This article presents PVC pipe fittings made from Chlorinated Polyvinyl Chloride (CPVC), a white, odorless, non-toxic engineering plastic. Key Applications: Pipes: Primarily for transporting hot water (up to 100°C) and corrosive chemicals, offering advantages of light weight and inherent thermal insulation. Industrial Uses: Suitable for factory hot sewage, electroplating solutions, and chemical reagent feed pipes. Injection Parts: Used in water supply lines, electrical components like wire channels, and cable insulation. Core Properties: High-Temperature Resistance: Withstands temperatures 30-40°C higher than standard PVC. Excellent Corrosion Resistance: Tolerates strong acids, strong alkalis, salts, and oxidizers. The increased chlorine content enhances heat deformation resistance. Storage & Shipping: Must be stored in a dry, ventilated warehouse, protected from sunlight and moisture. Transport requires covered vehicles to ensure protection from the
