About Socket Fittings | Cross | A105
This fitting design has a socket or recess for the pipe to slip into. A back weld is applied to hold the pipe in the fitting. Socket Weld fittings are formed by using either the drop forge or upset forging method. They are forged solid and require complete machining. Similar to the preparation of Socket Weld Flanges, an expansion gap of 1/16 inch (1.6 mm) between the pipe and the shoulder of the socket must be ensured by the welder. ASME B31.1 para. 127.3 Preparation for Welding (E) Socket Weld Assembly says: In assembly of the joint before welding, the pipe or tube shall be inserted into the socket to the maximum depth and then withdrawn approximately 1/16" (1.6 mm) away from contact between the end of the pipe and the shoulder of the socket. Materia: Forged A105
