Socket Weld Flanges（SW Flanges) have a shoulder in which a pipe is inserted; it is a guide to set the depth at which the pipe is welded to the flange.
It is fabricated by inserting the pipe end into the flange until it bottoms out against the shoulder. Then the pipe is secured by one fillet weld located on the exterior of the flange hub.
Socket welding flange designed for high-pressure small diameters piping system(≤ 4 inches, ≤ 10cm), it is a common choice for limited space components. But not suitable for highly erosive or corrosive systems.
Socket welding flange Advantages: Corrosion resistance, cryogenic strength, abrasion and erosion resistance, surface finish, magnetic properties, ductility, high-temperature resistance, stability of in-service properties, suitability for planned manufacturing techniques
Application field： Oil and Gas, Chemical Industry, Plumbing, Heating, Water Supply Systems, Power Plant, Paper & Pulp Industry, Food Processing Industry, Structural Pipe, Fabrication Industry and General Purpose Applications etc.
