输气工艺管道焊接质量检验批管理探讨

Discussion on Batch Management of Gas Transmission Process Pipeline Welding Quality Inspection

管道焊接质量关系投产后场站安全运行,对焊接质量的评定均以对检验批的检查、检验结果为依据。对管道组对、焊接的检验批的相关规定进行了梳理,明确了管控重点,确定了检验批的选取准则和检验合格标准,分析了存在的问题,为输气工艺管道焊接质量验收管理提供了准确、全面的依据。

The welding quality of pipeline determines the safe operation of the gas transmission stations after putting into operation,and the evaluation of welding quality is based on the inspection results of the inspection lot.The relevant regulations of welding pipeline pair and inspection lot were sorted out,the key points of welding quality control were clarified,the selection criteria and inspection standards of inspection lot were determined,and the existing problems were analyzed,which provided an accurate and comprehensive basis for welding quality acceptance management of gas transmission process pipeline.
