Metal Socket Weld Union
A Metal Socket Weld Union is a three-piece pipe fitting designed to join two pipes using a socket weld connection, while allowing easy disassembly without cutting the pipe. It consists of two end pieces and a central nut, which ensures a secure, leak-proof joint. Unlike couplings, socket weld unions can be easily removed for maintenance, inspection, or replacement of pipe sections. Manufactured from carbon steel, stainless steel, alloy steel, and duplex steel, these fittings are built for high-pressure and high-temperature applications in industries such as oil & gas, petrochemical, power plants, chemical processing, and water treatment systems.
