A182 F91 Socket Weld Elbow ,known as SW elbow, which is one type of ASME B16. 11 Pipe Fittings and widely used in oil & gas, petrochemical, chemical processing.
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.
ASME B16.11 A182 F91 socket weld elbow is available in 90 degree and 45 degree.
