ABSTRACT:
An ultrasonic flaw detector is guided around a cylindrical pipe to be inspected by a cylindrical guide rail which is in the form of a split circular ring with a latch and a hinge. On the inner surface of the ring, geared bridge jacks are provided to secure the rings around the outer peripheral surface of the pipe. The ring is mounted to the peripheral surface of the pipe by turning a flexible wire rod connecting respective screws of the jacks. On the outer surface of the rings, a circular guide track and rack are arranged for engagement with the flaw detector.
