Stainless Steel Pipe Fittings
Stainless steel pipe fittings are the indispensable components for a piping system, they are widely used for chemical, water treatment, oil refinery, ship building, paper making industries etc. Kaysuns is a manufacturer for stainless steel and duplex steel pipe fittings, including stainless steel butt-weld fittings and forged fittings. We provide stainless steel elbow, tee, concentric reducer, eccentric reducer, caps, return bend, stub end, cross, and also custom fabrication as per designs that will fit the unique project.
Stainless Steel Buttweld Fittings
Stainless steel butt-weld fittings is our key product. Our factory is an ISO 9001 approved manufacturer in Zhejiang China. We provide full range of such elbows, tees, reducers, stub ends, caps, bends in materials stainless steel, duplex steel and super duplex steel, nickle-based alloy, titanium alloy, copper alloy etc to standard ASME B16.9, MSS-SP43, EN 10253-4/-3, ISO 05251, JIS, GOST and customized fabricated available.
Stainless Steel Forged Fittings
Stainless steel forged fittings are mainly the size under 6” as its connected end is socket-weld and threaded. We supply both socket-weld fittings and threaded fittings (NPT and BSPT) to ASME B16.11, BS 3799 etc.
For small order of stainless steel forged pipe fittings, we are ability to supply it from the stock with immediate shipment, including stainless steel F304, 316L and duplex 2205 etc.
