ULTRASONIC PROBE HOLDER, ULTRASONIC FLAW DETECTOR, AND ULTRASONIC METHOD FOR DETECTING FLAW IN TUBULAR BODY

PROBLEM TO BE SOLVED: To provide an ultrasonic probe holder capable of efficiently performing ultrasonic measurements on a tubular body without the need for skill. SOLUTION: The ultrasonic probe holder 1 comprises both a holding part 2 for holding a probe 4 and a holding claw part 3 provided for both right and left sides of the holding part 2. A part (contact part) 2a of the holding part 2 to be in contact with the tubular body T, a body to be inspected, has the same curvature as the outer diameter of the tubular body T and comes into close contact with the outer circumference of the tubular body T. The contact part 2a is brought into contact with the outer circumferential surface of the tubular body T at inspection as shown in Fig. 1, and the tubular body T is sandwiched by a roller 8 of the holding claw part 3 from both sides to maintain the close contact between the tubular body T and the holding part 2.
