摘　　要：结合某长输热网供热工程,对架空热水供热管道的保温技术进行探讨。保温管采用外护管为镀锌钢管(由螺旋咬口工艺制备)的预制保温管。滑动支架采用隔断式绝热支架,主要装置为预埋件、箱型管托、滑动底板(镶嵌聚四氟乙烯板)。固定支架采取整体保温的方式。经实际测量,滑动支架、阀门表面温度比较高,保温效果仍有提高的空间。Combined with a project of long-distance heating network,the insulation technology of the overhead hot water heating pipeline is discussed. The insulation pipe is prefabricated insulation pipe with galvanized steel for external protection,which was prepared by the spiral seam process. The sliding bracket is partition type insulation bracket,the main device is embedded part,box-type tube holder and sliding plate with PTFE plate. The fixed bracket is integral insulation. By actual measurement,the surface temperature of sliding bracket and valve is relatively high,and the insulation effect still has room for improvement.
