Reducing couplings create a smooth, transparent inline transition to connect two different pipe diameters for straight-line pipe size reduction. The tapered inner profile cuts down fluid turbulence and pressure drop during diameter transition. Its high transparency enables real-time visual inspection of flow velocity and sediment buildup inside the reducing section.
Smooth Tapered Transition: Internal taper ensures gradual flow compression, minimizing turbulence and pressure loss.
Visual Acceleration Check: Allows clear observation of fluid velocity shifts and clarity changes through the reduction area.
Space-Saving Reducer: Compact inline socket design joins different pipe sizes without adding bulk to the piping network.
Reliable Solvent Bonding: Precision socket diameters ensure strong, leak-free bonded joints with standard clear PVC pipes.
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.
