Thermal insulation steel pipe foam has mechanical

The insulated steel pipe foam has mechanical and thermal insulation functions, and can withstand the temperature of 120 under normal conditions. After correction or combining with other insulation data, it can withstand the temperature and insulated steel pipe. Anti corrosion coating: Maintain the outer steel pipe to prevent corrosive substances from corroding the steel pipe, and extend the service life of the steel pipe. External steel pipe: maintains the insulation layer from groundwater corrosion, supports the work pipe, and can withstand certain external loads to ensure the normal operation of the work pipe. Polyurethane foam layer: it ensures the temperature of the medium and the external adhesion of the external maintenance pipe at normal temperature. Insulation and reflective layer: ensure that the organic foam data will not enter the inorganic hard high-temperature resistant layer; Reflect and resist some heat from the high-temperature layer. Inorganic hard insulation layer: resist high temperature, ensure the interface temperature with the organic insulation layer, ensure that the foam is not carbonized drag reduction layer: ensure that the operating steel pipe expands when heated and moves freely when cold shrinks.
