Description

Technical Field

[0001] The utility model relates to the field of pipeline maintenance, in particular to a new half joint. Background Art

[0002] The half joint is a pipe leak stopper. The half joint and the socket half joint are pipe repair devices. The socket half joint is used to repair leaks at the socket where two pipes are connected. The half joint is used to repair parts other than the socket.
