?Compared with the traditional trench laying pipeline, it has the advantages of good thermal insulation perbance, less construction and installation area, low construction cost and short construction cycle, especially in energy saving. As far as the current situation is concerned, it is incomparable with any thermal insulation pipeline. In the pipeline with a depth of about one meter, the cooling rate is 0.1 C for every 100 meters and the heat loss rate is 2.07% for every 100 meters. In general, 10.4 tons of standard coal can be saved annually in a kilometer thermal insulation pipeline. Comparing with other thermal insulation materials, rigid polyurethane foam is a kind of good thermal insulation material. The bubble is closed-cell structure, and the thermal conductivity (0.007W/m.K) of the gas (Freon F11) in the closed-cell is very small. Therefore, the thermal insulation perbance of polyurethane direct-buried thermal insulation material is lower than a few. Other insulation materials, compared with other insulation materials, to achieve the same insulation, insulation thickness can be reduced by 30-80%. High density low pressure polyethylene (HDPE) outer protective layer polyurethane direct buried insulating pipe overview of HDPE outer protective layer polyurethane direct buried insulating pipe energy-saving direct buried insulating pipe is composed of steel pipes, anticorrosive coating, insulation layer, anticorrosive and compressive protection layer, if it is ultra-high temperature pipeline, in the insulation layer and anticorrosive layer in the middle of a cooling layer. These pipes have the advantages of less heat loss, better compression resistance and better waterproof and corrosion resistance. Usually the service life is about 40-50 years. Polyurethane insulated buried pipe has become a mature advanced technology in some developed countries abroad. In the last decade or so, through digestion and absorption of this advanced technology, heat supply engineers and technicians in China are pushing the domestic pipe network laying technology to a higher level. The practice results over the past decade have fully proved that the polyurethane thermal insulation buried pipe laying b has many advantages compared with the traditional trench and overhead laying. This is also the internal driving force for the rapid development of the thermal insulation directly buried pipe of polybutyric cheese.
