Structural mechanism of corrosion insulation steel: 1, outer jacket pipe: groundwater protection insulation from price erosion 3PE anti-corrosion pipe insulation, duct work and support can withstand some external loads, pipe work guaranteed to work. 2, anti-corrosion layers: an outer steel to avoid corrosion protection of steel corrosion and prolong the service life of steel. 3, the drag reduction layers: steel work to ensure the free movement of expansion and contraction. 4, polyurethane foam layer: Polyurethane corrosion guarantee medium temperature pipe insulation manufacturers to ensure that the outer protective tube surface temperature maintained. 5, barrier, reflective layer: to ensure that organic foam material does not enter the high-temperature inorganic hard layer; reflective layer high-temperature part of the heat. 6, the working pipe: to ensure the normal flow of the transmission medium. 7, inorganic rigid insulation: temperature, to ensure that the interface between the temperature of the organic insulation layer of polyurethane anti-corrosion pipe insulation suppliers to ensure that the bubble will not be carbonized. Corrosion insulation corrosion pipe insulation layer structure: (1) buried steel pipeline corrosion insulation layer is made of corrosion layer - a protective layer consisting of a composite structure - insulation. Coating means hot melt adhesive layer anti-corrosion coatings or corrosion resistance; refers to the foam insulation layer; protective layer is the layer of polyethylene plastic. (2) coating material and thickness is determined by the design, but the thickness of not less than 80μm. (3) the use of economic insulation thickness should be calculated to determine the thickness, but not less than 25mm. (4) protective layer thickness should be determined according to the diameter and the construction process, but should not be less than 1.2 mm. (5) the end surface corrosion insulation layer must be sealed watertight with a waterproof cap. And thermal structure of laying oil and gas pipelines usually overhead, trenches and burying.
