Features and Benefits |
|
| |
Stronger, Resilient and Longer Lasting
: This system is highly resilient, tough and durable
with high tensile strength and high impact strength.
More over it is free from weakness caused by scale formation,
rusting, weathering and chemical action and hence lasts
for a life time. Minimum estimated life of PARAS Super
Flow ASTM system is 50 years, and hence the system is
a long term plumbing solution for building industry.

|
|
Excellent
corrosion and chemical resistance : |
|
| |
This system is immune to electrolytic
and galvanic corrosion and has excellent resistance
to great number of chemicals like strong mineral acids.
|
|
| |
|
|
|
Most suitable for carrying
drinking water : |
|
| |
Being non metallic this system is free
from corrosion and chemical action, hence absolutely
safe for carrying potable water.
|
|
| |
|
|
| |
No sediment deposition,
no reduction in bore size: |
|
| |
PVC is free from rusting, pitting or
scale formation. Hence there is no particle deposition
and the inner bore of the pipes remains undiminished
throughout the life of the system.
|
|
| |
|
|
| |
Optimum flow rates : |
|
| |
The interior walls of the pipes and
fittings have a mirror smooth finish. This ensures high
flow rates and low frictional losses.
|
|
| |
|
|
| |
Simple and leak proof
Joints : |
|
| |
Jointing can be done speedily with
the special solvent cement supplied by the company which
ensures 100% leak proof joints.
|
|
| |
|
|
| |
UV Stabilized : |
|
| |
This system is UV stabilized which
eliminates the adverse affect of sunlight and weather.
The system can therefore, be safely used for outdoor
installations.
|
|
| |
|
|
| |
Quality of Solvent Cement
: |
|
| |
Quality of solvent cement plays an
important role and influence the joint strength. Hence
it is recommended to use specially formulated heavy
duty solvent cement supplied by the company for trouble
free performance of the system.

Joining Instructions |
| |
|
| |
Cutting the pipe : Cut
the pipe square with hand saw with suitable
guide or by pipe cutter. Joint preparation
: Chamfer or deburr pipe or both, approximately
at 10°-15°. Remove burrs from inside
and outside diameters with a knife file
or abrasive paper.
|
| |
|
| |
Test dry fit of the
joint : Insert the pipe into the fitting
and check that the interference occur about
1/3rd to 2/3rd of the socket depth. Too
tight or too lose fitment may lead to leak,
hence should be avoided.
|
| |
|
| |
Cleaning : Remove
any dirt, moisture, or grease from pipe
end and fitting sockets with a clean dry
rag.
|
| |
|
| |
Roughening : Roughen
the contacting surfaces i.e. outsides of
the pipe and the inside of the socket using
sand paper or emery cloth.
|
| |
|
| |
Application of solvent
cement : Apply cement lightly but uniformly
to inside of socket and outside of pipe
and with a natural bristle nylon brush or
suitable applicator. Apply a second coat
of cement to the pipe end. Do not apply
excessive cement in bell socket. Apply cement
rapidly and be sure to completely cover
all jointing surface area of the pipe and
fittings.
|
| |
|
| |
Assembly of joint :Immediately
after applying the last coat of cement to
the pipe (within 20 second) forcefully bottom
the male end of the pipe in the socket,
giving pipe or fitting ¼ turn to
evenly distribute the cement. Remove excess
cement from the pipe at the end of fitting
socket. The joint must not be disturbed
immediately after cementing, so that joint
can properly cure. Allow cement to cure
before pressurizing the system.
Recommended curing time is 12 hours.
|
| |
|
| |
When the system is to
be concealed it should be pressure tested
before concealment. This system is not recommended
for geyser outlets and hot water supply.
