CPVC and PVC pipes are made out of very strong and versatile materials. It is hard to believe that they are not completely resistant to UV rays. Chlorinated Polyvinyl Chloride (CPVC) is made when Polyvinyl Chloride (PVC) is treated with chlorinated water. They are available for engineering and industrial piping projects because CPVC can withstand a greater array of high temperatures.
Uses of CPVC. CPVC has similar uses as PVC. However, because of the chlorinating process, CPVC is able to withstand higher pressures and temperatures. CPVC has an upper temperature tolerance of 180 degrees, so it can be used for hot water pipes.VC. PVC stands for polyvinyl chloride. This type of pipe is less expensive than other types, resists cracking and isn't affected by acids. It is manufactured in white, gray and clear, and can be rigid or flexible.
