ABSTRACT:
External pipe testing apparatus is disclosed as comprising semi-cylindrical housing sections hingedly connected for swinging between an open position to permit the housing to be moved into and out of a position about a section of the pipe to be tested. When the pipe sections are locked to one another, seal strips mounted on the inside of each housing section are caused to sealably engage with one another and the ends of the pipe section to form an annular test chamber about the pipe section.
