High-Temperature CPVC Hot & Cold Water Systems
Three Golden Arrows chlorinated polyvinyl chloride (CPVC) piping systems, manufactured by Bhardwaj Enterprises, represent the gold standard in premium hot and cold water transport. By post-chlorinating base PVC resin, the heat distortion temperature is elevated from 60°C to well over 93°C (200°F), enabling safe, continuous carriage of pressurized boiling water without softening or blistering.
Manufactured in the confirmed 20 mm to 110 mm (up to 4") diameter range in both SDR 11 (Class 1) and SDR 13.5 (Class 2), Three Golden Arrows CPVC pipes are fully compliant with ASTM D2846 and IS 15778 specifications.
Thermal Endurance to 93°C
Capable of withstanding continuous hot water circulation from solar geysers, boilers, and heat pumps under high operating pressures.
Low Thermal Conductivity
CPVC has exceptional insulating properties compared to copper and GI pipes, minimizing surface condensation and standby heat losses.
Fire Retardant & Non-Toxic
Limiting Oxygen Index (LOI) of 60 means CPVC will not support combustion in atmospheric conditions. Self-extinguishing with low smoke toxicity.
Chemical Fusion Weld
Joined via specialized one-step or two-step CPVC solvent cement that fuses polymer chains, creating joints stronger than the pipe itself.
