它與傳統(tǒng)的地溝敷設管道相比,具有保溫性能好、施工安裝簡便占地面積少、工程造價低、施工周期短等優(yōu)點,特別是在節(jié)能方面,以目前情況而言,是任何保溫管道難以比擬的,據天津市節(jié)能技術服務中心測試報告指出:在直埋深度約為一米的管道里,每100米降溫為0.1℃,每100米長的熱損失率為2.07%,一般情況下一公里保溫管道中,每年可節(jié)約省標準煤10.4噸。聚氨酯直埋保溫管材料與其他保溫材料保溫性能之比較硬質聚氨酯泡沬塑料是一種性能良好的保溫材料,泡孔呈閉孔結構,閉孔中的氣體(氟里昂F11)導熱系數(0.007W/m.K)極小,因此,聚氨酯直埋保溫管材料的隔熱性能低于幾乎所的的其他保溫材料,它與其他保溫材料相比,達到同樣的保溫,絕熱層厚度可以減小30-80%。高密度低壓聚乙烯(HDPE)外護層聚氨酯直埋保溫管概述HDPE外護層聚氨酯直埋保溫管概述節(jié)能直埋保溫管道由鋼管、防腐層、保溫層、防腐抗壓保護層組成,如果是超高溫管道,則在保溫層和防腐層中間再加一降溫層。這些管道具有熱損失少抗壓性能強、防水防腐性能好等優(yōu)點。使用壽命一般在40-50年左右,聚氨酯保溫直埋管在國外一些發(fā)達國家已成為一項比較成熟的先進技術。近十幾年,我國供熱工程技術人員通過消化、吸收這項先進技術,正推動著國內管網敷設技術向更高的層次發(fā)展。十幾年來的實踐成果充分證明了聚氨酪保溫直埋管敷設方式與傳統(tǒng)的地溝及架空敷設相比,具有諸多優(yōu)點。這也正是聚氨酪保溫直埋管在我國供熱工程上得以迅猛發(fā)展的內在動力。
?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.
