The CPVC Pipe Socket (Coupling) is engineered to join two straight runs of CPVC pipe with absolute joint integrity in high-temperature and high-pressure piping systems. Designed to create a monolithic, permanent bond using specialized CPVC solvent cements, this socket matches the pressure and temperature ratings of schedule-rated CPVC pipe. Its heavy-walled construction provides exceptional hoop strength, preventing joint expansion or micro-leakage under continuous hot fluid flow and pressure fluctuations. Featuring a precision-molded internal stop ring, it ensures exact pipe insertion depth and axial alignment during field assembly, streamlining installation while maximizing longitudinal pull-out resistance across critical process loops.
Technical & Design Advantages:
Deep-Socket Fusion Zone: Extended socket depth provides an expanded bonding surface area for maximum solvent weld strength under longitudinal pull-out forces.
Elevated Thermal & Mechanical Rating: Maintains high tensile modulus and pressure containment capabilities at continuous operating temperatures up to 93°C (200°F).
High Purity & Lead-Free Compound: Formulated without heavy-metal stabilizers, ensuring chemical purity and preventing fluid contamination in ultrapure chemical applications.
Seamless Center Stop Alignment: Molded internal center stop ensures balanced pipe seating and equal joint distribution during solvent cementing.
Zhejiang Feiya Plastic Co., Ltd. is located in Zhejiang Province, adjacent to Yiwu — the world‑renowned capital of small commodities. It enjoys convenient transport links to coastal cities including Shanghai, Hangzhou, Ningbo and Taizhou, backed by well‑developed logistics networks.
Our journey started in 1992 as Jiangshan Sanjin Machinery & Hardware Factory. We strategically turned to PVC piping production in 2001 and registered our proprietary FEIYA brand in 2002.
