PVC vs CPVC

PVC vs CPVC

PVC stands for Polyvinyl Chloride and it is usually used for water, gas, and drainage systems that do not exceed 140° F (60° C). It is not usable for hot water systems.

CPVC stands for Chlorinated Polyvinyl Chloride, and is more rigid and more corrosion resistant than PVC because of the added chlorination. The major difference is that is can withstand higher temperature of up too 180 °F (82° C), and this is why it is used for hot water systems.

CPVC can be distinguished from PVC because of its yellow coloration as seen in the pictures below.

NOTE: Sizing for PVC and CPVC is described below. Related documents are available as well at the bottom of this blog posting.

  • PVC is covered by ASTM D2665
