Socket Weld flanges were initially developed for use high pressure piping

　　The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.

　　ASME B31.1 1998 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assembly of the joint before welding, the pipe or tube shall be inserted into the socket to the maximum depth and then withdrawn approximately 1/16" (1.6 mm) away from contact between the end of the pipe and the shoulder of the socket.

　　We are engaged in manufacturing of a wide range of Butt Weld Fitting that is available in varied types such as steel elbow, tee, concentric and eccentric reducers, carbon steel pipe fitting, cross and caps. Sourced from reliable vendors, these fittings are highly acknowledged for their high tensile strength, durability and accurate alloy composition. These find application in several industries such oil & gas, automobile, acid & chemical, pharmaceutical and cement industries. We are known for our butt welding fitting pieces.
