Steel-clad steel insulated seamless steel pipes can be used in various areas of people's lives and have a wide range of applications. They are also used in enterprise heat sources, power plant steam transportation, factory steam pipelines, etc.
Composition of steel-sheathed steel insulation seamless pipe:
1. Anti-corrosion layer: Protects the outer steel pipe from corrosive substances, which can extend the service life of the steel pipe.
2. Outer protection steel pipe: protect the insulation layer from groundwater erosion and ensure the normal operation of the working pipeline.
3. Glass wool insulation layer and air insulation layer: ensure that the surface of the outer protection tube maintains normal temperature.
4. Aluminum foil reflective layer: reflects part of the heat from the high temperature resistant layer to ensure that organic foam materials do not enter the inorganic hard high temperature resistant layer.
5. Inorganic hard insulation layer: ensure the interface temperature with the organic insulation layer and ensure that the foam is not carbonized.
6. The stainless steel fastening belt and sliding guide bracket ensure that the thermal expansion and contraction movement of the working steel pipe is not restricted.
7. Working steel pipe: It can ensure the normal flow of the conveying medium.
Advantages and characteristics of steel jacketed steel insulation pipe:
1. Good thermal insulation performance, heat loss is only 25% of traditional pipes.
2. It has strong waterproof and corrosion resistance and does not require additional trenches. It can be directly buried underground or in water. The construction is simple and fast, and the overall cost is low.
3. It can be directly buried in underground frozen soil because it also has good corrosion resistance and impact resistance at low temperatures.
4. The service life can reach 30-50 years. Correct installation and use can make the maintenance cost of the pipe network very low.
5. Insulated steel pipes with steel sleeves are suitable for heat and cold insulation projects that transport various media within the range of -50-150.
6. It occupies less space, has fast construction speed, and is conducive to environmental protection.
Industrial production capacity requirements for steel-cased steel steam insulation steel pipes:
Integrated insulation pipe: The three parts of steel pipe, insulation material and shell are firmly combined to form an overall structure. The biggest difference between these two protective layers is that one is wrapped glass cloth and the other is wrapped yarn. For steel-sheathed steel insulation structures, the use of internal fixed structures has great advantages.
As the operating boundaries of insulated steel pipes continue to expand, the sales of polyurethane insulated steel pipes have also increased significantly. This has caused some suppliers in the mall to use inferior steel pipe raw materials for production and sales to obtain benefits, but the rights and interests of consumers are not protected. This strong customer purchases polyurethane insulated steel pipes and goes to regular manufacturers for on-site acceptance and product investigation to ensure that their own interests are not harmed.
What is the effect of prefabricated polyurethane direct buried insulation pipe insulation material?
The thermal conductivity of prefabricated polyurethane direct-buried insulation pipes is λ=0.013-00 3kcal/m·h·OC, which is much lower than that of commonly used insulation materials in the past, and the thermal insulation effect is 4 times that of commonly used insulation materials in the past. According to the different outer protection tubes, it can be divided into steel sleeve structure and ladle steel combined structure. Prefabricated polyurethane directly buried insulated pipes can play a good anti-corrosion role because the polyurethane rigid foam insulation layer is closely combined with the outer layer of the steel pipe, which isolates the penetration of air and water
