Abstract
The utility model discloses a prefabricated thermal insulating pipe made of composite materials, which is composed of a steel pipe, a polyethylene foam thermal insulation layer, a thermal-proof irradiation isolation layer, a polyurethane foaming thermal insulating layer, a PE casing or a reinforced fibreglass protection casing, wherein the outer round wall of the steel pipe is reinforced with a polyethylene foam thermal insulating layer; the outer round wall of the polyethylene foam thermal insulating layer is reinforced with the heatproof irradiation isolation layer; the outer wall of the thermal-proof irradiation isolation layer is reinforced with the polyethylene foam thermal insulating layer of which the outer round wall is reinforced with a polyurethane foaming thermal insulating layer. At last, the outer round wall of the polyurethane foaming thermal insulating layer is reinforced with the PE casing or the reinforced fibreglass protection casing. The utility model uses a thermal insulating pipe of the PE casing or the reinforced fiberglass protection casing. Besides, the thermal insulating pipe uses various materials and the arrangement of multi-ply thermal preservation and thermal insulation. The utility model has the advantages of high anti-pressing strength, strong anti-corrosion ability, good thermal insulating effect and convenient application.
Description
Affiliated technical field
It is heat preservation pipe prefabricated that the utility model relates to the high low temperature of a kind of composite material, specifically a kind ofly utilizes multiple material, and a kind of thermal insulation pipe with the heat insulation setting of multi-layer heat preserving is made belongs to the thermal insulation pipe technical field.
Background technique
At present, known heat distribution pipeline thermal insulation pipe, its structure mostly is by steel pipe and the outer thermal insulation layer that is provided with of steel pipe, coating constitutes, because thermal insulation layer adopts the coating of the glass fibre cloth that speckles with resin or paint to wrap up, not only intensity is low to make heat distribution pipeline, make it be difficult to resist the pressure of external load and cause unnecessary damage, in use need often overhaul or change thermal insulating material, cause the waste of human and material resources, fund, very unsatisfactory.
Summary of the invention
In order to overcome above-mentioned deficiency; the utility model provides the high low temperature of a kind of composite material heat preservation pipe prefabricated; it is a kind of multiple material that utilizes; a kind of thermal insulation pipe made from the heat insulation setting of multi-layer heat preserving; its compressive strength height, antiseptic power is strong, can protect the temperature of heating power pipe; can prevent the thermal radiation in the heating power pipe again, heat insulation effect is good.
The technological scheme that its technical problem that solves the utility model adopts is: reinforce the layer of polyethylene insulated foam coating on steel pipe cylindrical wall; on the cylindrical wall of this layer, reinforce one deck thermal radiation resistant separation layer again; on the cylindrical wall of thermal radiation resistant separation layer, add the layer of polyethylene insulated foam coating again; on the cylindrical wall of this layer, reinforce one deck polyurethane foam thermal-protective coating again, on the cylindrical wall of polyurethane foam thermal-protective coating, make one deck glass fibre reinforced plastics protection housing or PE frame at last with mechanical winding process or artisan craftsmanship.
The beneficial effects of the utility model are: adopt multiple material; the thermal insulation pipe that heat insulation setting of multi-layer heat preserving and glass fibre reinforced plastics casing body or PE frame are made; the compressive strength height; antiseptic power is strong; both can protect the temperature of heating power pipe, and can prevent the thermal radiation in the heating power pipe again, heat insulation effect is good; Applicable scope is extensive, and it is convenient to use.
