摘　　要：介绍了长输管线中DN1 400供热管线管材的选择及壁厚的计算,对Q235B钢材及L290钢材性能做了简要的对比分析,指出目前供热管网的设计方式较多,主要有补偿、预热安装及无补偿冷安装等,无补偿冷安装敷设方式可以缩短施工周期,降低投资,减少占地,提高了管网的安全运行。This paper introduces the selection and calculation of the wall thickness of the DN1 400 heating pipeline in the long transmission pipeline,and makes a brief comparative analysis of the performance of the Q235 B steel and the L290. There are many ways to design the heating pipe network,mainly including compensation,preheat installation and non-compensation cold installation. The non-compensation cold installation and laying method can shorten the construction period,reduce investment,reduce the land area,and improve the safe operation of the pipe network.

关 键 词：集中供热 屈服强度 补偿冷安装 弯头
