As Per IS : 4984 - 1995
& IS 14333 - 1996 |
|
| |
|
|
|
MATERIALS : |
|
| |
It is made of either of three grades
of High Density poly ethylene polymers i.e. PE-63, PE-80,
or PE-100
|
|
| |
|
|
| |
PRODUCT RANGE : |
|
| |
These HDPE pipes are available in size
20m to 315mm in pressure rating of PN-2.5, PN-4.0, PN-6.0,
PN-8.0, PN-10.0, PN-12.5 & PN-16.0 in all three
grades PE-63, PE-80 and PE-100 respectively.

APPLICATIONS : |
|
| |
Effluent and Waste Water Disposal
:
Effluents of varied chemical compositions can be effectively
disposed of using PARAS HDPE Pipes, with the aid of
the latest know-how on piping engineering, pipelines
for waste collection and disposal in chemical industry.
Longevity of PARAS pipes under such application would
rate the best amongst the conventional pipe even under
critical service conditions.
|
|
| |
|
|
|
Domestic Gas Distributions
: |
|
| |
Earlier engineers always carried a
psychological fear in using HDPE Pipes rather plastic
pipe for conveyance of inflammable gases. However experiments
and extensive trials proved these fears totally wrong
and have established excellence of performance of HDPE
Pipes for conveyance of all type of combustible gases.
Experiments have also proved that the permeable losses
are insignificant in regard to safety and environmental
impact.
|
|
| |
|
|
| |
Submarine Pipelines : |
|
| |
One of the most important applications
where all salient features of PARAS pipes prominently
figure out is for underwater pipelines. Paras Pipes
have been successfully laid for under water river crossing,
creek crossing, marine out-falls and for brine intake
lines in the open sea. Hazardous chemical effluents
and radio active wastes are being harmlessly disposed
into deep sea through PARAS pipes with substantial cost
savings. Schemes which would have been dropped due to
economical un-viability have been made feasible with
PARAS pipes.

Benefits
of HDPE Pipes |
|
| |
|
|
No joints means
no leaks. |
|
|
HDPE pipe actually gains strength in lower
temperatures and will expand at higher temperatures
to avoid breaking.
|
|
|
HDPE pipe is designed to bend to a radius
of 25 times its diameter. This means fewer
90 degree bends overall, less chance for
water hammer, a reduction in leaks and easier
installation ideal for new construction.
|
|
 |
|
|
| |
|
|
HEPE pipes strength and flexibility
allows the pipe to absorb vibrations and stress
caused by soil movements.
|
|
|
With its ability to be compressed
or deformed without permanent damage, pipe has
even withstood the destructive forces of earthquakes.
|
|
|
Performs well in rocky conditions.
|
|
|
HDPE pipe can be buried at a shallow depth.
|
|
|
Here are no joints to pull apart.
A distinct advantage, where ledge rock prohibits
excavation and very little cover is available.
|
|
|
Weathrability
|
|
|
HDPE pipe can withstand long
exposure to inclement weather conditions. Excessive
sunlight and ultraviolet rays making it an excellent
pipe for bridge crossing.
|
|
|
Withstands full vacuum, HDPE
pipe will not collapse, even under a full vacuum,
when the correct size is used for a required application.
This allows for perfect utilization as intake
piping at pumps stations.
