分析了管壁中的应力分布与管道破裂的规律 ,在此基础上 ,指出了制定管道探伤工艺时应注意的几个原则问题。讨论了通过断裂力学计算来确定探伤判废标准的方法 Based on the analysis of the stress distribution in the pipe wall and the rupture of the pipeline, several principle problems that should be paid attention to in the development of pipeline flaw detection technology are pointed out. Discusses the method of fracture mechanics calculation to determine the standard of detection and rejection
