What Is a CPVC Pipe?


CPVC is a chlorinated polyvinyl chloride thermoplastic pipe made out of CPVC compounds. CPVC pipes are approved for use in industrial and residential plumbing. They are corrosion resistant and durable.


  • Polyvinyl chloride was discovered in the 19th century. Manufacture of chlorinated PVC pipe began in Germany in 1931.


  • CPVC is a thermoplastic material, a plastic that turns into liquid when heated and turns glassy when frozen.


  • CPVC pipes are used for hot and cold potable water flow, sprinkler systems in homes and businesses and the transport of corrosive fluids in industry.


  • Industrial CPVC pipes range in size from 1/4 inch to 12 inches in diameter. CPVC for small-scale plumbing ranges in size from 1/4 inch to 2 inches in diameter.


  • CPVC pipe is easier to install than copper and iron pipes. CPVC pipes will also keep water hot longer than copper pipes because of better insulation. The pipes are not combustible which make them a better choice for sprinkler systems than metal pipes.
