The difference between polyurethane direct-buried insulating pipe and traditional insulating pipe
There are two general explanations for the purpose of polyurethane directly buried insulating pipes.
One is to ensure that the pipeline can operate temporarily in underground fluctuations.
Second, to ensure that the insulation pipe can play a good thermal insulation effect, do not waste power, do not destroy garden greening.
With the improvement of society and the development of science and technology, various kinds of jacket insulation pipes come out indirectly, and the variety of products is more and more different. Buried polyurethane direct-buried insulation pipe has good thermal insulation function, and its heat loss is only 25% of the traditional pipe material. Temporary operation can waste a small amount of power and obviously reduce the power cost. The utility model has the advantages of simple construction, obvious energy saving and anticorrosion effect, and is used in a small amount for heat preservation of various industrial pipes such as heating, refrigeration, oil transportation, chemical industry, etc.
The first aspect is the structure and function of insulation pipe. The polyurethane prefabricated insulation pipe is constructed with internal maintenance layer, thermal insulation layer and external maintenance layer from inside to outside. The inner maintenance layer is a steel pipe with delivery medium, which has good corrosion resistance and waterproof function. The rigid polyurethane foam insulation layer between the steel tube and the outer maintenance layer is made up of three pipes by foam tube technology. The outer maintenance layer is the high density polyethylene outer casing. Generally speaking, the thermal insulation function of polyurethane prefabricated insulating pipes is better than that of traditional insulating pipes, and the effect of thermal insulation and cooling is better.
The second aspect is industrial consumption. Polyurethane prefabricated insulating pipes are customized afterwards. It is more conducive to the practical consumption of insulating pipes. It has great sensitivity and compliance. It can design directly buried insulating pipes with different parameters according to different needs.
The third aspect is from the laying way. Traditional heat preservation pipes are laid by trench and overhead, which have high cost and long construction time. However, polyurethane prefabricated insulation pipes are laid directly, which occupies less land, is simple and fast to construct, and is conducive to the maintenance of the environment.
The polyurethane foam insulation pipe is tightly adhered to the outer skin of the steel pipe because of the rigid polyurethane foam insulation layer, which can isolate the infiltration of air and water, and can play a good anti-corrosive effect. At the same time, its foaming holes are closed, water absorption is very small, high polyethylene shell, FRP shell has good anti-corrosion, insulation and mechanical functions.
