Steel bush embedding technology is a new technology, which is a breakthrough in the technology of steel bush laying. This technology is suitable for use in the areas with high underground water level.

1 It has waterproof, leak-proof, impermeability, compression and full closure of the technical advantages. Steel sleeve steel buried pipe insulation structure consists of three layers: the transmission medium of the steel pipe, from the role of corrosion and supporting the jacket steel pipe, and the transmission pipe and jacket pipe filled with ultra-fine glass wool composition, which can also be filled with graphite, Silicate tile shell or polyurethane foam.

2 steel sleeve steel steam direct buried prefabricated pipe insulation for conveying 2.6mpa, 360 degrees Celsius Jiashan bearing degrees below the steam or other high-temperature medium, because of its outer sheath composed of steel pipe, not only high strength, easy maintenance, easy to damage , And a longer service life.

3 to prevent the reliability of groundwater penetration problems underground buried pipe is the primary problem, in addition, the excellent mechanical strength is buried pipe can not be ignored. Because the outer supporting steel pipe is connected by welding, its sealing performance is very excellent, and the solidity of the outer sheath steel pipe ensures the normal operation of the steel bush steel buried pipe in the high groundwater level.

Uses: 4 steam insulation pipe is widely used in liquid, gas pipeline network, chemical pipeline insulation works, petroleum, chemical, central heating network, central air conditioning ducts, municipal works. Steel sleeve insulation pipe insulation structure according to different sliding mode is divided into: within the sliding and external sliding 1, the sliding type: insulation structure by the work of steel, aluminum silicate, drag reduction layer, calcium silicate, insulation , Stainless steel fastening strip, aluminum foil reflective layer, polyurethane insulation layer, jacket steel pipe, outer coating composition. 2, outside the slide: insulation structure by the work of steel, glass wool insulation layer, aluminum foil reflective layer, stainless steel fastening belt, sliding guide bracket, air insulation layer, outer protective steel pipe, outer coating composition. 1. Anticorrosive layer: protect the outer steel pipe to avoid corrosive corrosion of steel pipe, to extend the service life of steel pipe. 2. Protection of steel pipe: to protect the insulation layer from groundwater erosion, supporting the work of the tube and can withstand a certain external load to ensure that the work of the normal work. 3. Polyurethane foam layer: to ensure that the medium temperature to ensure that the outer surface of the protective tube to keep room temperature. 4. Barrier, reflective layer: to ensure that the organic foam material does not enter the inorganic hard high temperature layer; reflective part of the heat-resistant layer of heat. 5.Inorganic hard insulation: high temperature, to ensure that the interface between the organic insulation layer temperature, to ensure that the foam is not carbonized. 6. Drag reduction layer: to ensure that the work of thermal expansion and contraction of steel pipe free movement. 7. Working steel pipe: to ensure the normal flow of transmission medium.
