Abstract
The utility model discloses a kind of anti-corrosion heat insulation pipe, comprises body, is fixed with thermal insulation layer, protective coating and anticorrosive coat at described tube wall; Described protective coating is between thermal insulation layer and anticorrosive coat; Described thermal insulation layer adopts asphalt-base polyurethane foam; Described protective coating comprises polyethylene layer and nonwoven layer.Asphalt-base polyurethane foam layer of the present utility model has heat-insulating property, impermeability, resistance to chemical attack, ageing-resistant performance, and protective coating has good mechanical strength, the stress cracking performance of resistance to environmental aging and distinctive plastic elongation, and there is good waterproof, compressive strength, anti-ultraviolet property, forever can use in the sun, thus improve the working life of pipeline.
Description
Technical field
The utility model relates to a kind of pipeline, particularly relates to a kind of anti-corrosion heat insulation pipe.
Background technique
Northern China most area, when the pipeline such as crude oil, heating employing surface variant laying and station field pipeline network construction, all needs to take anticorrosion and Insulation.General ground anti-corrosion heat insulation pipe anticorrosive coat adopts coating to brush, and thermal insulation layer adopts rock wool or the fibre pipe such as silicate, alumina silicate shell product, also needs galvanized wire to carry out colligation, and protective layer adopts galvanized sheet iron and reinforces with rivet.Above-mentioned processing mode compressive strength is low, anti-aging and water-proof performance is poor, and product comprehensive quality can not get ensureing, in addition, because oil field geographical conditions are complicated, particularly soil alkalinity is large, be easy to make pipeline outer wall corrode and cause insulation failure, affect pipeline allomeric function and working life.
Model utility content
The utility model is intended to overcome the deficiencies in the prior art part and provide a kind of mechanical strength high, anti-aging and water-proof performance good, the anti-corrosion heat insulation pipe of long service life.
The technical solution of the utility model is: a kind of anti-corrosion heat insulation pipe, comprises body, is fixed with thermal insulation layer, protective coating and anticorrosive coat at described tube wall; Described protective coating is between thermal insulation layer and anticorrosive coat; Described thermal insulation layer adopts asphalt-base polyurethane foam; Described protective coating comprises polyethylene layer and nonwoven layer.
Preferably, the thickness of described polyethylene layer is 1.5mm-2.0mm.
The beneficial effects of the utility model: asphalt-base polyurethane foam layer of the present utility model has heat-insulating property, impermeability, resistance to chemical attack, ageing-resistant performance, and protective coating has good mechanical strength, the stress cracking performance of resistance to environmental aging and distinctive plastic elongation, and there is good waterproof, compressive strength, anti-ultraviolet property, forever can use in the sun, thus improve the working life of pipeline.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of the utility model anti-corrosion heat insulation pipe;
In figure: 1 body, 2 thermal insulation layers, 3 protective coatings, 4 anticorrosive coats.
Embodiment
By reference to the accompanying drawings the mode of execution that the utility model provides is described in further detail:
As shown in Figure 1, a kind of anti-corrosion heat insulation pipe, comprises body 1, is fixed with thermal insulation layer 2, protective coating 3 and anticorrosive coat 4 at described body 1 outer wall; Described protective coating 3 is between thermal insulation layer 2 and anticorrosive coat 4; Described thermal insulation layer 2 adopts asphalt-base polyurethane foam; Described protective coating 3 comprises polyethylene layer and nonwoven layer.
Preferably, the thickness of described polyethylene layer is 1.5mm-2.0mm.
Asphalt-base polyurethane foam layer of the present utility model has heat-insulating property, impermeability, resistance to chemical attack, ageing-resistant performance, and protective coating has good mechanical strength, the stress cracking performance of resistance to environmental aging and distinctive plastic elongation, and there is good waterproof, compressive strength, anti-ultraviolet property, forever can use in the sun, thus improve the working life of pipeline.
In this description, the utility model is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
