Abstract
An apparatus for examining a circumferential surface of each of a plurality of tubular members disposed in axially parallel relationship with each other has a rail adapted to extend between adjacent tubular members; a truck movable on and along the rail, a support frame having mounts at each end tiltably mounting the support frame on the truck for tilting around an axis extending along the rail, and a tilting mechanism connected to the support frame for tilting the support frame. A semi-circular shaped beam is mounted on the support frame for rotation around an axis through the center of the circle on which the semi-circular shaped beam lies and open laterally of the rail, and a sensing element is disposed at a predetermined position on the semi-circular shaped beam. The semi-circular shaped beam is tilted down by tilting the support frame when the truck is moved along the rail from one tubular member to the next, and is tilted up so as to partially surround the tubular member for carrying out the examination.
