特殊结构的常规和非常规超声检测

Conventional and Unconventional UT Techniques For Special Construction

研讨承压设备特殊结构常规和非常规体积检测方法(CI法),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国际法规、国际标准的水平再上新台阶。

Conventional and unconventional volumetric inspection techniques（computerized imaging techniques）for some special structure in pressure equipment are discussed,including 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,fill omissions and correct 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 international code and standards rise to a higher level.
