Abstract
The utility model relates to a high-temperature-resistant insulated thermal pipeline, providing an insulation layer outside a pipeline with high-temperature-resistance and long service life, which is characterized in that a high-temperature-resistant anticorrosive layer (2), a foam insulation layer withstand 150 degree (3) and a polyethylene protective layer (4) successively form on the external surface of a pipeline (1); the external surface of the pipeline is sand-blast treated and then is coated with high-temperature-resistant anti-corrosive coating and the thickness of the anti-corrosive coating is generally above 80um; due to that the anti-corrosive coating is firmly bonded with the steel pipe, when the outside protective layer is damaged in construction or due to other causes, the anticorrosive layer can prevent water from contacting and corroding the steel pipe surface; the insulation layer is high-temperature-resistant polyurethane foam with low water absorption, big density, high strength and good insulating effect; the outside protective layer can adopt a yellow jacket or a black jacket according to the underground requirement or the overhead requirement; the performances of polyethylene such as tensile strength, breaking elongation rate, and ultraviolet ray ageing resistance are better; the structure integrates anticorrosion performance and insulation performance and is the best product for the thermal pipeline to convey fluid.
Description
(1) technical field:
The utility model relates to the high-temperature-resistant thermal-insulation heat distribution pipeline of conveyance fluid.
(2) background technique:
The conveying of all fluids all will be carried with pipeline in water in life, production and the heating, generally all is the metallic steel pipeline.Mode of execution has two kinds: a kind of is built on stilts or on the ground, year in and year out through wind and weather and oxidation, some pipeline generation rust corrosions also will be bored a hole for a long time afterwards.Another kind is to be embedded in undergroundly, helps surface construction and insulation, but also can rust corrosion after long-term, shortens the pipeline spreadable life.Bring influence and stopping production then can for life and production if generation is bored a hole, the while is befouling environment again, makes troubles to maintenance.It relates to the Important Project of decades the laying of pipeline, avoid corrosion, is located in ice box and also will considers insulation, any problem do not occur after long-term the use.
(3) model utility content:
Technical problem to be solved in the utility model is at the problem that exists in the background technique, and long high-temperature-resistant thermal-insulation heat distribution pipeline of a kind of life-span is provided.
The invention for solving the technical problem can reach by following technical solution: form the high-temperature resistant anti-corrosive layer in regular turn at pipeline external surface, heatproof reaches 150 ℃ polyurethane foam insulation layer and polythene PE protective layer.
Because pipeline external surface is after sand blast; the coating high heat resistant corrosion-proof paint is generally more than the 80 μ m, and anticorrosive paint and iron and steel pipe bonding are firmly; when external protection was caused breakage by damaged or other reason in construction, anticorrosive coat can stop water to contact with steel tube surface to cause corrosion.Thermal insulation layer is high temperature resistant polyurethane foam, and water absorption rate is low, and density is big, intensity height, high insulating effect; External protection can adopt yellow jacket or black jacket according to the requirement of burying ground or make somebody a mere figurehead; performances such as poly tensile strength, elongation at break, ultraviolet-resistant aging are all relatively good; this structure integrates the corrosion-resistant thermal insulation performance, is the best product of heat distribution pipeline conveyance fluid.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: apply heat-resistant coating outward, do anticorrosive coat; Thermal insulation layer adopts heatproof to reach 150 ℃ polyurethane foam material, adds no fluorine catalyst and various small powder, and the formation capacity is 60～120kg/m
3Rigid foam, compressive strength is greater than 0.6MPa; External protection adopts HXJ modified poly ethylene pellet, adds yellow (deceiving) dyestuff as required, forms yellow (deceiving) jacket protective layer, anti-ultraviolet aging.Product specification is from Φ 48mm～Φ 1020mm, and the thickness of thermal insulation layer is more than the 25mm, and the thickness of protective layer is 1.5mm-14mm.Outer surface of steel tube adopts derusting by sandblasting, and thermal insulation layer adopts polyurethane high pressure painting technology, good product quality, manufacturing efficiency height.
(4) description of drawings:
Accompanying drawing is the utility model sectional structure chart.
(5) embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
Shown in accompanying drawing, form high-temperature resistant anti-corrosive layer 2 in regular turn at pipeline 1 outer surface, heatproof reaches 150 ℃ polyurethane foam insulation layer 3 and polythene PE protective layer 4.
Adopt such scheme, pipeline external surface is after sand blast, and the coating high heat resistant corrosion-proof paint is as coating such as H88, H87 liquid epoxy coating and D518 heat-resistance type epoxies; Be generally more than the 80 μ m, anticorrosive paint and iron and steel pipe bonding firmly, when external protection was caused breakage by damaged or other reason in construction, anticorrosive coat can stop water to contact with steel tube surface to cause corrosion.Thermal insulation layer is high temperature resistant polyurethane foam, and water absorption rate is low, and density is big, intensity height, high insulating effect; External protection can adopt yellow jacket or black jacket according to the requirement of burying ground or make somebody a mere figurehead; performances such as poly tensile strength, elongation at break, ultraviolet-resistant aging are all relatively good; this structure integrates the corrosion-resistant thermal insulation performance, is the best product of heat distribution pipeline conveyance fluid.
