CPVC pipe 3 inch suits hot water mains in large buildings and some industrial process lines. Its size carries high flows to many outlets.
Because CPVC resists many chemicals, plants also use it for warm process water. However, check chemical compatibility with us first.
What is CPVC pipe 3 inch?
CPVC pipe is made from chlorinated polyvinyl chloride. The extra chlorine lets it handle higher temperatures than standard PVC, so it can carry hot water.
CPVC is joined with CPVC solvent cement, which differs from ordinary PVC cement. It also resists many chemicals, so it is used in some industrial lines.
