特殊结构的常规和非常规超声检测——ASME 2013 NDE亮点评析

Evaluation on Highlight of NDE in 2013 ASME Code: Conventional and Unconventional UT Techniques For Special Construction

重点评析ASME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(CI法)的亮点,包括堆焊层、小径管、管接头之类检测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。企望通过研讨,对照国标行标企标,对照国情行情,找差距、纠偏误,在承压设备NDE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 highlight 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 ifnd a gap and ifll in the blank, ifll omissions and correct errors in this ifeld, so that we can, on the path of NDE development towards high-end, high quality and high efifciency, make the Chinese enterprise performing the referencing ASME Code Section rise to a higher level.
