るゲート回路と を具備することを特徴とする超音波探傷装置。[Scope of Claim for Utility Model Registration] An ultrasonic flaw detection device that inspects pipes for defects from the inner surface, comprising a transmitting transducer and a receiving transducer tilted at the same angle in the circumferential direction of the pipe with respect to the normal to the inner surface of the pipe. The vertical probe is tilted at the same angle in the axial direction of the tube with respect to the normal to the inner surface of the tube, and the ultrasonic wave is propagated in the circumferential direction of the tube, and the ultrasonic wave is propagated around the inner circumference of the tube in order to receive the reflected wave. A bevel probe having a transmitting transducer and a receiving transducer tilted with respect to the surface, and housing the vertical probe and the bevel probe, and also matching the curvature of the inner surface of the tube. a probe holder having a shaped shoe; an oscillator that applies a high frequency to a transmitting transducer of each of the vertical probe and the angle probe; and a receiver of the vertical probe and the angle probe, respectively. A signal processing circuit that processes reflected echoes detected by the vibrator, and a gate circuit that sets gates for distinguishing reflected echoes from defects captured by the vertical probe and the oblique probe, respectively. An ultrasonic flaw detection device characterized by:
