ASME与DL/T 821—2002射线探伤标准在圆形气孔判定上的比较

The Comparison Between ASME and DL/T 821—2002 Radiographic Testing Standards in Determining Round Pore

分析比较了DL/T 821—2002《钢制承压管道对接焊接接头射线检验技术规程》与ASME锅炉压力容器规范等国内外射线探伤标准对气孔类缺陷的评定标准,结合理论和实际解剖,提出了对于圆形气孔缺陷判定的建议。

Through the analysis and comparison among radiographic testing standards at home and abroad, such as DL/T 821--2002, the technical regulations of radiographic examination of butt welded-joints of pressure steels pipes and tubes, and ASME boiler and pressure vessel and so on, combining with the theory and practical operating, suggestions about how to determine round pore defects was proposed.
