Chlorinated Poly Vinyl Chloride - CPVC - is a thermoplastic pipe and fitting material made with CPVC compounds meeting the requirements of ASTM Class 23447 as defined in ASTM Specification D1784.
CPVC applications are for potable water distribution, corrosive fluid handling in industry, and fire suppression systems.
