Corzan® CPVC pipe and fittings are manufactured from CPVC compound manufactured by Lubrizol. Our piping material is the only CPVC for industrial systems that meets cell class 24448 for high impact and high heat distortion temperature pipe. Standard CPVC compounds have a 23447 cell classification.
Corzan piping is available in schedule 40 and schedule 80 as well as iron pipe sizes (IPS) through 24-in. diameter. Cell class 24448 piping material is available in sizes from ¼-in. to 8-in. from select manufacturers, and pipe sizes greater than 8-in. meet cell class 23447.
NSF International certifies corrosion-resistant Corzan pipe for use with potable water. It is available for use in both pressure bearing and drain applications at temperatures up to and including 200°F (93.3°C). Pressure ratings vary with schedule, pipe size, compound type and temperature.
Corzan CPVC meets a cell class never before achieved by any other CPVC compound manufacturer. This cell classification (as defined by ASTM D1784) means Corzan CPVC is proven to have the highest impact resistance and heat deflection temperature (HDT) of any CPVC compound.
Schedule 40 and 80 pipe meets or exceeds the requirements of ASTM F441. Associated fittings meet or exceed the requirements of ASTM F437 (scheduled 80 threaded) and ASTM F439 (schedule 80 socket).
A system design should be done in accordance with the manufacturer’s instructions. The design should also take into consideration specific factors, including: pressure and flow requirements, friction loss, operating temperatures, support spacing, anchoring, bracing and thrust blocking, joining methods, and thermal expansion and contraction.
