Claims

[Scope of utility model registration request]

In an ultrasonic deep flaw apparatus for piping that detects flaws in a test tube by moving an ultrasonic probe in the circumferential direction and axial direction on the circumferential surface of the test tube, the above-mentioned both ends of an axle equipped with wheels at both ends A plurality of tubes are connected via connecting rods in a direction perpendicular to the axle, and a spring force is applied so that each connecting portion of the connecting rods is bent to the same side. a probe support that is rotatably mounted on a surface of the test tube in the circumferential direction of the test tube via the wheels, and that the ultrasonic probe is mounted on a specific axle so as to be movable in the axial direction; a first magnetic tape that is attached to the test tube so as to be attached to the probe support and stores information for evaluating the distance traveled by the probe support with respect to the test tube, and the probe; a circumferential position detection means comprising a first magnetic sensor disposed on a support and at a position facing the magnetic tape; and a circumferential position detection means provided on an axle on which the ultrasonic probe is mounted; a second magnetic tape storing information for evaluating the distance traveled by the ultrasound probe with respect to the probe support; and a second magnetic sensor that faces the magnetic tape and moves integrally with the ultrasound probe. 1. An ultrasonic deep damage device for piping, characterized in that it is equipped with an axial position detecting means.
