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.

解决方案：用超声波探伤法测量每个点处的管的厚度，并将测量数据在存储器件中重新编码。通过读取计算机中的重新编码的数据开始评估。与厚度数据相比，通过基于多个厚度数据评估轴向方向，确定是否正常或需要重新评估。类似地，与厚度数据有关，基于多个厚度数据，确定是否需要通过评估圆周方向是正常的或重新评估。此外，通过评估最小厚度部分的应力，确定是否需要正常或重新评估。与确定需要重新评估的厚度数据相关，进行点蚀评估，最后确定管是正常还是异常。版权所有（C）2009，JPO＆INPIT
