ABSTRACT:
A pipe test disk has a planar disk portion having a lower circumferential edge portion which is joined to a pipe end and an upper circumferential edge portion which is joined to a fitting, a center portion through which an opening is formed for inlet of fluid to pressurize the pipe for testing, and a coupling pipe portion surrounding the center portion and extending upwards from the disk portion for coupling to an external fluid pressurizing apparatus. The pipe end, test disk, and fitting are solvent welded together. When the testing is completed, the coupling pipe portion is broken off and the disk portion is cut out to leave an open passage between the pipe end and the fitting.
