ABSTRACT:
A portable apparatus for nondestructive ultrasonic inspection of oil field tubular goods includes a deck which mounts spaced drive rollers for rotating the pipe being inspected. A substantially box-shaped carriage moves on tracks above the pipe to allow a pair of ultrasonic inspection wheels to traverse the pipe. The combination of pipe rotation and carriage movement causes the inspection wheels to trace helical paths on the surface of the pipe. In an alternative embodiment, the rotating pipe is drive longitudinally through stationary ultrasonic equipment. A programmed control system and a method of ultrasonic inspection also are disclosed.
