Abstract
The utility model relates to an anticorrosive and heat-insulating glass fiber foam thermal pipeline for the transmission of fluids, comprising a temperature resistant epoxy resin coating painted on the external surface of a pipeline (1) as an anticorrosive coating (2), a polyurethane foam heat insulation layer (3) capable of resisting a temperature as high as 150 DEG C, and a glass fiber reinforced plastic pipe protective layer (4). The utility model is a steel pipeline for hot fluids transmission, which is characterized in that after being sandblasted, the external surface is painted with a layer of high-temperature resistant and anticorrosive coating usually thicker than 80 um; due to the firm adhesion between the anticorrosive layer and the steel pipeline, the contact of media such as water with the surface of the steel pipeline is prevented when the protective layer is destroyed in construction or due to other reasons, therefore, corrosion is avoided; the heat insulation layer is a layer of high temperature resistant polyurethane foam of low water absorption rate, great density, high strength and good heat insulating effect; glass fiber reinforced plastic and reinforce resin material is adopted for the protective layer, which has good impact resistant property, anti-moisture and chemical corrosion resistant properties, high intensity, anti ultraviolet ray and aging-bearing properties. The utility model has an advantage of combination of the anticorrosive property and the heat-insulating property, therefore, the utility model is the best product of thermal pipelines for hot liquids transmission.
Description
(1) technical field:
The utility model relates to a kind of glass fiber reinforced plastic foam corrosion-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 a kind of resistant to elevated temperatures glass fiber reinforced plastic foam corrosion-resistant thermal insulation heat distribution pipeline is provided.
The invention for solving the technical problem can reach by following technical solution: apply outside pipeline that the heatproof epoxy resin coating is made anticorrosive coat, heatproof reaches 150 ℃ polyurethane foam insulation layer and Glass Steel Tube protective layer.
Because applying heat-resistant coating outside steel pipe does anticorrosive coat; Thermal insulation layer adopts heatproof to reach 150 ℃ polyurethane foam material, adds no fluorine catalyst and various small powder, and formation unit weight is 60～80kg/m
3Rigid foam, compressive strength is greater than 0.6MPa; External protection adopts the Glass Steel Tube of compressive strength height, ultraviolet-resistant aging.Product specification is from Φ 426mm～Φ 1020mm, and the thickness of thermal insulation layer is more than the 40mm, and the thickness of protective layer is 5～14mm.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.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: serviceability temperature of the present utility model is-40 ℃～150 ℃; Outer wall of steel pipe adopts anticorrosive paint, combines tightly with steel pipe and thermal insulation layer, effectively prevents the outer wall of steel pipe corrosion, life-saving, and antiseptic property is good; Polyurethane foam adopts floride-free technology, and is pollution-free to atmosphere, compliance with environmental protection requirements.The compressive strength height, capacity 60～80kg/m
3, compressive strength is greater than 0.6MPa; External protection adopts glass fibre reinforced plastics to strengthen resin material, the intensity height, and antiseptic property is good, and impact resistance is good, and moisture resistance is wet, ultraviolet-resistant aging.
(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, coating heatproof epoxy resin coating is made anticorrosive coat 2 outside pipeline 1, heatproof reaches 150 ℃ polyurethane foam insulation layer 3 and Glass Steel Tube protective layer 4.
Above-mentioned glass foam corrosion-resistant thermal insulation heat distribution pipeline is used on the hot pipe network engineering, the steel pipe of the utility model for carrying hot fluid to use, outer surface is after sand blast, and the coating high heat resistant corrosion-proof paint is as coating such as H87, H88 liquid epoxy coating and D518 heat-resistance type epoxies; Thickness is generally more than the 80 μ m, anticorrosive coat and steel pipe bonding firmly, when external protection damaged or other reason in construction causes when damaging, anticorrosive coat can stop medium such as 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, density is big, intensity is high, high insulating effect; External protection adopts glass fibre reinforced plastics to strengthen resin material, and this material has impact resistance preferably, moisture resistance can and resistance to chemical corrosion, intensity height, ultraviolet-resistant aging performance good.This structure integrates the corrosion-resistant thermal insulation performance, is the best product of heat distribution pipeline conveyance fluid.
