The black jacket directly buried straight steel pipe is a reliable solution to the strict waterproofing of the directly buried thermal insulation control manufacturer. Besides having good mechanical strength, the polyurethane foam insulation pipe steel sleeve is welded and connected, because the reliability of the high strength and waterproof sealing performance is very high.

　　In addition, the high temperature resistance of the steel sheathed steel buried insulation pipe can not be compared with other external protection pipes. In order to ensure the high underground water level and ensure that the underground water level does not affect the normal operation of the prefabricated directly buried thermal insulation steam pipeline in Tianjin, the outer protective layer of the steel jacketed steel steam thermal insulation pipeline is preferably a tight and solid steel pipe shell. Anti corrosion coating: extend the service life of steel pipe, protect the outer steel pipe from corrosion.

　　External insulation steel pipe: to ensure the normal operation of the directly buried insulation pipe, the manufacturer of the directly buried insulation pipe protects the insulation layer from groundwater erosion, supports the working pipe and can bear certain external load.

　　Polyurethane foam layer: the role of polyurethane foam insulation tube is to ensure that the medium temperature and the surface of the outer tube remain at room temperature. Tianjin prefabricated direct buried insulation and reflective layer: steel jacket steel steam insulation pipe design, to ensure that organic foaming materials will not enter the inorganic hard high temperature layer.
