Facing foam insulation tubes

Buried pipe insulation foam coating process 1: protective outer steel to avoid corrosion corrosion steel pipe, pipe prolong life. 2. The outer jacket pipe: groundwater protection insulation from erosion, supporting the work of the tube and can withstand external loads, to ensure normal operation of the working tube. 3. The polyurethane foam layer: to ensure that the medium temperature to ensure that the outer surface of the protective tube maintained at room temperature. The barrier, reflective layer: to ensure that organic foam material does not enter the hard inorganic refractory layer; a reflective layer portion of high temperature heat. 5. inorganic rigid insulation: high temperature, to ensure the interface between temperature and the organic insulating layer, to ensure not to be carbonized foam. 6. drag layer: to ensure the free movement of expansion and contraction pipe work. 7. Working pipe: to ensure the normal flow of the transmission medium. Steel jacket pipe insulation Overview: the transmission medium steel, corrosion and superfine wool coat steel pipe and the jacket pipe is filled between the combination, but also can be graphite, calcium silicon tile shell filled with polyurethane foam and composite made . Steel casing (steel jacket) embedded technology is a waterproof, leakproof laying of new technologies, impermeability, compression and fully enclosed, is a major breakthrough Buried technology used in high water table areas. The primary issue of the protection tube buried pipe is tight waterproof reliability, in addition to have good mechanical strength, high strength steel casing due to the use of welded connections, waterproof sealing performance reliability is very high, in addition, its high temperature performance is Other outer protective tube can not be compared. In areas of high water table, in order to ensure the normal operation of the steam does not affect groundwater buried pipe, the outer protective layer is preferably made of sturdy, sealed steel casing. Buried steel jacket pipe insulation structure according to a sliding manner divided into: internal sliding outer sliding two. 1, sliding type: insulation from the pipe work, silicate, drag reduction layer, porous calcium silicate, insulation, stainless steel fastening strip, aluminum foil reflective layer of polyurethane insulation, jacket pipe, the outer coating components. 2, the outer sliding: the working pipe insulation, glass wool insulation layer, a reflective layer of aluminum foil, stainless steel fastening tape, slide guide bracket, the air insulation layer, the outer protective pipe, the outer coating composition. Mechanisms of buried steel pipe insulation steel jacket 1. coating: protective outer steel to avoid corrosion corrosion steel pipe, pipe prolong life. 2. The outer jacket pipe: groundwater protection insulation from erosion, supporting the work of the tube and can withstand external loads, to ensure normal operation of the working tube. 3. The polyurethane foam layer: to ensure that the medium temperature to ensure that the outer surface of the protective tube maintained at room temperature. The barrier, reflective layer: to ensure that organic foam material does not enter the hard inorganic refractory layer; a reflective layer portion of high temperature heat. 5. inorganic rigid insulation: high temperature, to ensure the interface between temperature and the organic insulating layer, to ensure not to be carbonized foam. 6. drag layer: to ensure the free movement of expansion and contraction pipe work. 7. Working pipe: to ensure the normal flow of the transmission medium.
