保温钢管钢管在国外一些兴旺国度已成为一项比拟成熟的先进技术。近十几年，我国供热工程技术人员经过消化、吸收这项先进技术，正推进着国内管网敷设技术向更高的层次开展。十几年来的理论成果充沛证明了聚氨酪保温直埋管敷设方式与传统的地沟及架空敷设相比，聚氨酯发泡保温管具有诸多优点。直埋式保温管是由保送介质的钢管，高密度聚乙烯外套管，以及钢管和外套管之间的硬质聚氨酯泡沫保温层严密分离而成。
Polyurethane insulation pipe in some developed countries has become an advanced technology mature. In recent years, China's heating engineering technical personnel after digestion, absorb the advanced technology, promote domestic pipeline laying technology development to a higher level. Theoretical results ten years fully proves that compared polyurethane insulation pipe laying mode and traditional cooking and overhead laying, polyurethane foam insulation pipe has many advantages. Directly buried insulating pipe is made of steel pipe conveyor medium, high density polyethylene jacket pipe, and rigid polyurethane foam between the steel tube and the outer tube of the heat preservation layer and strict separation.
保温钢管钢管又称“管中管”其有“两步法”构成，是由高密度聚乙烯外维护层、聚氨酯硬质泡沫塑保温资料和钢管组成。 保温层资料为密度60kg/m3至80kg/m3的硬质聚氨酯泡沫，充沛添满钢管与套管之间的间隙，并具有一定的粘接强度，使钢管、外套管及保温层三者之间构成一个结实的整体。 聚氨酯直埋保温管泡沫具有良好的机械性能和绝热性能，通常状况下可耐高温120℃经过改性或与其它隔热资料组合可耐高温180℃，适用于各种冷、热水上下温管道的保温工程。当然硬质聚氨酯保温管价格决定着质量的好坏
Thermal insulation pipe is also known as the "tube" of its "two steps", is made of high density polyethylene outer protective layer, rigid polyurethane foam plastic insulation materials and steel pipes. Rigid polyurethane foam insulation layer data for the density of 60kg/m3 to 80kg/m3, the gap between the steel tube and full Tim full casing, and has a certain adhesive strength, which constitute a strong overall between the steel tube, the outer tube and the heat preservation layer three. Polyurethane direct buried insulation pipe foam has good mechanical performance and heat insulation performance, usually under the condition of high temperature of 120 ℃ after modification, or with other insulation data combination can withstand high temperatures of 180 ℃, heat preservation engineering applied to the temperature of all kinds of cold, hot water. Of course, the rigid polyurethane insulation pipe price determines the quality of the
高密度聚乙烯夹克保温管预制直埋聚氨酯发泡泡沫直埋保温管有非常突出的优点：
