摘要
聚乙烯(PE)管道已广泛应用于城镇中压燃气管网。本文基于PE管道安装特点,依据国家相关标准规定,结合实际工作经验,从资料审查、PE管材及管件质量检验、焊接质量检验、管道的埋深和敷设、定向穿越段质量检验、压力试验、质量保证体系实施状况评价等关键环节,指出了监督检验应注意的问题。
PE pipeline has been widely used in town middle pressure gas pipeline network.Based on the installation characteristics of PE pipeline,according to the relevant national standards,combined with practical work experience,the problems that should be paid attention to in supervision and inspection are pointed out from the key links of data examination,quality inspection of PE pipe and fittings,quality inspection of welding,buried depth and laying of pipeline,quality inspection of directional crossing section,pressure test and evaluation on the implementation of quality assurance system.
