What is a SW fiting?
Socket welding (SW) is used for welding pipes and fittings including reducers, tees and elbows. Socket weld pipe fittings are used to permanently join pipes that are inserted into a recess in the fitting, flange or valve. Once correctly inserted, fillet type sealing welds are applied to join the pipe to the fitting.
