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.
Although Type I PVC can be satisfactorily used for many applications at temperatures of up to 140Â° F, its strength and creep characteristics are altered. CPVC shall carry a maximum operating temperature of 200Â° F and has the same self-extinguishing and low conductivity features as PVC.hare This: The primary limitation of PVC material is the recommended environmental temperature limit of 140Â° F (60Â°C). This limit is not only a structural strength limitation but also a corrosion resistance limitation. Both can decrease rapidly as the temperature increases.
