ABSTRACT:
Apparatus for testing a pipe under internal fluid pressure for leakage or structural integrity includes an elongate, hollow mandrel having one end sealed by a fixed seal. A shiftable seal is adapted to advance a pipe to be tested so that the other end of the mandrel is inserted through one end of the pipe to a testing position. The shiftable seal includes a pressure plate and a plug, the pressure plate sealing the other end of the pipe and the plug insertable within the other end of the mandrel for sealing it when the mandrel is in the testing position. The shiftable seal further includes a frame assembly movable along tension beam members, the assembly being selectively lockable thereto. The pressure plate is mounted on the assembly and is adapted to be selectively extended from or retracted toward the assembly.
