ABSTRACT:
The invention contemplates removable end-closure structure for sealed application to the end of a pipe of given outside diameter for hydrostatic pressure-testing the pipe. In the form disclosed, a circumferential wedge clamp is applied to the outer surface of the pipe end to be closed; a closure plate is applied in axial abutment with the pipe end; and a hydraulic flat jack is interposed between the closure plate and an outer reference or backing plate having circumferential connection to the wedge clamp. All parts may be in unit-handling relation, even when not mounted to a pipe end.
