Socket-Weld

Socket-Weld flanges feature a recessed socket that allows the pipe to be inserted directly and secured by external welding. This design makes Socket-Weld flanges particularly suitable for small diameter, high-pressure piping systems. They have a simple structure that is easy to install, but precise welding techniques are required to ensure sealing and strength.

Socket-Weld offers good fluid sealing performance and is suitable for high-pressure environments. However, compared to butt-weld flanges, socket-weld flanges may be more complex to assemble and weld, and the welding process may cause pipe deformation.
