自八十年代中期从丹麦等北欧国家引进热水管道直埋技术后，该技术在我国已日趋成熟。但蒸汽管道直埋因其供热介质温度高，对其保温提出了更高的要求。本文简述了直埋蒸汽管道的保温、补偿、节点处理、支架设置等问题。 Since the introduction of hot water pipe direct burial technology from Denmark and other Nordic countries in the mid-1980s, the technology has matured in China. However, because of the high temperature of the heating medium, the direct burial of the steam pipeline puts forward higher requirements for its insulation. This article briefly describes the problems of thermal insulation, compensation, node handling, and bracket setup for buried steam pipes.
