A socket weld flange is a type of pipe connector that incorporates a socket into which a pipe is welded. The inclusion of a socket in the socket weld flange creates a connection that is much stronger than a comparable slip-on flange. The socket weld flange was designed to work on small size, high-pressure pipelines. This flange is very popular in chemical plants where a smooth-flowing connection is needed in all flange joints. The benefit of a flanged connection is that the pipe can be easily disconnected at the flange and reassembled just as easily.
