What is a Socket Weld Full Coupling ？
The Socket Weld Half Coupling are often directly welded to the run pipe, to form a branch connection. Half coupling is socket welding in one end and butt welding for the another end. The Socket Weld Pipe Half Coupling are widely utilized in the aerospace industry as connectors to pressurize fuel piping. Various space shuttles have often had their launches delayed thanks to a half-coupling which needed closer inspection for safety reasons. A Socket Weld coupling may be a connector wont to screw two pieces of pipe together using threaded rings. Socket Weld Half-couplings are only threaded at one end. The opposite end is welded or otherwise fastened to the piping. Half-couplings are available male and feminine varieties. The male Socket Weld half-couplings have external threads that the pipe fits over. Female Socket Weld half-couplings have internal threads. The piping is inserted and twisted to secure the connection.
