INTRODUCTION
TM ASTRAL WIRE GUARD conduit pipes and fittings have
good impact strength, superior light proofness and
chemical resistance. It has high heat deflection
temperature and ductile behavior even at low
temperatures.TM ASTRAL WIRE GUARD conduit is the lightest in weight
compared to other materials and usually lower in cost then TM other terms of conduit. ASTRAL WIRE GUARD conduit is
available in three different wall thicknesses with the thin-
wall variety only suitable for embedded use in concrete
and heavier grades suitable for direct burial and exposed
work.TM ASTRAL WIRE GUARD conduit pipes and fittings resists
moisture and many corrosive substances. Joints to fittings
are made with slip-on solvent welded connections, which
set up rapidly after assembly and attain full strength in
about few hours.

Fire is one of the major hazards to life and property, and
electrical installations are perhaps one primary source of
generation and propagation of fire. Protection of cables
and raceways against fire is therefor an important and
primary consideration in the design and industry
standards.

VERSATILE AND ELEGANT
ENVIRONMENTAL IMPACT
TMASTRAL WIRE GUARD have high
mechanical strength that is attested by
tests conduced as specified in IS 9537: 3.
Hence they can be used both in open /
surface and concealed installation.
TM ASTRAL WIRE GUARD requires no
maintenance due to its excellent
weather protected properties.
T M ASTRAL WIRE GUARD electrical
conduit pipes last for a lifetime.
The physical properties of PVC allow
designers a high degree of freedom
while designing. Superior finished
pipes and fittings add a touch of
beauty to the buildings .
PVC has a lower feedstock energy
especially compared to other polymers
and common building materials. It is
the least energy intensive of all
thermoplastics. In life cycle analysis
and independent studies, PVC's
environmental impact has been found
most favorable, so the more usage of
PVC will greatly help to keep our global
natural resources intake for longer
period of time. It is not polluting air,
water or land during manufacturing or
service life and can be recycled after
prolonged service life.

TMASTRAL WIRE GUARD is non-corrosive
by nature and are not attacked by
corrosive, salty atmosphere & excessive
humidity. They are immune to chemical
and galvanic corrosion. Hence they are
ideal electrical conduits.
TMASTRAL WIRE GUARD do not support
combustion and when the source of
ignition is removed they are self
extinguishing.
TM ASTRAL WIRE GUARD is non-conductor TM of electricity. ASTRAL WIRE GUARD
conduit prevents electrical shocks.
Hence they are most suitable for
electrical conduits.
TMASTRAL WIRE GUARD have low specific
gravity, which implies that it is much
lighter than the pipes made from more ®traditional materials. ASTRAL Pipes are
therefore easier to handle. This result in
reduced transportation & installation
costs.
TMASTRAL WIRE GUARD have smooth
interior walls which helps in reducing the
friction thus helping in easy wiring.
TM ASTRAL WIRE GUARD can be shaped
and joined without difficulty.TMASTRAL WIRE GUARD Pipes are joined
by solvent cement, which is simpler,
cheaper & easier.

All conduit pipe and fittings expand and contract with
changes in temperature. All materials expansion and
contraction rates are represented by coefficients of thermal
expansion. A general rule of thumb is that for every 100°F
temperature change in a 100 ft. run of PVC conduit; the
conduit will undergo 3.6" of expansion or contraction.
EXPANSION AND CONTRACTION
USE OF EXPANSION JOINTS
In installations where the expected temperature variation
exceeds 25°F expansion joints must be used. An expansion
joint consists of two tubes, one telescoping inside another.
When installing expansion joints alignment of the piston and
barrel is important. Straps should be placed approximately
one foot on either side of the joint to ensure that any
movement is directed squarely into the joint.
LOCATION OF EXPANSION JOINTS
ONE EXPANSION JOINT
TWO EXPANSION JOINTS
Proper functioning of an expansion joint depends on three procedures :• The correct placement of the expansion joint.• The proper installation of rigid PVC conduit and the
expansion joint.• The proper placement and fastening of support straps.
If only one expansion joint is needed between two boxes, the barrel of the joint should be rigidly fastened close to the first box. Rigid PVC conduit should then be loosely supported with straps, allowing the conduit to move freely as it expands and contracts.
If two expansion joints are needed, the joints should be firmly fastened back to back at the center of the run. Rigid PVC conduit should be loosely supported with straps, allowing the conduit to move freely as it expands and contracts.
TWO EXPANSION JOINTS (ALTERNATIVE)
THREE OR MORE EXPANSION JOINTS
Alternatively, the center of the run and the two expansion joints (located at the boxes) should be rigidly fastened. All other support straps should be loosely fastened.
If more than two joints are needed in a very long run, they should be put in a series, one after the other. Each barrel must be rigidly fastened while conduit is loosely supported with straps allowing the conduit to move freely as it expands and contracts. When installed in a series, each section acts independently of the other.
When expansion joints are required the following steps
should be followed :
Use the following formula to calculate the total expected
expansion in the run.
Total Expansion =
The expansion joints should then be installed at even
intervals throughout the run.Number of Joints = Total expansion
4
The expansion joint must be installed to allow both
expansion and contraction of the conduit run. Because
installation temperatures may vary, the piston setting must
be determined. The correct piston opening is determined
using the following formula :Piston (in) =
max temperature (°F) - installing temperature (°F) x 4 Temperature change (°F)

stored at the job site on level ground in the unit package
(skids) provided by the supplier. Caution must be
exercised to avoid compression, damage or
deformation. When unit packages are stacked, care must
be used to ensure that the weight of the upper unit dose
not cause deformation to pipe in the lower units.
ASTRAL WIRE GUARD™ pipe must not be stored in tightly
enclosed areas subject to elevated temperatures. or
close to heat producing sources such as boilers, heaters,
steam lines, engine exhaust etc. Exposure to excessive
temperatures will result in distortion and deformation of
pipe.

Stack pipe lengths:
- either on a flat base or on level ground.
Ideally, stacks should contain one diameter pipe size
only. Where this is not possible, stack largest diameter
pipes at base of stack. Small pipes may be nested inside
larger pipes.
Store all materials in well ventilated, shady conditions.
If stored in the open for long periods or exposed to
strong sunlight, cover the stack with opaque sheeting.
Store fittings under cover. Do not remove from cartons
or packaging until required.
Store solvent cement and cleaning fluid in a cool place
out of direct sunlight and away from any heat source.

4. JOIN PIPE AND FITTINGS :
Cut pipe square. As joints are sealed at the
base of the fitting socket. An angled cut may result in joint
failure.
Remove all burr from inside
and outside of pipe with a knife-edge file, or deburring
tool. Chamfer (bevel) the end of the pipe 10° -15°
Remove surface dirt, grease, or moisture with a
clean dry cloth.
Apply a full even layer of cement to the outside
of a pipe and medium layer of cement to the inside of a
fitting.
Assemble pipe and fitting
socket till it contacts socket bottom. Hold pipe and fitting
together until the pipe does not back out. Remove
excessive cement from the exterior. A properly made joint
will show a continuous bead of cement around the
perimeter.

DO'S & DON'TS
DO'S
•
•
DON'TS
•
•
Always insist to use ASTRAL uPVC solvent cement for
making joints.
Cut the pipe straight, as improper cut may lead to
joint failure.
Do not insert the pipe into socket of fitting without
chamfering. This can disturbing while wire pulling.
Do not install pipeline without properly placed pipe
clips. This is required to ensure efficient working of
the system.

ON-SITE STORAGE
•
Take all reasonable care when handling
ASTRAL WIRE GUARD™ pipes particularly in very cold
conditions when the impact strength of the material is
reduced.
Do not throw or drop pipes, or drag them along hard
surfaces.
In case of mechanical handling, use protective slings
and padded supports. Metal chains and hooks should
not make direct contact with the pipe.
ASTRAL WIRE GUARD™ Conduit pipe and fittings may
be stored indoors or outside. If stored outside, pipe and
fittings should be protected from direct exposure to
sunlight and pipe should be properly supported in
storage to prevent sagging or bending. Pipe should be
