摘要： PROBLEM TO BE SOLVED: To automatically determine whether a tube is normal, by integrally evaluating the thickness data of a plurality of spots. SOLUTION: The thickness of the tube at each spot is measured with the ultrasonic flaw detection method, and the measured data are recoded in the memory device. The evaluation is started by reading the recoded data in the computer. Related to the thickness data which is smaller than a predetermined thickness threshold level, it is determined that whether it is normal or that reevaluation is needed, by evaluating the axial direction based on a plurality of thickness data. Similarly, related to the thickness data, it is determined that whether it is normal or re-evaluation is needed by evaluating the circumferential direction, based on the plurality of thickness data. Furthermore, by evaluating the stress of the least thickness part, it is determined that whether it is normal or reevaluation is needed. Related to the thickness data which is determined that the reevaluation is needed, pitting evaluation is performed, and finally it is determined that whether the tube is normal or abnormal.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic inspection device capable of measuring the size of a flaw on an inspection object portion by correcting an error of an ultrasonic beam path length caused by a curvature of the surface of the inspection object.
SOLUTION: An SV wave propagating just under the surface of the inspection object 11 is transmitted from either of two ultrasonic probes 12a, 12b arranged at a prescribed interval on the surface of the inspection object 11 and received by the other, to thereby measure the ultrasonic beam path length by an ultrasonic beam path length measuring means 14. On the other hand, a correction operation means 18 calculates the ultrasonic beam path length by the surface shape of the inspection object 11 based on curved surface data measured by a curved surface data measuring device 20. A flaw measuring means 16 corrects the ultrasonic beam path length by adding the ultrasonic beam path length by the surface shape of the inspection object 11, and compares it with an ultrasonic beam path length in the case where the inspection object portion between the two ultrasonic probes 12a, 12b has no flaw, to thereby measure the flaw size.
