Characteristics of polyurethane foam insulation pipe products
1. Reduce project costs.
According to relevant departments' calculations, double pipe heating pipelines can generally reduce project costs by about 25% (using fiberglass as a protective layer) and 10% (using high-density polyethylene as a protective layer).
2. Low heat loss, saving energy.
Its thermal conductivity is λ=0.0130.03kcal/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%, which is less than the standard requirement of 10%.
3. Anti corrosion, good insulation performance, and long service life.
As the polyurethane rigid foam insulation layer is closely bonded to the outer skin of the steel pipe, 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.
4. Shandong direct buried insulation pipe price, Dongying insulation pipe manufacturer, manufacturer direct supplyLess land occupation, faster construction, and favorable environmental protection.
Directly buried heating pipelines do not require the construction of large trenches, only the insulation pipes need to be buried underground, thus greatly reducing project land occupation, reducing excavation volume by more than 50%, and reducing civil engineering masonry and concrete volume by 90%. At the same time, the processing of insulation pipes and on-site trenching are carried out in parallel, and only on-site joints are required, which can shorten the construction period by more than 50%.
5. Safety.
There is a leakage alarm line. Once a leakage occurs in a certain part of the pipeline, the accurate location and degree of leakage of the insulation pipeline can be displayed on the detection instrument through the transmission of the alarm line, so as to notify the leakage personnel to quickly deal with the leaking pipe section and ensure the safe operation of the heating pipeline network. At present, domestically produced insulation pipes are not equipped with leakage alarm lines, and this gap needs to be filled.
