油气长输管道与城镇燃气管道焊接检验研究

摘要

Though comparison of domestic and international design codes of oil & gas transmission, pipeline inspection standards and methods suitable for domestic pipelines were proposed. Welding quality inspection standards for oil & gas transmission pipeline and city gas pipeline were comparatively analyzed. It's pointed out that welding quality inspection standard for city gas pipeline is more stringent than that of oil & gas transmission pipeline.%通过对比国内外油气长输管线设计觃范，提出了较适合国内管线焊缝检测要求及方法。还对油气长输管线及城镇燃气管线焊缝检测质量标准迚行了对比分析：城镇燃气管线焊缝质量要求要高于油气长输管线的质量要求。
