UPVC SOCKET FLANGE

UPVC socket flanges provide a plastic welding flange solution for joining UPVC pipe sections to flanged valves, pumps, and equipment, manufactured by injection molding to consistent dimensional standards across the full size range.

Key specifications:
• Manufactured to DIN and GB standards, with flange face compatibility across ANSI 150#, DIN PN10, JIS 10K, and ISO standards, supporting installation into pipeline systems built to different international specifications.
• Socket connection to the pipe, joined by solvent cement or fusion, forms a strong, leak-resistant bond between the flange and the UPVC pipe run.
• Water absorption below 0.01% and contraction percentage below 0.4% reflect the material stability required for dimensionally consistent, long-term flange performance.
• Tensile strength of 41-50 MPa provides the mechanical strength needed for bolted flange connections under standard pressure service.
• Flat face (FF) sealing surface rated PN10 matches standard gasket and bolting practice used across plastic and metal flanged systems.
• Available across DN15 to DN300, covering the great majority of piping sizes used in water treatment and general chemical process applications.

Injection-molded manufacturing produces consistent flange geometry and bolt-hole spacing, helping ensure a reliable seal when the flange is bolted to a mating flange on a valve, pump, or another pipe section.

Typical applications include water treatment plant piping, general chemical process lines, and any UPVC piping system requiring a bolted flange connection to interface with valves, pumps, or equipment built to standard flange dimensions.
