Facilitating direct, straight line reduction between two different pipe sizes, our UPVC reducing couplings provide a smooth, efficient transition with minimal hydraulic resistance. The tapered interior profile minimizes turbulence and prevents fluid stagnation at the diameter change point. Precision-molded in our production facility with rigorous dimensional controls, these couplings are essential for maintaining balanced flow dynamics in water distribution and irrigation systems.
Smooth Gradient Transition: Gradual internal taper minimizes pressure drops and prevents particle settling at pipe size reductions.
Pressure-Resistant Engineering: Thick-walled construction is hydrostatically tested in-house for dependable performance under varying system loads.
Non-Toxic Composition: Certified lead-free and non-toxic, ideal for safe and durable potable water supply networks.
Rapid Solvent Welding: Factory-verified socket tolerances ensure quick alignment and leak-proof bonded joints on site.
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.
