Environmental stress cracking (ESC) is one of the leading causes of plastic pipe failure. It occurs when the piping material is simultaneously subjected to mechanical stress and certain types of chemicals.
Corzan® chlorinated polyvinyl chloride (CPVC) offers the peace of mind that comes with a piping system that provides superior resistance to corrosive chemicals at high temperatures and pressures. Corzan CPVC can be used for pressurized service up to 200°F and offers a higher pressure rating over most of its useful temperature range than most of the other thermoplastic materials used for industrial piping. as illustrated in the chart below.
