摘要
简要地探讨液化石油气贮罐母材中氢致分层类缺陷的超声波检测,对检测的几种超声波反射波形进行了分析,并给出了确定缺陷边界和深度范围的方法。
The paper briefly investigates the ultrasonic testing of hydrogen- induced cracking （HIC） for inservice LPG tanks , and analyses types of echo waves of the cracking. It also explains the methods how to fix the boundaries and depth ranges of HIC.
