【摘要】：使用HS610e型數(shù)字式超聲波探傷儀配合單晶縱波斜探頭,對(duì)專門制作的奧氏體不銹鋼對(duì)接焊接接頭試塊研究超聲波檢測(cè),得到了典型缺陷的超聲檢測(cè)圖幅。利用實(shí)驗(yàn)結(jié)果,對(duì)某煉油廠220萬t/年加氫裝置高壓管道奧氏體不銹鋼焊縫進(jìn)行了檢測(cè),取得了良好的結(jié)果。
[Abstract]:Using HS610e digital ultrasonic flaw detector and single crystal longitudinal wave oblique probe, the ultrasonic testing of austenitic stainless steel butt welded joint is studied, and the ultrasonic inspection map of typical defects is obtained. Based on the experimental results, the austenitic stainless steel welds in the high pressure pipeline of a 2.2 million t / year hydrogenation unit in a refinery have been tested and good results have been obtained.
