CPVC (Chlorinated Polyvinyl Chloride) is a high-performance thermoplastic engineered for corrosive and hot-fluid piping systems. It resists a wide range of aggressive chemicals — including sulfuric acid, hydrochloric acid, sodium hypochlorite and ferric chloride — at service temperatures well above the limits of standard PVC.
Huiya supplies a complete CPVC piping range — pipe, fittings and valves (ball, butterfly, diaphragm and check) — available in both DIN metric and ANSI/ASTM Schedule 80 dimensions to suit project specifications worldwide. for chemical processing, water and wastewater treatment, electroplating and mineral processing applications. Our CPVC is produced from compound with a chlorine content above 60% (the common industry baseline is around 58%), giving more stable temperature and corrosion resistance, and every product is backed by a 12-month quality warranty.

CPVC extends PVC’s chemical resistance to higher temperatures. To see exactly which media it holds at your temperature, check our material-by-chemical resistance chart.
CPVC diaphragm valves bridge the gap between general-purpose UPVC and high-end PVDF: they hold up to hot corrosive media to about 90 °C — hot water, dilute-to-moderate acids, and oxidising bleaches — at a fraction of the cost of fluoropolymer. We supply them in true union, flanged, and pneumatic configurations for hydrometallurgy, metal finishing, and […]

Industrial CPVC Ball Valve (Manual) Industrial CPVC ball valves give you quarter-turn on/off control of hot corrosive and oxidising media to about 90 °C — hot water, dilute-to-moderate acids, and bleach — in a hand-operated valve built for process duty, not domestic plumbing. We make ours from virgin CPVC to Schedule 80 dimensions with a

CPVC Butterfly Valve (C-PVC) CPVC butterfly valves (C-PVC) give you compact, quarter-turn control of large-bore hot and corrosive lines — DN50 to DN500 — in wafer and lug bodies with a CPVC disc and an EPDM or FKM seat. They hold up to about 90 °C, the space-saving, economical choice for big-flow isolation and throttling
