Description :
Characteristics of polyurethane insulated steel pipe:
1. According to relevant departments' calculations, polyurethane insulated steel pipes can generally reduce project costs by about 25% (using fiberglass as the protective layer) and 10% (using high-density polyethylene as the protective layer)
2. Low heat loss and energy-saving. The thermal conductivity of polyurethane is λ=0.013-0.03kca/m · h · oC, which is much lower than other commonly used pipeline insulation materials in the past, and the insulation effect is improved by 4-9 times. Moreover, its water absorption rate is very low, about 0.2kg/m2. The reason for low water absorption is that the closed cell rate of polyurethane foam is up to 92%. Low thermal conductivity and low water absorption, combined with insulation layer and high-density polyethylene or fiberglass protective shell with good waterproof performance, have changed the traditional situation of "wet cotton jacket" for laying heating pipes in underground trenches, greatly reducing the overall heat loss of heating pipes. The heat loss of the heating network is 2%, far less than the international standard requirement of 10%.
3. It has good corrosion resistance, insulation performance and long service life. As the polyurethane rigid foam insulation layer is tightly bonded to the steel pipe skin, it can isolate the infiltration of air and water and play a good anti-corrosion role. At the same time, its foam pores are all closed, and its water absorption is very low. The high-density polyethylene shell and fiberglass shell both have good anti-corrosion, insulation, and mechanical properties. Therefore, the outer skin of the working steel pipe is difficult to be eroded by external air and water. As long as the water quality inside the pipeline is treated well, according to foreign data, the service life can reach more than 50 years, which is 3-4 times longer than the service life of traditional trench laying and overhead laying.
