This standard applies to the threaded connections of pipes, valves, pipe joints, cocks and other pipeline accessories. If the connection is required to be sealed, the sealing surface structure should be designed outside the thread. Add suitable sealing medium to the sealing surface, and use the thread to lock and seal the sealing surface.
