What are the advantages and disadvantages of thermal insulation steel pipe? When we decide to choose thermal insulation steel pipe, which of the following aspects can we choose thermal insulation steel pipe? The following Borui pipeline tells you what are the advantages and disadvantages of insulation pipes, and how to choose?

What is an insulated steel pipe? It is a steel pipe that is processed by thermal insulation process to ensure that the temperature and surface temperature of the working steel pipe meet or meet the requirements of use under the action of different working environments and external media.

Cathodic protection of direct buried insulation pipes is an electrochemical protection method in the metal anti-corrosion process. Different from other direct buried insulation pipe anti-corrosion processes, he applies an electric current to the protected metal body, so that the electrode potential of the protected metal body shifts negatively, which is that the metal loses the trend of spontaneous change from atomic state to ionic attitude, so as to fundamentally start from the root. The occurrence of rotten candles is suppressed. However, this process must be carried out in an electrolyte, so buried steel pipes are very suitable for cathodic protection.

Cathodic protection and the anti-corrosion layer of the direct buried insulation irrigation pipe itself complement each other, the existence of the anti-corrosion layer can greatly reduce the current consumed by the cathodic protection, and the cathodic protection can make up for the lack of integrity of the anti-corrosion layer, so as to achieve a perfect combination in terms of safety and economy.

High temperature prefabricated direct buried insulation pipe is a kind of direct buried prefabricated insulation pipe with good thermal insulation performance, safety and reliability, and low engineering cost. It effectively solves the problems of heat preservation, sliding lubrication and waterproofing of exposed pipe ends of prefabricated direct buried insulation pipes for 130°C-600C high temperature heat transmission in urban central heating. High-temperature prefabricated direct buried insulation pipe not only has advanced technology and practical performance that are difficult to match in traditional trenches and overhead laying pipelines, but also has significant social and economic benefits, and is also a powerful measure for heating energy saving.

Because the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, it isolates the penetration of air and water, and can play a good anti-corrosion effect. At the same time, its foam cells are closed, and the water absorption is very small. High-density polyethylene shell and FRP shell have good anti-corrosion, insulation and mechanical properties. Therefore, the outer skin of the working steel pipe is difficult to be eroded by the outside air and water.

The moisture drain pipe on the steel casing can not only discharge moist gas in time, but also serve as an alarm signal tube for daily operation. The thermal compensation of the pipeline adopts high-quality bellows compensator, and it is installed in the casing to make a direct burial form, without setting up an observation well, which is convenient for construction operation and short construction period. Suitable for transporting 2.5MPa, 350 degrees Celsius below steam or other media, the product with steel pipe as the outer protective layer, with high strength, not easy to damage, easy construction maintenance, long service life advantages.The relevant decoration master said that when the decoration of the house, the selection of insulation materials is a very important link, which involves the quality of our life in the future.
