摘要： A device for determining the shape of the inner wall of a tube, particularly at the level of a weld. A measuring device is arranged in the tube enabling the distance separating a given point situated on the inner wall of the tube and the longitudinal axis of this tube to be read. The measuring device is movable in the tube so as to read off successive dimensions of such point in the course of its displacement, the movement of the measuring device being such that the point so measured is displaced longitudinally in an alternating movement over a constant distance, and displaced simultaneously in slow rotation around the longitudinal axis, the reading of the measurements being completed when the point measured has carried out at least one complete revolution in the tube. The invention is useful in checking the tubes of a steam generator.
