CPVC Pipe

CPVC has similar, but generally better, chemical resistance and physical properties than PVC. Joining methods are by solvent cementing, threading (Schedule 80 only) or flanging. CPVC has been used successfully for process piping, for hot corrosive liquids, and in hot and cold water distribution. Pressure ratings given are for solvent cemented systems. When adding valves, flanges or other components, the system must be derated to the rating of the lowest component: threaded ratings are 50% of solvent-cement systems; flange fittings are 150 psi. See manufacturer`s recommendations for other fitting and component ratings.
