              1. It has strong corrosion resistance and waterproof ability and low comprehensive cost
              According to the calculation of relevant departments, under normal circumstances, the double pipe heating pipeline can reduce 25% of the project cost (using glass fiber reinforced plastic as the protective layer) and
              About 10% (HDPE is used as protective layer).
              2 、防腐,絕緣性能好,使用壽命長
              2. Anticorrosion, good insulation and long service life
              The insulation pipe is tightly adhered to the outer skin of the steel pipe because of the rigid polyurethane foam insulation layer, which can prevent the infiltration of air and water.
              Putrefaction. At the same time, its foam cells are closed, water absorption is very small. High density polyethylene (HDPE) and glass fiber reinforced plastic (FRP) shells have good protection
              Corrosion, insulation and mechanical properties. Therefore, the outer skin of the working steel pipe is hard to be eroded by the outside air and water. As long as the water quality inside the pipeline is well treated
              According to foreign data, the service life of high-temperature prefabricated directly buried insulation pipe can reach more than 50 years, which is better than that of traditional trench laying and overhead laying
              The service life is 3 ~ 4 times longer.
              3、熱損耗低,節約能源。 熱損耗僅為傳統管材的25%
              3. Low heat loss and energy saving. The heat loss is only 25% of the traditional pipe material
              直埋保溫管 導熱系數 0.022kcal/m.h.℃ 憎水率 0.03kg/cm³
              The thermal conductivity of directly buried insulation pipe is 0.022kcal/m.h. ℃ and the hydrophobicity is 0.03kg/cm &amp; sup3;
              4 、占地少 施工快 有利于環境保護
              4. Less land occupation and faster construction is conducive to environmental protection
              Directly buried heating pipeline does not need to build a huge trench, only need to bury the insulation pipe underground, so it greatly reduces the land occupation and earthwork
              The excavation volume is more than 50%, and the amount of civil masonry and concrete is reduced by 90%. At the same time, the insulation pipe processing and field trenching are carried out in parallel
              The joint can shorten the construction period by more than 50%.
