Abstract

OF THE DISCLOSURE TUBE WALL THICKNESS MEASURING APPARATUS 5 A tube wall thickness measuring apparatus which measures a wall thickness of a tube (52), includes an apparatus main body (3), a sensor (8) installed at the apparatus main body (3) and configured to generate an ultrasonic wave radially outward from a radial center of the tube (52), a pair of expansion/contraction mechanisms (4) installed at the apparatus main body (3) to be expandable and contractible radially outwardly and 10 radially inwardly and provided at regular intervals in a circumferential direction around an axis of the tube (52), a biasing member (5) configured to urge the expansion/contraction mechanism (4) to expand, wheels (6) installed at each of the expansion/contraction mechani sms (4) and configured to guide movement of the apparatus main body (3) in an axis direction (Da) while being in contact with an inner 15 circumferential surface of the tube (52), and a transmission mechanism (7) configured to convert a radial expansion of one (4a) of the expansion/contraction mechanisms into a radial expansion of the other expansion/contraction mechanism (4b). 20 (Fig- 2)
