Set outside steel pipe it is uniform in heat-insulation layer, heat-insulation layer be fixed with the annulus that heat-insulating heat-preserving material is made, two adjacent annulus it
Between space be vacuum, be cased with outside heat-insulation layer being brushed with one layer of corrosion resistant coating outside outer protection tube, outer protection tube, solve insulating steel tube sanction
The problem of heat insulation effect being influenceed after cutting.
But, in prior art and Patent No. CN201120160833 patent, by setting heat-insulation layer, it will be incubated
The outer protection tube that the outer suit of layer is brushed with one layer of corrosion resistant coating carries out corrosion-resistant thermal insulation to steel pipe, still, is not carried out for steel duct
Protection improve, and if there is crack in the vacuum structure between its annulus of heat-insulation layer two, can not be further continued for insulation.
Utility model content
The purpose of this utility model is to solve the above problems, devise a kind of polyurethane heat-insulation steel pipe.
Realize that above-mentioned purpose the technical solution of the utility model is, a kind of polyurethane heat-insulation steel pipe, including steel pipe body, institute
State steel pipe body outer surface and be coated with epoxy powder anti-corrosion coating, the epoxy powder anti-corrosion coating outer surface is coated with adhesive
Layer, the gluing oxidant layer outer surface is coated with polyethylene anticorrosion coating, the steel pipe body inwall adhesive insulating layer, the insulation
The material of layer is polyurethane.
The epoxy powder anti-corrosion coating layer thickness>100um.
The adhesive layer thickness is 170-250um.
The polyethylene anticorrosion coating layer thickness is 2.5-3.7mm.
The insulation layer thickness is 20 millimeters -200 millimeters.
A kind of polyurethane heat-insulation steel pipe made using the technical solution of the utility model, the present apparatus uses polyurethane conduct
Heat-insulation layer, polyurethane has that light weight, thermal conductivity factor are low, heat-resist, ageing-resistant, easy cohere, burn not with other base materials
The excellent properties such as molten drop are produced, meanwhile, polyurethane has preferable elasticity, and when receiving media impingement, polyurethane is in outer masterpiece
Compression is criticized with lower, after external force disappears, polyurethane restores to the original state again, while there is excellent wear-resisting, acidproof, alkaline-resisting, good antiscale property,
Radiation hardness, hydrolysis aging, high resiliency, the combination property of resistance to mechanical impact, the polyethylene of the three-decker of outer wall of steel pipe spraying
I.e. 3PE corrosion-inhibiting coatings have good corrosion resistance, water resistant permeability to gas and mechanical property etc., and three pe corrosion-inhibiting coatings are combined
The high permeability resistant of epoxy resin and polythene material, up to the present it is the generally acknowledged use effect in the whole world the features such as mechanical performance is high
The optimal anticorrosion coating on pipeline of really best, performance, extends the service life of steel pipe.
