预制直埋热水保温管Prefabricated Heat Insulation Pipes 直埋预制保温管由输送介质的钢管,聚氨酯硬质泡沫保温层和高密度聚乙烯外套管紧密结合而成,该产品主要用于城 镇集中供热管网,石油输送管线,高寒地区输水管线及厂区工业管道工程,它具有高效保温、防水防腐和施工简便,不怕 植物根刺的优点,施工不需地沟敷设,能在0.6-1.2米冻土层内直埋,热损失比传统工艺可降低40%,使用寿命比其他绝热 防腐材料提高3-5倍以上,使用寿命可达30-50年。 Direct-buried prefabricated thermal insulation pipe is made by closely attach- ing the transm- ission medium of steel pipe ,polyurethane hard foamed thermal insulation layer and HDPE outer casing This project is mainly used on urban central heating networks, petroleum transmission pipelines , water supply pipe- lines in high and cold areas and industrial pipeline projects in factory areas . It has the advantages of highly effective thermal insulation,water resistance and corrosion resis- tance and resistance to puncture by plant roots. Trench laying is not required during construct- ion and it can be directly buried in the frozen earth layer 0.6to 1.2m deep。The amount of thermal loss can be reduced by 40%as compared with the traditional process. Its service life can reach 30 to 50 years, which is 3to 5 times longer than other thermal insulat-ion and corrosion resistant materials.
