mm]
The bellows will have a spring back
effect when the movement range is
within the elastic range of the
material. But an excessive movement
range will result in a permanent
deformation of the bellows, especially
when the movement range is entering
into the plastic range of the bellows
material.
Belman specifies spring rates
calculated in full in accordance with
the specified code. The majority of
tests have verified actual spring rates
to have been around 30% less than
calculated. When a particular
application requires a more precise
specification of the bellows working
spring rate, the customer should
specify this to Belman. In special
projects, Belman will determine if a
prototype testing is necessary to
specify the precise load vs. deflection
characteristics of a particular bellows
design.
STABILITY
Expansion joints have to be flexible to
absorb movements but at the same
time they require the strength and
stability to transfer any specified fluid
at a given pressure and temperature.
In case an expansion joint is exposed
to an excessive internal pressure, the
bellows will show instability. Instability
can occur in two modes, column
instability or in-plane deformation
(squirm) of the convolution side wall.
Column instability applies only to
bellows with internal pressure.
Column instability (or squirm) is the
phenomena whereby the centerline of
a straight bellows develops a side-
ways or lateral bow. Column instability
affects the bellows as a whole, while
in-plane or squirm deformation affects
only one or more convolutions
individually. In-plane instability, called
also local instability or squirm, occurs
in bellows with relative small ratio of
length and diameter, and is defined as
slipping or twisting the plane of one or
several convolutions against each
parallel convolution.
The critical pressure at which this
instability occurs is a direct function of
the diameter and spring rate, and an
inverse function of the length.
A simple way to imagine this, is to
remember that the bellow is a cylinder
of given volume. Internal pressure
tries to increase a vessel’s volume.
Since a bellow is flexible in the axial
direction, it can increase its volume by
increasing the length of its centerline.
With the ends fixed, it tries so by
simulating the appearance of a
buckling column.
Column instability In-plane instability

419
Externally pressurised bellows should
not be confused with bellows used for
vacuum. With vacuum designed
bellows only the inner ply is
considered for pressure and stability.
The design for externally pressurised
expansion joints has the advantage of
absorbing large movements at low
adjusting forces. It is possible to add
a high number of convolutions
EXTERNAL PRESSURE
because the column stability such as
squirm, can be eliminated due to its
design.
Depending on the role the expansion
joint has to perform, there are different
designs that can be chosen.
When produced with an external
cover, it is easy to drain, and this
design also protects the bellow from
possible damage.

Materials expand or contract when
subjected to changes in temperature.
Most materials expand when they are
heated and contract when they are
cooled. In scientific terms, heat is a
form of kinetic energy and also called
molecular translational energy due to
motion of molecules. Thermal
expansion occurs due to the
molecules moving faster when heated
more than their average temperature.
When the molecules move faster as a
result of the added heat, they occupy
more space. This causes an increase
in the material size.
The linear thermal expansion of metal
components referring to a tempera-
ture range, can be determined by
means of the material-related
expansion coefficient:

VIBRATIONS
Where machines, pumps or similar
rotating aggregates are present, there
will be vibrations. Vibrations can occur
in different frequencies and ampli-
tudes creating noise (high frequency)
or leading to material fatigue and
damage. When the vibrations result in
damage, the resulting shutdown and
repair work can be very costly.
Expansion joints designed for
vibration absorption prevent these
failures and absorb or even remove
the noise.
Connections
Normally standard flange connections
are used, but custom designs can
also be provided for solving difficult
and complex installations.
The choice of material and design of
vibration absorbing expansion joints
(vibration absorbers) depends on a
number of variables, such as the
media, pressure and temperature of
the application. The operating
pressure is also taken to calculate
the reactive force.
Operating pressure releases the axial
reaction force, when an expansion
joint without restraints is used and
places direct force on supports, walls
and/or aggregates near to the
expansion joint. This can lead to the
displacement or tilting of the aggre-
gate, depending on the size of the
force. Wherever expansion joints are
used, it is important to understand
the movement that the different
expansion joints can absorb. There-
fore, the placement of pipe supports
and the selection of the correct
expansion joint is very important.
The vibration frequencies should be
outside the range of the natural
frequencies of the expansion joints.
When used for noise insulation, the
natural frequency should be lower
than the noise frequencies. When
used for low frequency vibrations, it
should be higher (and far away) to
have the best-dampening effect. We
can calculate these natural frequen-
cies upon the customer's request.
Vibrations created during start up and
shutdown can in general be ignored
when designing the expansion joint,
because they typically occur only for
very short time period. However,
pressure shocks cannot be ignored,
as they can damage the expansion
joints and should be eliminated.
The vibration created from the
medium that also makes the pipe
system vibrate, will not be absorbed
from expansion joints, those
vibrations can instead be controlled
from viscous dampers.
Guides and fix points
Where the pipe from the vibrating
aggregates are connected to the
expansion joint, the support shall be
placed directly after the expansion
joints. But be aware that these
supports are not connected to the
vibrating foundation. Supports, in the
form of fix points or guides, should be
properly sized to control the reaction
and adjusting forces.
When lateral thermal expansion is to
be absorbed, a guide should be used.
Restrained expansion joints with
lateral movements are used when the
operation pressure is very high that an
axial expansion joint is no longer
suitable. However, under such
conditions, it is important to under-
stand if the vibrations are acting only
in one plane perpendicular to the
connecting axis, or in a 3-dimensional
plane where the movements are in all
directions. For vibrations in one plane,
a single expansion joint with
spherically supported tie rods with
flexibility in all directions of plane, is
sufficient.
For 3-dimensional movements, a
second expansion joint has to be
installed perpendicular to the first one.
This second expansion joint can be of
either lateral or angular design,
depending on the other parameters
such as amplitudes or thermal
expansion. Using an angular design
as a second expansion joint, it should
be taken into account how the two
expansions joints can work
together. The pipe bend has to be
able to make tilting motions and the
lateral design should permit that. If
a lateral design is used as a second
expansion joint, it should be
mounted at an angle of 90° to the
first expansion joint.
Pressure balanced
Pressure balanced corner relief
expansion joints can be the
optimum solution to control
3-dimentional vibrations in all
directions, when the vibrating mass
is smaller. However, when com-
pared to the lateral and angular
designs, this design is also more
expensive.
Noise reducing expansion joints
When using a lateral design as
described, insulation is not enough to
prevent noise. The noise can be
transmitted through the fix points or tie
rods, even by using multi-ply bellow.
Vibrations absorbers for lateral expan-
sion joints are provided with damping
washers made of stainless steel wire.
These washers are temperature- and
aging-resistant. The design of which
ensures that they retain their shape
and technical characteristics for
practically their entire working lifetime.
Vibration absorbers can also be
special and customised designs.

Choosing the best solution with the
correct expansion joint is important.
Expansion joints, used for the
compensation of misalignments in the
piping system can, in theory, work as
a one-time movement which should
have no impact on the service life. In
practice, there is a high risk of
deposition. Deposition could lead to
the blockage of the normal move-
ments and cause an early failure of
the expansion joint.
The risk is highest for short axial
expansion joints that absorb lateral
movements.
When using expansion joints for
subsidence damage and the
correction of inaccuracies in founda-
tions, it can be considered a one-time
movement. The expansion joint can
even absorb very high deformation
without having leaks. However, if it is
used for controlling displacements
when filling or emptying tanks, then
the design has to deal with stress
cycles and be calculated in the same
way as a normal expansion joint.
Expansion joints can also be used as
a mounting or dismounting space for
items such as valves. To ensure the
optimal design, these expansion joints
should be able to withstand large
movements without the convolutions
being blocked.
SETTLEMENT TORSION
Torsion acting in or around the
longitudinal axis of the bellow should
be avoided. In general, this is due to
the extremely high shear stresses
produced. When such forces exist in
the system, it is advisable to deploy
special hardware to limit its influence.
Hinges and gimbals could be
included in the possible solutions.
Illustration of torsion

426 427
Corrosion can be defined as an un-
desirable chemical or electrochemical
damage to the material.
Safety-related corrosion is also an
important factor. Types of corrosion
such as stress corrosion, intergranular
corrosion, crevice corrosion and
corrosion fatigue can occur fast and
lead to the destruction of a steel
construction.
The corrosion resistance of stainless
steel depends on the alloy and the
oxide film that covers the surface of
the material. Different media can
break this film down and cause
different kinds of corrosive attacks.
Typically, corrosive attacks seen on
expansion joints are:
Corrosion fatigue
Fatigues are frail and the cracks are
often opposite grained as with stress
corrosion cracking but not branched.
Corrosion fatigue results from a
simultaneous influence of dynamic
influences and corrosion. Most
corrosion damages that involve
spalling or corrosion flakes have an
element of corrosion fatigue to them.
Generally, the expansion joint is
designed so that corrosion fatigue
should not occur.
Intergranular corrosion
Intergranular corrosion is – as the
name implies – a kind of corrosion
that follows the grain boundaries,
which have a relatively low chromium
content. Intergranular corrosion can
occur if the steel has been heated for
too long at temperatures between
550ºC and 850ºC. For this reason,
welding must be performed with low
heat input and preheating must never
be used. Preheating is the technical
increasing of the heat input. It occurs
if the steel is sensitised with the steel
being exposed to heat treatment, as
the chromium content in the grain
boundaries becomes used up.
Therefore, the chromium is no longer
available for the further protection
against corrosion. Sensitisation can
happen if the steel contains too much
carbon (C), which is planned to be
less than 0,03%, and is heated to the
temperature area 550-850ºC. At
these temperatures, the carbon will
collect in the grain boundaries – the C
atoms diffuse into the grain bounda-
ries – where they will react with Cr
with the formation of chromium
carbides (CrC). The result will be a
quite narrow zone alongside the grain
boundaries, where the content of
chromium has become too low (less
than 12% Cr) for the resistance
against corrosion. The physical
characteristics of the steel are not
significantly influenced if the
necessary precautions against
intergranular corrosion are taken.
Intergranular corrosion is easiest to
avoid when specifying a carbon
content lower than 0,03% C (and
likewise a specific test against
intergranular corrosion can be
requested in the material certificate)
and an eventually stabilisation of the
steel with titanium (or niobium).
Stress corrosion cracking
Stress corrosion cracking is re-
cognisable because of the charac-
teristic cracking, where side branch
occurs in both the material surface as
well as in the depth. Stress corrosion
CORROSION
cracking can occur if austenitic
stainless steel is exposed to a
combination of tensile stress,
increased temperatures and an
environment that contains chlorides
(or other chemicals).
Stress corrosion cracking is together
with crevice corrosion, the most
common type affecting expansion
joints. Stress corrosion cracking
occurs on the expansion joint
because of stresses in the bellow
caused by larger movements than
which the expansion joint is designed
for. Likewise, a high operating
pressure can be the reason.
Stress corrosion cracking can be
avoided by removing one or more of
these factors but in practice this is
seldom possible. The only option is
the use of a higher alloyed steel/mate-
rial. In this regard, the nickel content
is the most relevant issue.
Pitting corrosion
Pitting corrosion is localised corrosion
and is characterised by small discreet
holes on the surface of the steel.
Pitting corrosion occurs if the oxide
film is too weak to resist the environ-
ment in which the steel is exposed.
This can result in the local destruction
of the oxide film that is not capable of
rebuilding itself, after which the
corrosion attack continues. The
attack from pitting corrosion will
normally look rather innocent on the
surface; but underneath the corrosion
can extend to a significant size.
Crevice corrosion
Crevice corrosion occurs in narrow,
liquid-charged splits, where the
oxygen is quickly used up, and for
that reason, the passitivity cannot be
maintained.
Crevice corrosion is closely related to
pitting corrosion. In narrow slits like
overlaps- and FL-joints, the
concentration of aggressive media is
possible, leading to a breakdown of
the passive film. Because of the lack
of oxidization of the oxide film, pitting
corrosion continues.
A variant of crevice corrosion can
occur under incrustation in maritime
environment.
This kind of corrosion is often seen on
COR R OS I ON
expansion joints, as assemblies
between connection ends (e.g. a
flange) and bellow can result in the
formation of gaps or crevices. In this
crevice corrosion can occur.
Pitting corrosion and crevice
corrosion can be avoided by:
1. Selection of the appropriate steel
type, which is sufficiently high
alloyed – and therefore can resist
the environmental conditions
2. Avoiding gaps
3. Be meticulous in the avoidance
of contamination of the stainless
steel. Minor damages may be
alleviated by pickling.
Corrosion caused by turbulence
This kind of corrosion is very special
and is rarely seen. Even so, attention
to this kind of corrosion should be
paid. If the flow rate exceeds 20 m/s,
that can constitute a potential risk.
Therefore, in cases where the flow
rate exceeds 20 m/s, we recommend
to contact Belman. We would
welcome the opportunity to advise
you on this very special corrosion
type.

429
Corrosion can be defined as the
gradual destruction of materials
through a chemical reaction with their
environment. There are many different
types of corrosion, the most impor-
tant corrosion forms for ferrous and
non-ferrous materials were described
in the previous pages.
How to avoid
corrosion on the bellow
Corrosion can be avoided by the
appropriate selection of materials for
the bellow. The application, the
media, the operating environment,
customer requirements and/or other
factors determine the choice of
material for the bellow. Sometimes
demanding projects require other
alternative kinds of corrosion protec-
tion for the expansion joint. We offer
the following alternative kinds of
protection against corrosion which
are shown in the following pages.
How to avoid corrosion
on the steel components
Corrosion on carbon steel expansion
joint components such as
welding ends, flanges, hinges,
gimbals, intermediate pipes, covers
etc. are avoided via the appropriate
material selection and/or surface
treatment.
Material selection involves the
selection of a material which is
resistant to corrosion; this may be in
the form of a high alloy steel type.
Usually surface treatment is a coating
such as a primer which is specified by
the client.
This material selection and/or surface
treatment are done according to
customer requirement, project
specification and/or according to
application requirements.

PTFE COATING
PTFE-coated expansion joints are an
alternative solution for those applica-
tions in which steel expansion joints
are not considered as the optimal
choice. This could be due to an
aggressive medium or other factors
which make it necessary to use a high
alloy bellow material, resulting in the
total solution becoming more
expensive. In such cases, PTFE can
be a very good alternative – both from
a technical and an economic
perspective.
Compared to most common steel
and rubber material types, the cost of
PTFE is rather low. However, when
compared to titanium and similar high
alloy steel materials, it is proven to be
considerably cheaper. PTFE bellows
are often used in the chemical and
paper industries, especially in
applications with aggressive mediums
such as chlorine. These mediums are
corrosive against common steel types
and even most of nickel alloys. The
only possibility is therefore the
selection of high cost titanium or
other high alloy materials. For this
reason, PTFE is often chosen due to
its cost advantage and also because
of its good resistance against many
medias.
The PTFE coating is characterised by
good corrosion protection against
aggressive mediums. In addition, the
PTFE material is also wear resistant.
COR R OS I ON
Expansion joints can be coated with
an inner 550-1500 μm PTFE coating
and – if the intended use requires this
– the same PTFE coating can also be
applied to the seal surfaces.
Temperature
This type of coating can be used for
applications with a temperature of up
to 150°C.
Pressure
Depending on the diameter, PTFE
bellows are suitable for a pressure in
excess of 13 barG.

432 433
TANTALUM COATING
In situations where the pipe system/
plant has a highly aggressive medium
and aggressive operating conditions,
tantalum is a possible solution instead
of special metals. Tantalum brings an
increased corrosion resistance and
faster delivery. By choosing an
expansion joint with a tantalum
surface, a better utilisation of the
product can be achieved. The bellows
can achieve a higher resistance to
corrosion, surpassing that of the
special metals (such as titanium,
Hastelloy etc.), while simultaneously
preserving the steels ductility.
Tantalum coating is unique in the
sense that the chemical process
takes place at a high temperature,
and the tantalum metal is partly
alloyed into the stainless bellows and
a 50 µm tantalum layer is precipitated.
Thus, mechanical characteristics
equivalent to those of stainless steel
are maintained and they are signifi-
cantly better than bellows manufac-
tured with a loose tantalum liner or
from solid tantalum metal.
Operating reliability
Generally, tantalum components
achieve a longer service life and thus
provide a better operating reliability
than their alternatives (PTFE, special
metals such as Hastelloy).
Some plant owners still continue to
choose their current solutions and
accept the need for regular replace-
ments. However, a tantalum solution
can significantly minimise the
resources needed for replacement
and the uncertainty/worries of
breakdowns. For instance, on
thick-walled valves it may be
acceptable that corrosion affects the
metal thickness, but on bellows with a
low metal thickness, this can be very
COR R OS I ON
problematic for the performance and
the service life.
The alternatives
For aggressive mediums, steel
expansion joints coated with PTFE are
usually used. The aggressiveness of
the medium determines the degree of
alloying of the steel. Usually, special
metals (e.g. Hastelloy) are used. In
many cases, this is sufficient. The risk
arises when quiet corrosion occurs
due to attrition/damage of the PTFE
coating, allowing the medium access
to the steel.
Possible applications
Tantalum coated expansion joints
have many possible applications and
are well-suited for installation in hot
and acidic environments with elevated
temperatures. At 150°C tantalum is
resistant to most chemicals and
mixtures of chemicals no matter the
concentration; this includes wet
gases, acidic aqueous solutions as
well as high concentrations of nitric,
hydrochloric and sulphuric acid.
The most important exceptions
concern hydrogen fluoride, fluorides
and concentrated bases (pH13). At
150–250°C, there are limitations in
the concentration ratio or mixtures.
Above 300°C, tantalum will oxidize in
air and its application is reduced to
metalfuses under inert atmosphere.
Such conditions are often present in
the chemical, oil and gas, energy and
the pharmaceutical industry.
However, the need does not exist in
all of the above mentioned industries.
Tantalum is, therefore, suited primarily
for customers who have problems
with highly corrosive mediums and
who experience problems with
operating reliability and the service
life/performance of their components.
Exception
Tantalum coated expansion joints
should not be used in strong basic
environments (pH13); in such cases,
stainless materials or pure nickel can
provide a better and lower cost
solution. Tantalum, however, is
applicable for ammonium hydroxide
and hypochlorite solutions and other
less strong basic environments.
Should tantalum be considered as a
possible solution for you, we are
pleased to assist on assessing how
the tantalum treatment will affect the
design of the expansion joint (such as
general dimensioning, spring rates,
service life/fatigue, etc.).
If basic cleaning is needed, 2% KOH
up to 60°C can be used.
Tantalum vs. other steels
Tantalum is very corrosion resistant
and can increase the service life by
up to 10 times compared to the
special steels. Tantalum is one of the
few metals that are resistant to aqua
regia. Compared to stainless steel,
treatment with tantalum gives the
bellows a grey surface. Both the
bellows and any guide pipes can be
treated with tantalum.
Tantalum coated expansion joints are
customised solutions and are available
in sizes up to DN 350 and in
installation lengths up to 700 mm.
Tantalum layer
The tantalum layer will as standard be
50 µm but it can be increased to up to
200 µm.
