預(yù)制直埋熱水保溫管Prefabricated Heat Insulation Pipes 直埋預(yù)制保溫管由輸送介質(zhì)的鋼管，聚氨酯硬質(zhì)泡沫保溫層和高密度聚乙烯外套管緊密結(jié)合而成，該產(chǎn)品主要用于城 鎮(zhèn)集中供熱管網(wǎng)，石油輸送管線，高寒地區(qū)輸水管線及廠區(qū)工業(yè)管道工程，它具有高效保溫、防水防腐和施工簡便，不怕 植物根刺的優(yōu)點，施工不需地溝敷設(shè)，能在0.6-1.2米凍土層內(nèi)直埋，熱損失比傳統(tǒng)工藝可降低40%，使用壽命比其他絕熱 防腐材料提高3-5倍以上，使用壽命可達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.
