A Flange is a plate or a ring which is fastened at the end of the pipe forming a rim that can be used to connect pipes or fixed to an inlet or outlet unit. The Socket Weld Flanges are used on the smaller size of high-pressure pipes. The flanges are attached by inserting the pipe into the socket end and held firmly by applying fillet weld around the top. The socket weld has an internal recess on the inside diameter which is provided to allow free flow of process liquid or gas inside the pipe.
