ASTM A182 Standard?
This specification covers forged low alloy and stainless steel piping components for use in pressure systems. Included are flanges, fittings, valves, and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications that are referenced in Section 2.
A Socket Weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. In contrast to buttweld fittings, Socket Weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller.

Socket Weld Cross
| A cross is a pipe fitting with four interfaces. In a socket weld cross, the interfaces can be four sockets or one socket and three spigots. A cross is mainly used to divide a main pipe into three branch pipes or to converge three branch pipes into one main pipe. |
Socket Weld Coupling
| The socket coupling is a kind of pipe fitting, whose main function is to connect two pipes of the same diameter, which can extend the pipe or facilitate disassembly when the pipe needs to be repaired or replaced. |
Socket Weld Cap
| A cap is a pipe fitting used to seal the end of a pipe. One end of the cap is a closed arc or plane, and the other end is a socket or spigot. The main function of the pipe cap is to prevent the medium in the pipe from leaking, and it can also protect the end of the pipe from erosion by the external environment. |
Socket Weld Union
| The main function of the union is to facilitate the installation, disassembly and maintenance of the piping system. |
Socket Weld Fittings Application and Usage
ASTM A182 socket weld Fittings are used wherever liquids, gases, chemicals and other fluids are created, processed, transported, or used. Range of industries is very wide, as shown below:
Energy related
Oil and gas industries, including upstream (exploration and production), midstream (transportation by ships, pipeline, rail, trucks; storage and wholesale) and downstream (refining into fuels or chemicals; marketing and distribution). Power plants using fossil or nuclear fuels. Geothermal energy for harnessing heat from the earth.
Chemical Industry
In the production process of chemical raw materials, the piping system needs to handle a variety of highly corrosive media. ASTM A182 socket fittings can resist the erosion of these corrosive media if they are made of corrosion-resistant alloy or stainless steel.
