【Abstract】 The insulation state of heating pipeline of a heating company is tested in Daqing City,and there are some problems are found. The selection of insulation material and design of insulation layer thickness is unreasonable. Some heating pipes insulating layer thickness are optimized and transformed,and compared the heat loss of the pipeline before and after transformation by testing . The results show that the heat loss decreased by 90% per unit area after transformation.更多还原
