摘要
超级奥氏体不锈钢压力管道经射线检测发现未熔合缺陷,由于缺陷自身高度难以定量,检验人员应用TOFD检测对未熔合缺陷自身高度进行测定,根据检测结果对压力管道安全等级进行评定并提出相应处理措施,管道缺陷部位解剖后证实检测数据的准确性。
Super austenitic stainless steel pressure pipe by ray testing found that lack of fusion defects, defects due to its highly difficult to quantify, detected by TOFD inspection personnel to lack of fusion defects of its height were determined, according to the detection results of safety grade of pressure pipeline assessment and puts forward the corresponding treatment measures, the pipeline defects anatomic confirmed the accuracy of detecting data.
