ABSTRACT:
A pressure die having a base portion with an entrance block and an exit block attached thereto. The entrance block and exit block each have a groove adapted to receive the pipe. The curvilinear geometry of the groove of the exit block is constant so that the exit block is symmetrical and can be attached to the base portion in either a first position or a second position in which the exit block is rotated 180 degrees. The exit block is mounted onto the base portion at an angle so that the entrance portion of the exit block is lower in elevation than the exit portion of the exit block. The angle allows for a smooth transition from clearance to compression between the pipe and surface of the groove.
