The UPVC Extended 90° Elbow for Mining is a heavy-wall directional fitting designed to execute sharp 90° pipeline turns in high-stress mining environments. Engineered with extended sockets and reinforced bend radii, this elbow absorbs line movement, vibration from slurry pumps, and severe hydraulic shocks while maintaining leak-proof system integrity.
Technical & Design Advantages:
Extended Socket Design: Provides extra contact area for solvent welding, guaranteeing structural stability under ground movement and thermal expansion/contraction.
Reinforced Wear Zone: Extra material thickness at the outer curvature prevents premature wall wear caused by abrasive solid particle impact during high-velocity slurry transport.
Hydrodynamic Flow Channel: Swept internal radius smooths out fluid flow transitions, reducing pressure drops and minimizing water-hammer shockwaves.
Non-Corrosive Material Composition: Completely immune to acid mine drainage, chemical reagents, and electrochemical corrosion, eliminating oxidation and maintenance overhead.
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.
