Socket-Weld Valve End Connections

Socket-weld Valve End Connections. In this type, the ends of a valve are socketed to receive plain-end pipe. A circumferential weld is made on the outside of the pipe so that 'icicles' and weld spatter are unable to enter the pipeline. Socket-weld ends are used only on steel valves, and as a rule they are limited to sizes of 50mm and smaller for higher pressure/temperature applications in pipelines not requiring frequent dismantling.
