摘　　要：结合某长输供热管网工程,对长输热网特殊节点处理及保温管道设计进行探讨。特殊节点包括穿越城市道路、铁路、河流节点。保温管道设计主要涉及工作管钢材、壁厚选型以及外护层、保温层制造工艺的选择。Combined with a long-distance heating network project,the treatment of special nodes in the long-distance heating network and the design of insulated pipeline are discussed. Special nodes include crossing urban roads,railways and rivers nodes. The design of insulated pipeline mainly involves the selection of working pipe steel and wall thickness,and the selection of outer protective layer and thermal insulation layer manufacturing technology.
