Borosilicate glass represents unmatched standardized glass for construction of plant
and piping in the chemical, dyestuff, food pharmaceutical, petrochemical industries. Its
steadily growing use is due to many advantages over conventional materials.
1) The best way to clean a screw and barrel is to remove the screw from the machine and clean it outside using brass tools and stearic acid rather than applying direct heat, which can damage the metal.
2) To purge the system, use HDPE plastic at 200C while slowly rotating the screw until the extrudate fully changes from the processing resin to HDPE.
3) Clean the screw using brass tools and stearic acid while exposing sections, then clean the barrel bore using a wire brush coated in copper gauze and stearic acid.
The document discusses hidden threats in austenitic stainless steel piping used in a natural gas extraction plant. Stress corrosion cracking was found in welded regions of reinforcing pads and wear pads due to the presence of chlorides, causing severe cracking and leaks. To restore integrity, vessels were replaced and affected lines were repaired. A repair option involving replacing cracked original wear pads with larger cold-bonded stainless steel wear pads was chosen and implemented.
The document describes the various steel treatment and painting processes used on Atlas Copco generators and light towers to protect them from corrosion when exposed to outdoor environments. Different components receive different treatments based on their exposure and importance. All steel components receive a galvanization treatment before further treatments and painting. The canopy receives powder coating, while critical components and the base frame undergo nitrogen laser cutting and cataphoresis before final painting. These treatments help provide long-term corrosion protection and extend the life of components.
This document discusses recommended barrel temperature profiles for barrier type extrusion screws. It recommends:
1) Setting the die and adapter zones to the resin manufacturer's recommended melt temperature.
2) Setting the feed throat section 10-20°F warmer than ambient to preheat the material without causing bridging.
3) Installing screw cooling in the feed section to reduce friction and optimize solids conveying.
4) Evenly spacing the remaining zone temperatures between the feed and metering sections to gradually melt the resin using increased energy input.
Starting temperature profiles are provided for example resins to process them less stressfully and reduce wear on the screw and barrel.
The material handling of the feedstock is a very critical part of the extrusion process. If the feedstock is not introduced to the feedsection of screw in a smooth and uniform matter, then the likelihood of a stable and consistent output is unlikely. This is the reason why it is very important that if regrind is added to the virgin feedstock, it must be done very consistently and uniformly. It should also be mentioned here that a very important part of the extrusion equipment is the hopper and feedthroat section. If the hopper and feedthroat sections are not designed properly, inconsistent material flow to the screw can take place. For example, if the conical section of the hopper (see figure) does not have the proper transition, the resin will not flow smoothly into the feedthroat of the extruder.

IRJET- Design Modifications in Cryogenic Pressure Relief Valve to Elimina...IRJET Journal
This document discusses modifications made to cryogenic pressure relief valves to eliminate seat leakage. Cryogenic liquids experience large volumetric expansion at low temperatures, requiring safety valves. Traditional metal-to-metal seated valves cannot achieve zero leakage due to surface limitations. The researchers modified the valves to use a soft PCTFE seal instead of a metal seal to eliminate leakage. They calculated force balances, seating stresses, lifting pressures, and leakage flows of the modified design. Experimental testing with liquid nitrogen showed the soft-seated valves achieved zero leakage at 90% of the set pressure, addressing safety issues with cryogenic applications.

GENERAL INFORMATION
FAST AVAILABLE ITEMS
Items which are available faster are marked by * in the catalogue. Though it does not indicate
any definate period of delivery, these items can be manufactured faster than the other items of
its range. For example, Pipe section PS18/1000 can be supplied faster than any other pipe
section of 450DN. This is because of following reasons :
- Semi finish goods or raw material for these items will be always available.
- Method of production of these items are set.
- Being fast moving items, these items may be available ex-stock with us.
REPAIRS
Though any damaged glass equipment can be repaired, mostly it is not economical to do so.
Generally, the repair which involves less than a third of its original work, is worth to carry out
repairing. Repair work is costly because :
a. It generally require greater skill than making a new one.
b. Since it involves high risk of total breakage, the risk of total loss of time spent on its
repairing goes along with.
c. The work involved in receiving a damaged equipment, identifying it throughout the
handling, cleaning it, estimating its repairing charges, re- estimating the repairing
charges in case damage extends etc are relatively expensive.
d. Each job require individual attention throughout the execution.
However, while sending an equipment for repairing, following care must be taken :
a. Inform the nature of breakage and get an estimate of repairing charges in advance to
avoid the loss of transportation expenses in case it is uneconomical to go for repairing.
b. Since repairing takes longer time to fit into production schedules and completion of
repairing is highly uncertain, it is generally suggested to arrange for a substitute
equipment to continue the work.
c. Equipment to be repaired should be clean. Since it can be cleaned better and at less cost
at owner's premises, it should be cleaned before sending it for transportation. This also
makes it safer to transport.
d. Pack with extra care, since cracks in glass have a tendency to extend with every jerk.
e. If possible, send broken pieces alongwith it.
f. Generally repairing work is accepted only for the equipment manufactured by us, and are
repaired at owner's risk only.
DIMENSIONS, WEIGHTS AND SPECIFICATIONS
In this catalogue, dimensions, weights and other specifications are taken more or less in
accordance with Corning. This is to keep the flexibility of maximum interchange ability.
However, some difference are unavoidable due to local manufacturing conditions. All the odd
dimensions are rounded off.
All the dimensions and weights are approximate. The specifications given in the catalogue are
intended to present a general description of the items. Since manufacturing of glass

INTRODUCTION
Tapered glass joints are predominantly used in industrial glass equipments. This design has a
high ratio of radial to axial force, which frequently leads to breakage while tightening the flange
joints.
A cylinder can withstand a much higher axial force than radial force plus glass has a very high
compressive strength. We at GOEL recognized these features and by our innovative design
practicesdevelopedXTRONG joints.TheXTRONG jointsaresodesignedthattheharmfulradial
stresses are dramatically reduced. For a given axial force the radial forces are 14 times lesser
thanthatintaperedjoints.
XTRONG joints are practically many times stronger than conventional tapered joints, As far as
tighteningofjointsareconcern,itistestedthataXTRONG jointsdoesnotbreakevenatatorque
of 20Nm, as against tapered joints, which starts breaking at 6-7 Nm torque. At times it may
happen that beacuse of over tightening, a metal backing flange breaks or the threads of nut-
boltsgivewaybutXTRONG glassjointremainsintact.
Most of the old glass installations in general contain equipments with tapered glass joints.
XTRONG joints are fully compatible with these tapered joints. i.e. an XTRONG equipment can
replace another tapered equipment and vice versa in any existing unit. This interchangeability
makesXTRONG designmoreadaptableingeneralconditionsandchangeovercostisnegligible.
XTRONG joints
XTRONG joints have been developed, to arrest the frequent breakage and leakage problems.
The XTRONG joints are so designed that the harmful radial stresses are dramatically reduced.
For a given axial force the radial forces are 14 times lesser than that in tapered joints.

Borosilicate glass represents unmatched standardized glass for construction of plant
and piping in the chemical, dyestuff, food pharmaceutical, petrochemical industries. Its
steadily growing use is due to many advantages over conventional materials.
- Outstanding corrosion resistence
- Smooth pore free surface
- Transparency
Borosilicate glass is chosen for its unique chemical and physical properties. Borosilicate
glass can be considered as being composed of Oxides, Silica (SIO ) Magnesia (MgO) and2
Lead oxide (PbO) are the principle modifiers/fluxes.
The chemical and physical properties of any glass depends on a varying degree on chemical
composition of glass.
CHEMICAL COMPOSITION
The composition of borosilicate glass used for chemical plants has following approximate
composion.
SiO2 - 80.6% B2 O2 - 12.5%
Na2O - 4.2% Al2 O3 - 2.2%
RESISTANCE TO CHEMICAL
Borosilicate glass is inert to almost all materials except Hydroflouric acid (HF) Phosphoric
acid(H3PO4) and hot strong caustic solutions. Of these. Hydroflouric acid has the most serious
effect, even when it is present in PPM (parts per million) in solutions. Where as phosphoric
acid and caustic solutions cause no problems when cold but at elevatrd temperature
corrosion occurs. In case of caustic solutions, upto 30% concentration can be handled safely
at ambient temperature.
Under actual operating conditions, the effect of turbulence, and traces of other chemicals
in the solution may increse or decrease the rate of attack. So it is not possible to give exact
figures for corrosion by caustic solutions.
THERMAL PROPERTIES
Linear coefficient of thermal expansion
0
The coefficient of thermal expansion of borosilicate glass over the temperature 0-300 C
-6 0
is 3.3 x 10 / C. This is very low when compared with other glasses and metals. That is
why, borosilicate glass is often called low expansion borosilicate glass.
Specific heat
0 0 0
Specific heat between 25 C and 300 C is average to be 0.233Kcal/Kg, C
Thermal Conductivity
0
Thermal conductivity is 1.0 Kcal/hr,m C. Over the permissible operating temperature range.
ANNEALING
Annealing of glass is the process where the glass is heated and kept for a defined period of
time to relive internal stresses. Careful cooling under controlled conditions is essential to
ensure that no stresses are reintroduced by chilling/cooling.
RESHAPEING
In the below given table, it shows characteristic temperature at a determined viscosity,
essential for glass reshape.
24 0
Lower cooling temperature 10 poise 515 C
13 0
Upper cooling temperature 10 poise 565 C
7 0
Softening point 10 poise 795 C
4 0
Reshapeing point 10 poise 120 C
MECHANICAL PROPERTIES
The lack of ductility of glass prevents the equalization of stresses at local irregularities or
flows and the breakage strength varies considerably about a mean value. This latter is found
2
to occur at a tensile strength of about 700kg/cm In order to allow for the spread of breaking
stress, a large factor of safety is applied when determining the wall thickness requirement to
allow operation up to values given in the table of working pressure.
- Catalytic intertness.
- No effect on taste and odour
- Physiological intertness.

TECHNICAL INFORMATION
OPTICAL PROPERTIES
Borosilicate glass show no appreciable absorption in the visible region of spectrum and
therefore appears clear and clour less.
In photo chemical processes, the transparency of ultra violet is of particular importance. It
follows from the transmittance of material in uv region that photo chemical reactions such
as Chlorination & Sulpho Chlorination can be performed in it.
PERMISSIBLE OPERATING CONDITIONS
Working Pressure For Glass Pipelines & Vessels
The permissible internal operation pressure depends upon the
nominal diameter of the glass components and on working
temperature.
In case of unit with various combination like vessels, filters,
heat exchangers, the over all permissible internal gauge pressure is
always governed by the component with the lowest permissible
operating gauge pressure all components are suitable for full vacuum
Bar is a measure of absolute pressure. The figure given for
maximum recommended working pressure represents pressure above
atmosperic.
Working Temperature
Borosilicate glass retains its mechanical strength and will deform only at temperature which
approach its strain point. The practical upper limit for operating temperature is much lower
and is controlled by the temperature differentials in the glass which depends on the relative
temperature of the contents of the equipment and the external surroundings. Provided
borosilicate glass is not subject to rapid change in temperature, creating undue thermalshock,
0
it can be operated safely at temperatures upto 250 C
It must be realised that in complete plants, composed not only of borosilicate glass, but also
include other materials such as PTFE. The recommended max. operating temperature is
0
200 C. Operating temperatures may have to be modified so as to compensate for the
effects of other factors such as pressure, thermal cycling, rapid heating & cooling etc.
The degree of thermal shock (usually defined as sudden chilling or heating) which it can
withstand depends on many factors such as stresses due to operating conditions, stresses
imposed in supporting the equipment, the wall thickness of the glass. It is therefore
0
undesirable to give sudden temperature changes. But up to 120 C can be accomodated.
As sub zero temperature, the tensile strength of borosilicate glass tends to increase and
0
equipment can be used safely at temperatures as low as -50 C for XTRONG and components.
COMPOSITE MATERIALS
The last two decades have seen the new or further developments of particularly corrosion
resistant plant construction materials. Typical examples of these are PTFE, tantalum,
titanium, graphite and of course, Borosilicate 3.3 Glass.
The combination of different corrosion resistant materials with the utilization of the specific
advantages of each permits both safe and economic construction.
Borosilicate glass/PTFE
Borosilicate Glass with PTFE is of particularly decisive importance for construction of glass
installation For example. in Seals, Bellows, Stirrers, Pumps, Heat Exchangers, Column Inserts
etc.
PTFE is used with Glass because of its excellent mechanical & thermal properties. They have
near universal fluid compatibility. Wear life when compared with others is very low.
Particularly PTFE is maintenance free and have cryogenic stability with non wetting property.
0 0
Service temperature of PTFE is considered as - 50 C to + 200 C
ELECTRICAL CHARASTERISTICS
Glass being a poor electrical conductor, surface, conductivity is insignificant and varies
0
with the quantity of water absorbed on glass surface. The specific conductivity is 10 ohm/cm
0
at temperature of 200 C.
The dielectric coefficient varies with current frequency.

EXTRA PROTECTION OF GLASS
COMPONENTS 'X-BONDING’
X BONDING provide an added advantage of protection of standard glass components. The
major advantage of X-Bonding systems is that if the glass is subject to accidental breakage, the
bonded wrapping provides additional protection against the risk of injury, release of corrosive
fluids or loss of expensive products.
X BONDING is a glass reinforced fibre coating which provide a higher level of protection on the
glass components. This does have a slightly adverse effect on the transparency of the glass,
makingittranslucent¬transparent.
PermissibleOperatingTemperature:
