Abstract
PURPOSE: To measure the incident point in the circumferential direction of pipe and the bending angle accurately, by providing internal bent grooves and through- holes in the face and back of a disc having the same curvature as the contact face of the probe with the shoe, and reflecting ultrasonic beam from the probe.
CONSTITUTION: In the face and back of a disc having roughly the same curvature as the pipe and made of the same material are provided internal bent grooves U1, U2 for measuring the incident point, and corresponding straight grooves C1, C2, and also provided are notch 10 and holes d3 to d5. And the notch surface of the notch part 10 composed into a reflecting plane R. Furthermore, measurement direction lines S1 to S5 are drawn from the measuring points i1 to i5 in the circumference of the face and back towards the internal bent grooves U1, U2 and holes d3 to d5 so as to prevent the inspector from making mistake in the flaw detection direction. In the measurement of incident point, the probe is moved in the cirvumferential direction in the vicinity of measuring point i1 when the beam path is short, or in the vicinity of i2 when it is long, and the position of the highest reflection is selected by U1 or U2. In the measurement of bending angles of 45°, 60°, and 90°, the probe is moved to i3 to i5 respectively, and the light is reflected by the plane R, then the position of the highest reflected waves from holes d3 to d5 is selected.
