Heating steel sleeve, steel insulation pipe, high-temperature buried insulation pipe, Xingsong pipeline processing customization

Description :

　　Steel sheathed steel insulation pipe, also known as "pipe in pipe", is composed of high-density polyethylene outer protective layer, polyurethane rigid foam plastic pipe and steel pipe. One is composed of steel pipes for conveying medium, anti-corrosion outer steel pipes, and ultra-fine glass wool filled between steel pipes and outer steel pipes, or graphite, calcium silicate tile shell and polyurethane foam filled composite. The steel casing (steel sleeve steel) burial technology is a new burial technology that is waterproof, leak proof, anti-seepage, pressure resistant, and fully enclosed. It is a major breakthrough in the use of direct burial laying technology in areas with high groundwater levels. The steel sleeve steel insulation pipe has the characteristics of tight and reliable waterproofing. In addition, it needs to have good mechanical strength. Due to its high strength, the steel sleeve is connected by welding, and its waterproof sealing performance is very reliable. In addition, its high temperature resistance is unmatched by other external protective pipes.

　　Structural mechanism of internal sliding steel sleeve steam insulation pipeline:

　　1. Working steel pipe: Ensure the normal flow of the conveying medium.

　　2. Anti corrosion coating for working pipes: to prevent the working steel pipes from being corroded by corrosive substances and extend their service life.

　　3. Drag reduction layer: Ensure the free movement of the working steel pipe during thermal expansion and contraction.

　　4. Inorganic hard insulation layer: resistant to high temperature, ensure the interface temperature between organic insulation layer and polyurethane foam, and prevent carbonization.

　　5. Reflective layer: ensure that the organic foam material will not enter the inorganic hard high-temperature insulation layer; Reflect some heat from the high-temperature resistant insulation layer.

　　6. Polyurethane foam layer: ensure the medium temperature, and ensure the surface of the outer steel pipe to maintain normal temperature.

　　7. Coat steel pipe: protects the insulation layer from groundwater erosion, supports the working pipe and can withstand certain external loads, ensuring the normal operation of the working pipe.

　　8. Coat steel pipe anti-corrosion layer: protects the coat steel pipe from corrosion by corrosive substances and extends the service life of the steel pipe.
