Irrigation & water supply

Rigid PVC (R-PVC)

IS: 4985

Full specification
What is the expected lifespan of these pipes?

When installed correctly underground, Peregrine Rigid PVC pipes have a service life exceeding 50 years due to their resistance to corrosion and biological attack.

Rigid PVC (R-PVC) specification
Are these pipes safe for drinking water?

Yes, our R-PVC pipes are non-toxic, lead-free, and do not impart any taste or odor to the water, making them safe for potable water supply.

Rigid PVC (R-PVC) specification
How are the joints sealed?

They can be joined using Solvent Cement for smaller diameters or Elastomeric Sealing Rings (Rubber Rings) for larger diameters to ensure leak-proof connections.

uPVC Plumbing Pipes

ASTM D1785 · IS: 12235

Full specification
Can I use uPVC pipes for hot water?

No, uPVC pipes are suitable for cold water distribution up to 60°C. For hot water applications, we recommend our cPVC range.

uPVC Plumbing Pipes specification
Does it require threading?

No, uPVC plumbing pipes utilize solvent cement joining (cold welding), which is faster, easier, and more leak-proof than threaded GI pipes.

uPVC Plumbing Pipes specification
Is it UV resistant for outdoor use?

Yes, our uPVC pipes are UV stabilized, making them suitable for outdoor installations without degrading under sunlight.

Hot & cold plumbing

Hot & Cold cPVC Pipes

IS: 15778 · ASTM D2846

Full specification
What is the maximum temperature cPVC can handle?

Peregrine cPVC pipes can withstand temperatures up to 93°C (200°F), making them ideal for geysers and solar water heaters.

Hot & Cold cPVC Pipes specification
Can I join cPVC with standard PVC glue?

No, you must use solvent cement specifically formulated for cPVC to ensure a strong chemical bond capable of withstanding high temperatures.

Hot & Cold cPVC Pipes specification
Is cPVC safe for drinking water?

Absolutely. cPVC is approved worldwide for potable water systems and does not support bacterial growth.

Drainage · soil, waste & rainwater

SWR (Selfit) Plumbing Pipes

IS: 13592

Full specification
What is the difference between Type A and Type B?

Type A is for rainwater and ventilation (thinner wall). Type B is for soil and waste discharge (thicker wall, stronger).

SWR (Selfit) Plumbing Pipes specification
How do I maintain these pipes?

SWR pipes are maintenance-free. Their smooth inner surface prevents scaling and choking, requiring no painting or coating.

SWR (Selfit) Plumbing Pipes specification

Drainage · soil, waste & rainwater

SWR (Ringfit) Plumbing Pipes

IS: 13592

Full specification
Why choose Ringfit over Selfit?

Ringfit pipes have a rubber seal that absorbs thermal expansion and contraction, making them ideal for tall buildings where temperature changes can cause pipes to move.

SWR (Ringfit) Plumbing Pipes specification
Does it leak over time?

The EPDM rubber ring ensures a permanent, leak-proof seal that does not degrade easily, provided it is installed correctly.

SWR (Ringfit) Plumbing Pipes specification

Borewell & tube well

BoreWell Casing

IS: 12818

Full specification
How deep can these pipes be installed?

CM (Casing Medium) pipes are designed for depths up to 250 meters, while CS (Casing Shallow) are for up to 80 meters.

BoreWell Casing specification
Will they corrode like steel pipes?

No, uPVC casing pipes are completely immune to corrosion from soil acidity or alkalinity, ensuring a much longer lifespan for your borewell.

BoreWell Casing specification
What thread type is used?

We use high-precision Trapezoidal threads that ensure strong joints capable of bearing the vertical load of the pipe column.
