Designed for in-line pipe size reduction across straight elevated-temperature pipeline runs, the CPVC Reducing Coupling provides a smooth, gradual transition between two different pipe diameters. It preserves fluid velocity and minimizes system pressure drops across hot chemical processing loops and industrial boiler feed lines. The concentric internal taper prevents abrupt flow disruption and fluid turbulence, protecting connected piping from cavitation and localized stress points. Manufactured with a heavy wall profile matching or exceeding schedule-rated pipe standards, it offers exceptional resistance to internal pressure spikes, thermal shock, and aggressive chemical degradation.
Technical & Design Advantages:
Concentric Tapered Bore: Smooth internal slope prevents abrupt flow disruption, cavitation, and fluid turbulence during diameter transitions.
High Thermal & Pressure Rating: Engineered with a heavy wall thickness designed to maintain rated pressure containment at elevated operating temperatures.
Chemical & Abrasion Protection: Highly resistant to aggressive hot chemicals, slurry friction, and mineral 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.
