发明名称 Pipe tester with multiple fluid source connections
摘要 Apparatus is disclosed for hydrostatically testing a length of pipe wherein the pipe is adapted to be closed by plugs at each end, one of the plugs having a port to which a hose leading from a pump may be connected in order to fill the pipe with water, and the other plug having a bleed valve through which air may be vented from the pipe as it is filled. Pump pressure is applied to the water in order to test the pipe, and water is then drained from the pipe to permit the pump hose to be disconnected from one plug for use in testing another length of pipe.
