摘要
压力管道按属性和用途分类,可分为工业、公用及长输管道,其焊接接头射线检测执行标准涉及NB/T 47013.2,GB/T 12605及SY/T 4109,此三项标准在检测适用性、检测工艺及检测质量分级等方面存在一定区别,系统比较并分析了其相关特点和差异,为从事压力管道设计、施工、检测及建造监督的相关人员提供参考,尤其建议设计和业主者应对上述标准进行综合选用。
Pressure pipelines are classified into industrial,public,and long-distance pipelines based on their properties and uses.The radiographic testing standards for their welded joints involve NB/T 47013.2,GB/T 12605,and SY/T 4109.There are certain differences among the three standards in terms of testing applicability,testing process,and testing quality grading.This paper systematically compared and analyzed the relevant characteristics and differences,providing reference for personnel engaged in pressure pipeline design,construction,testing,and construction supervision,especially reminding designers and owners to comprehensively select the above standards.
