摘　　要：本文论述了不同直埋敷设热网的情况。针对这些情况,热力和蒸汽管网的工作钢管可能采用不同的补偿方式。在该补偿方式下,分析热网所受热应力的状况及整个热网的运行状态。文中提出了宜使用的补偿方法,同时针对蒸汽管网提出了不同补偿器的特点和适用范围。This paper discusses the situation of the different buffed insulation pipe. Aiming at these situations, working steel pipe of heat and steam pipe network may use different compensation methods. In this compensation mode, the thermal stress on the heating network and the running status of the entire heating network are analyzed. In this paper, the compensation method should be adopted. At the same time, for the steam pipe network, the characteristics and applicability of different compensators are put forward.
