SIFFO Chlorinated Polyvinyl Chloride (CPVC) Chemical Pipes are engineered for aggressive industrial applications requiring superior thermal and chemical resistance. Manufactured under strict ASTM F441 guidelines, these pipes excel in high-temperature fluid transport (up to 93°C) while maintaining structural integrity. Ideal for corrosive environments in chemical plants, semiconductor facilities, and hot water systems.

Key Features
·High-Temperature Endurance – Withstands continuous operation at 82-93°C (180-200°F), outperforming standard PVC.
·Enhanced Chemical Resistance – Resists acids, alkalis, salts, and hydrocarbons (compatibility charts available).
·Flame Retardant – Self-extinguishing (UL94 V-0 rated) for safer use in industrial zones.
·Smooth Bore Design – Minimizes pressure drop and prevents scaling/biological buildup.
·Long Service Life – 50+ years with negligible maintenance under ASTM F441 stress ratings.
Application Fields
·Chemical Processing – Concentrated acid/alkali transfer (e.g., HCl, NaOH ≤40%).
·Hot Water Systems – Factory boilers, heat recovery loops (≤93°C).
·Semiconductor Plants – Ultra-pure water and chemical distribution.
·Oil & Gas – Non-flammable hydraulic lines and brine transport.
