Some facts about LOGSTOR Industry
• Established in 1992
• Production in Denmark
• 35 employees
• Local representation in
– UK
– Germany
– Sweden
– Benelux
– Turkey
– and in many other European
countries through District
Heating sales companies
• World wide export!

The concept
Carrier pipe to client specification or delivered by the client!
Carrier pipe
• Carbon steel
• Stainless steel
• Plastic
• Copper etc.
Insulation
• Polyurethane
foam (PUR)
Jacket pipe
• High Density
Polyethylene
(HDPE)
• Spiro jacket
(galvanized,
aluzinc, SS etc.)

Carrier pipe
• Supplied standard lengths of 6 or 12 m
– or according to client specification
• Standard steel pipes from DN15 to DN1200
• The pipes are supplied with 150 mm. exposed ends as standard
• The medium decides the carrier pipe material
Typical applications Steam

Insulation
• Polyurethane foam (PUR)
– Made of polyol and
isocyanate
– Free of chlorides!
• 5 series of insulation to meet
all technical and economical
demands!
– The choice of a thicker
insulation can be
advantageous in the long
run...
• It meets the requirements of
EN253

Insulation
• Density: min. 60 kg/m3
• Cell structure: min. 88%
closed cells
• Compressive strength 10%
deformation: min. 0,3 N/mm2
• A low heat conductivity:
– 0,027 W/mK (+50°C)
– 0,022 W/mK (-20°C)
• For normal applications, the
pipe assembly should have a
life of at least 30 years!
Low heat conductivity in unaged conditions...

Jacket pipe
• HDPE in black or white
– 100% watertight!
– Impact resistant
– Salt and chemical resistant
– Hygienic
– Anti-corrosive
– The black HDPE is UV
resistant
• The HDPE is approved to fire
classification NT fire 036
(classification 3)

Hygienic design
• The smooth surfaces of both
pipes and joints are just as
easy to clean as a stainless
steel surface
• The HDPE tolerates cleaning
with high pressure jets!

Intelligent pipes
Alarm wires for moisture
detection. Resistance or
impedance
Leak detection for Oils
and chemicals
Heat tracer for frost
protection or heat
maintenance

Pipe production - traditional
1. The foam is injected
2. The PUR foam expands to
fill the pipe
3. After trimming the ends...
4. It is finished!

Pipe production – traditional
LOGSTOR invented it in 1960...!

Product range
The 3 systems
Low temperature (LT) ÷200°C - ÷60°C
Normal temperature (NT) ÷60°C - +140°C
High temperature (HT) +140°C - +250°C

Low Temperature System
• Operating temperatures
– from -200°C to -60°C
• Insulation serie 5
• Only freely suspended
systems
• The system is applicable for
media such as:
– Liquid nitrogen, liquid argon,
liquid oxygen etc.

Normal Temperature System
• Operating temperature
– from -60°C to +140°C
• Insulation serie 1-4
• Freely suspended or directly
buried systems
media such as:
– Ammonia, glycol, food &
beverage products,
condensate, oil etc.

High Temperature System
• Operating temperature
– from +140°C to +250°C
• Freely suspended or directly
buried systems
media such as:
– hot water, hot oil, steam etc.
etc

High Temperature System
• The insulation consists of a
combination of PUR foam and
mineral wool
• The insulation system is
supplied in 2 standard
versions
– For medium temperatures of
max. +210°C and max.
+250°C
Mineral wool
PUR foam

Above ground systems
• The pipe design is a bonded
system
• It is supported outside the
coating
– no thermal bridges!
• It is robust and may be used
as walkways
• Space saving solution in e.g.
pipe racks
Why insulate afterwards, when you can do it
much better upfront?

Underground systems
• It is water and diffusion tight!
• It is robust
• The jacket pipes are held in
place by soil friction
• Don’t necessite a cement wall
trench

Underground systems
• Any movement caused by
temperature change is
absorbed within the system
itself!
• The movements are absorbed
by expansion-absorbing
elements
– i.e. L, Z or U bends and axial
compensators

Fittings and joints
Solution 1
• Pre-insulated pipes and
fittings
Solution 2
• Pre-insulated pipes and heat
shrinkable joints

Flexible joints with half-shells
Straight joints
0 - 15O
Dim. ø90–630 mm.
Bend joints
15 - 90O
Dim. ø90–315 mm.
T-joints
Main pipe dim. ø90–450 mm.
Branch pipe dim. ø66-180 mm.

The sleeves
• Cross-linked Polyethylene
(PEX)
• They are remarkably flexible
and bendable!
• They are 100% water tight!
• They have the same
mechanical strength as the
rest of the pipe system
• They tolerate over heating,
does not stress crack and
stress release
It’s unique LOGSTOR technology!

Installing the flexible joints

Pre-insulated fittings
• Everything is possible!
– Bends, Tee´s, anchors,
valves, spools and customer
designs
• They are watertight and
robust
• Continuous jackets without
penetrations
• Simple and quick installation
on site!

Pipe supports
• The type depends on the pipe
layout
• Available in electroplated or
stainless steel
• The support is fixed on the
jacket - no thermal bridges!

How to optimize the investment?

10 good reasons
1. Outstanding insulation
quality!
• heat loss is up to 40% less
than in a corresponding
system with traditional
insulation
2. Supports are fitted outside
the casing
• no thermal bridges
3. 100% water tight!
4. Effective corrosion
resistance
5. High level of hygiene

10 good reasons
6. High mechanical strength
• you may walk on it!
7. Reduced installing costs
• quick installation of pre-
insulated pipes
8. Minimal maintenance costs
9. Low operating costs throughout
the lifetime of the pipe system
10.Jackets in black or white HDPE
• the black is UV resistant
