What is Socket Weld Union
Socket weld union dimensions is designed and manufactured according to MSS SP-83 standard, the weight is more heavier becuase it consists of three parts that a male end, a nut and famale end. The joint can be disassembled as a pipe fitting, and the things connected through the joint can be disassembled and replaced.
Socket weld pipe union is stronger and can hold the parts together more effectively because of the sockets. The joint can be disassembled as a pipe fitting, and the things connected through the joint can be disassembled and replaced.
The basic difference between couplings and unions is that couplings are used to connect pipes to bends. Union are used to connect and disassemble a part of the piping system (drain valve or control valve, etc.) for maintenance or replacement.
Specification for Socket Weld Union
MSS SP 83 socket weld union size range is from 1/8" to 3" and pressure rating is available in Class 3000 / 6000 lbs. Socket Weld Fittings are 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.

Carbon Steel for Socket Weld Elbow
ASTM A105 is the most commonly used carbon steel material grade that used to manufacture forge piping components such as flange and forged fittings of small diameter piping. This carbon steel material grade is used for ambient- and higher-temperature service in pressure systems.

Uses and Applications for Socket Weld Fittings
The high pressure ratings of socket weld fittings mean they are ideal for a wide range of industrial applications.
-SW pipe fittings can be used in pipelines to transport flammable, toxic or hazardous chemicals safely due to the lowered risk of leakage compared to other joining techniques.
-Creating a leak-free permanent join, SW pipe fittings also allow for excellent flow characteristics. When manufactured to ASME and ASTM standard specifications, these fittings are shown to have met requirements for performance, including tolerances, pressure and temperature ratings, dimensions, materials and markings.
-Socket weld pipe fittings are divided according to material type, such as alloy or carbon steel and stainless steel pipes. The different types of fitting lend themselves to different applications, whether couplings, reducers, reducing and regular socket weld tees, elbows, or flanges, with each available in different material types.
