对于钢管内的分层缺陷,许多探伤方法缺少检出能力,用超声波探伤法不但可以对在役小口径薄壁管中分层缺陷进行检测,还可以检测钢管壁厚。
For stratified defects in pipe, many flaw detection methods lack the ability to detect, with ultrasonic flaw detection not only in-service small-diameter thin-walled tube delamination defects detected, but also can detect the wall thickness.
