Abstract
An apparatus for X-ray testing of pipes following ultrasonic testing includes a reversible roller track for telescoping a pipe upon a cantilever arm which can be moved up and down on a stand and carrying an endless belt with resilient U-shaped holders for supporting film strips to be moved into the pipe and adjacent to suspected defects. Reversal of the belt drive permits removal of the exposed film strips as the pipe is moved out.
