ABSTRACT:
A method for testing the integrity of a weld on a pipe includes the application of an axial stress on the weld during the integrity test. Ali assembly for performing the method is also provided, wherein a pair of circumferential supports are provided on the pipe on opposite sides of the weld, and between which extend axial force applying devices. In one aspect, the invention is used to test a weld securing a flange to a pipe. The invention also provides novel circumferential clamps for securing to the exterior of pipes.
