PVC that has undergone chlorination, making it more suitable for higher temperatures.

The pipes are produced in copper tube size (CTS) from 15 mm (½”) to 50 mm (2”) with two different standard dimensional ratios – SDR 11 and SDR 13.5 (Class 1 & Class 2 respectively as per IS:15778) . The fittings are produced as per SDR 11. The pipes and fittings in SDR 11 class is complies to ASTM IS:15778 & IS:17546 standard. All Darsh Industries CPVC SDR 11 and SDR 13.5 pipes are made from identical CPVC compound material having same physical properties. The CPVC fittings are manufactured from compound material which meets all the requirement as per ASTM standard. Apart from having the same physical properties, SDR 11 and SDR 13.5 which are having different wall thickness and therefore, at any given temperature, they have different pressure ratings.

Darsh Industries also manufacture CPVC PRO pipes in iron pipe size (IPS), available sizes are 65 mm (2½”) to 300 mm (12”) in SCH 40 and SCH 80 which meets the requirements of ASTM F 441. The pressure ratings varies with schedule pipe size and temperature. CPVC pipes of Copper Tube Size (CTS) dimensions can also be connected to CPVC (IPS) dimensions by using IPS x CTS fittings.

Material:
Similar to PVC but without added plasticizers, making them more rigid.

Properties:

• Higher temperature resistance (up to 200°F/93°C).
• Excellent corrosion and chemical resistance.
• Non-reactive to chemicals, acids, and water minerals, making it ideal for hot water applications.
• Strong yet lightweight, easy to install.

Applications:

• Hot and cold water plumbing.
• Industrial fluid handling systems.
• Fire sprinkler systems.
