爆炸焊不锈复合钢制压力容器和封头RT底片显示的波状“裂纹”问题已困扰压力容器行业多年并常引起争议。通过大量试验分析 ,证实所谓“裂纹”的问题主要是爆炸焊不锈复合钢板一种固有的“缺欠” ,不是加工变形制造、焊接等所至 ,希望与制造、监督检验、使用单位等有个共识 ,并供制修订“承压设备无损检测”等法规标准时的参考
The problem of wavy “cracking” of the explosion-welded stainless steel composite pressure vessel and head RT negatives has plagued the pressure vessel industry for many years and often causes controversy. Through a large number of tests and analysis, it is confirmed that the so-called “crack” is mainly caused by an inherent “deficiency” of the explosion-welded stainless steel composite plate, which is not caused by manufacturing, welding, and so on. It is hoped that there will be a Consensus, and for the revision of “pressure equipment non-destructive testing” and other regulatory standards for reference
