Energy saving products have low heat loss
The thermal conductivity of prefabricated polyurethane buried insulation pipes is λ=0.0130.03kcal/m · h · oC, which is much lower than other commonly used pipeline insulation materials in the past. Its insulation effect is improved by 4-9 times. 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%.
The product is corrosion-resistant, has good insulation performance, and has a long service life.
As the polyurethane rigid foam insulation layer is closely bonded to the steel pipe skin, the directly buried insulation pipe can isolate the infiltration of air and water and play a good anti-corrosion role. And its foam pores are all closed, with very low water absorption. High density polyethylene shell (or fiberglass shell) has 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 well treated, according to foreign data, the service life of prefabricated polyurethane buried insulation pipes can reach more than 50 years, which is 3-4 times longer than traditional trench laying and overhead laying.
Dongying steam insulation pipeline, steel sleeve steel insulation pipeline, Shandong insulation pipe manufacturerLess land occupation, faster construction, beneficial for environmental protection and reducing construction disturbance to residents.
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 greatly shorten the construction period. Due to the reduction in transportation of bricks, cement, sand and gravel, and surplus soil, the emissions of vehicle exhaust, dust, and noise during the construction process have been reduced, thereby protecting the environment.
Seat belt warning system
Prefabricated polyurethane buried insulation pipes can be equipped with leakage alarm lines according to customer requirements. 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 network. Now we can also independently produce buried insulation pipes with warning lines, filling the gap of the previous lack of warning systems.
