Since the insulation tightly bonded polyurethane rigid foam insulation layer steel jacket pipe insulation, cut off from air and water infiltration, can play a good anti-corrosion effect. While its foaming holes are closed, water absorption is small. High density polyethylene shell, fiberglass shell have good anti-corrosion, insulation and mechanical properties. Therefore, it works hard to be outside steel jacket of air and water erosion. As long as internal quality pipeline deal, according to foreign materials, the service life of high temperature prefabricated buried pipe insulation up to 50 years, than the traditional trench laying, overhead laying three to four times higher service life. Steel jacket is much lower than other steam pipe insulation pipe insulation material used in the past, the insulation effect increased by 4 to 9 times. Further water absorption is very low, about 0.2kg / m2. The reason is due to low water absorption rate of closed-cell polyurethane foam about 92%. Low thermal conductivity and low water absorption prefabricated pipe insulation, plus the insulation and a waterproof good performance of high-density polyethylene or fiberglass protective shell, has changed the traditional trench laying heating pipes status "wearing wet jacket," the steel jacket pipe insulation , greatly reducing the overall heat loss of the heating pipes, heating network heat loss is 2%, less than 10% of international standards. Corrosion, good insulation properties, long service life.
