Designed for in-line pipe size reduction across straight pipeline runs, the Industrial UPVC Reducing Coupling provides a smooth, gradual transition between two different pipe diameters. It preserves fluid velocity and minimizes system pressure drops in complex chemical processing and water treatment loops.
Technical & Design Advantages:
Concentric Tapered Bore: Smooth internal slope prevents abrupt flow disruption, cavitation, and fluid turbulence during diameter transitions.
High Burst Pressure Rating: Engineered with a heavy wall thickness matching or exceeding standard industrial pipe pressure ratings.
Chemical & Abrasion Protection: Highly resistant to aggressive chemicals, slurry friction, and scaling for extended operational life.
Standardized Socket Tolerances: Ensures clean insertion and deep solvent bonding with matching pipe sizes.
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. With over 30 years of industrial expertise, our 40‑acre factory boasts a building area of 50,000 m². As an original manufacturer for plastic pipes, fittings and valves, we serve domestic markets and export our products to more than 100 countries around the globe.
