摘　　要：重点评析了ASME NDE最新版(2013)第Ⅴ卷《无损检测》中涉及承压设备特殊结构常规、非常规体积检测方法(计算机成像技术)的亮点,包括堆焊层、小径管、管接头之类检测时有一定难度的规范要求、施探要领和典型案例,突出扫查建模仿真和检测特性验证的重要性。通过对照国标、行标、企标,结合国情行情,找差距、纠偏误,在承压设备无损检测向高端、高质、高效发展的方向上,使中国企业正确执行ASME有关规范的水平更上一个台阶。This article presents an evaluation on the key requirements of the updated ASME Code（2013）,Section Ⅴ NDE,in terms of conventional and unconventional volumetric inspection methods（computerized imaging techniques）for some special structure in pressure equipment,such as weld metal overlay cladding,nozzle welds and small diameter tubes and so on,highlighting the importance of modeling scan and performance demonstration.Through discussion,comparing our industrial standards and enterprise standards with the international Code,and looking at our national condition and company status,we may expect to find a gap and fill in the blank,correct omissions and errors in this field,so that we can,on the path of NDE development towards high-end,high quality and high efficiency,make the Chinese enterprise performing the referencing ASME Code Section rise to a higher level.
