ABSTRACT:
The invention concerns a press for the testing by means of internal pressure of tubes provided with threaded ends, in which end pieces screwed in a pressure medium-tight manner on the tube ends are inserted into the sealing heads of the press. The end pieces are cap-like and have radially arranged connecting boreholes so that the pressure medium feed is radial in contrast to the axial pressure medium feed of the familiar constructions. No appreciable axial forces thus arise between the tubes and the test heads. In addition, the outer end of the cap-like end pieces facing away from the tube serves for the coupling of a shaft, which can displace the tube with the end piece axially and act upon it with a torque. Furthermore, the sealing head is readily detachable in a like manner in a retaining head and is inserted pressure medium-tight to the outside, just as the end pieces in the sealing heads.
