ABSTRACT:
Pressure test apparatus for testing heat exchanger tubing is disclosed, and the preferred embodiment includes pressure inlet and pressure outlet means for connecting to the open ends of heat exchanger tubing. The apparatus utilizes a quick disconnect mechanism for tubing which is pressure actuated by introducing water under pressure, the water flowing into the tube and maintaining continued pressure to thereby test the tubing for leakage. For fitting around the end of the tubing, the invention thus discloses a surrounding cylindrical body which is counterbored to an internal cavity which receives a set of collets which surround the end of the pipe. The collets collectively are abutted by a pressure transmission ring at the end, the ring being exposed to the water pressure. As the water pressure increases, the collets are driven into a wedged position, jamming against the pipe to be held in the test apparatus.
