Stainless steel socket weld union is a socket joint design, It consists of three interconnected pieces. Union are used to connect and disassemble a part of the piping system (drain valve or control valve, etc.) for maintenance or replacement.
Socket weld union is stronger and can hold the parts together more effectively because of the sockets. It is a family of high pressure forging fittings that used only in conjunction with ANSI Pipe and are available in the same size range. Even though there are some similarities between the shapes of the two welds, but socket weld is still considered to be different from a fillet weld.
Stainless steel is a corrosion-resistant alloy of iron, chromium and, in some cases, nickel and other metals.Stainless steel Socket weld Union is used to permanently join pipes that are inserted into a recess in the fitting, flange or valve.
Stainless Steel Socket Weld Union Specification
Size Range | 1/8" – 3" / DN6 - DN80 |
Pressure Rating | Class 3000 |
Standard | MSS SP-83 |
Stainless Steel | ASTM A182 F304/304L/304H, 316/316L, 321, 310S, 317, 347, 904L，1.4404, 1.4437. |
Duplex Stainless Steel | ASTM A182 F51, F53, F44 |
Application | Oil and Gas /Pipeline/Power Industries/Chemical Industries |
Advantages for Socket Weld Fittings
The pipe is no need beveling for preparation of weld.
The welding position can adjust to flat welding.
Generally no need temporary tack welding for alignment. This is because the fitting principle helps to ensure that the alignment is correct.
The socket weld metal is not be able to penetrate the bore of the pipe.
It has found that socket welding is more economical than butt welding. Due to elimination of special machines and reducing precision assembly requirements.
