摘　　要：热熔对接焊是聚乙烯(PE)燃气管道铺设过程中最重要的环节,其焊接质量的优劣直接影响整条输送线路的安全,因此PE燃气管道热熔对接焊工艺的标准化具有重要的意义。文中介绍了美国现行标准ASTM F2620-13、德国现行标准DVS 2207-1和欧盟现行标准ISO 21307等3个国外PE燃气管道热熔对接焊标准;介绍了国家质检总局标准TSG D2002—2006和建设部标准CJ J 63—2008两个国内PE燃气管道热熔对接焊标准。重点对国内外现行标准的特点及工艺进行分析与比较,旨在促进我国PE燃气管道热熔对接焊国内标准的发展和国家标准的建立。The heat fusion butt welding of polyethylene(PE) gas pipes is the most important part in the process of laying the PE gas pipelines,which will directly affect the safety of the entire gas distribution lines.Therefore the standardization of heat fusion butt welding of PE gas pipes has great significance for their extensive applications.In the paper,three current overseas standards and two current domestic standards of the heat fusion butt welding of PE gas pipes,such as US ASTM F2620-13,German DVS 2207-1,ISO 21307,TSG D2002—006 of AQSIQ and CJ J63—2008 of Ministry of Construction P R C are introduced,and then the characteristics of above five standards was compared and analyzed specially in order to promote the development of domestic standards and the establishment of national standards.
