ABSTRACT:
A supporting fixture for pipe to be pressure-tested. The fixture includes a cage-like structure to receive an elbow, the structure being composed of opposing cage-like cradle segments defining a pipe elbow enclosure. The ends of the segments have respective semicircular flange portions to which is bolted a disc for sealing the end of a pipe elbow received in the enclosure. In the case where the elbow has a length of pipe attached thereto, a two-segment retaining cage structure is employed for the free end portion of the pipe section, also having a disc bolted thereto for sealing the pipe, the segments of the said latter retaining cage structure being connected to the elbow cage by tie rods. In the case where two elbows are joined by an intervening length of pipe, two elbow-retaining cage structures are employed, connected by tie rods. The elbow cage segments may be hinged together.
