Steel jacketed steel insulation steel pipe

Speaking of double-layer protection, we should talk about the structure of steel-insulated steel pipes with steel sleeves. Manager Wang
The corrosion layer protects the outer steel pipe to prevent corrosives from corroding the steel pipe and prolongs the service life of the steel pipe.
The protective 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.
The urethane foam layer ensures the medium temperature and ensures that the surface of the outer protective tube remains at normal temperature.
The reflective layer ensures that the organic foam material does not enter the inorganic hard high-temperature-resistant layer and reflect part of the heat from the high-temperature-resistant layer.
The mechanical hard insulation layer is resistant to high temperatures, ensuring the interface temperature with the organic insulation layer and ensuring that the foam is not carbonized.
The resistance layer ensures that the working steel pipe can move freely when it expands due to thermal expansion or contraction.
Making steel pipes ensures the normal flow of the conveying medium.
