Branch Outlet Products

Union branch outlet

The union branch outlet is formed by integral hot forging, with the saddle base fitting the outer wall of the main pipe for welding, and the branch end comes with an MSS SP-83 standard high-pressure union, allowing quick unscrewing for maintenance, isolation of instruments and valves, without the need to cut the pipeline or dismantle welds. The body reinforcement follows MSS SP-97, the union seal and threads comply with ASME B16.11 and MSS SP-83, with domestic equivalents GB/T19326 and GB/T14383. Main pipe NPS2-NPS48, branch NPS1/8-NPS2, pressure ratings 3000LB and 6000LB, sealing available in two types: spherical hard seal and gasket soft seal. Materials cover carbon steel A105, LF2 low-temperature steel, 304/316L stainless steel, F11/F22 chrome-molybdenum alloy steel, 2205 duplex steel, and nickel-based alloys. Suitable for high-pressure instrument branch projects with dense instruments, high-frequency disassembly and assembly, prohibition of hot work, and requirements to reduce weld leakage points.
