Abstract
The present invention relates to a heat insulating and energy saving technique for heating pipelines, which is characterized in that a high temperature resistant heat insulating layer, an anti-radiation layer, a heat preserving layer and an outer protective layer are orderly coated outside a conveying pipeline; the high temperature resistant heat insulating layer is an asbestos layer, the anti-radiation layer is made of composite aluminium foil, and the heat preserving layer is formed from heat preserving tiles made of composite silicate. Compared with the prior art, the present invention has the advantages of low heat loss in the conveying process of heating pipelines, particularly oil pipelines, high conveyance capability, and low production cost of crude oil.
Description
Technical field
The present invention relates to a kind of heat distribution pipeline heat preservation energy-saving method.
Background technique
In the line transportation of fluid, as heating power, the conveying of tap water, the pipeline collection of crude oil is defeated, especially north of china in winter heat supply, the collection of oil thermal recovery viscous crude is defeated, realize by burying ground or aerial pipeline mostly, the medium temperature difference is very big in ambient temperature that its pipeline is outer and the pipe, present conveyance conduit is the external protection coating that coats composite silicate thermal insulation watt and be made of galvanized sheet iron or pitch glass cloth outside it, therefore heat is easy to see through the constantly outwards propagation of above-mentioned thermal insulation layer, heat loss is very big, give heating power or Crude Oil Transportation, especially the conveying in the heavy oil development process brings adverse effect, increased cost of production, reduce manufacturing efficiency, also caused the waste of the energy.
Summary of the invention
The object of the present invention is to provide a kind of heat distribution pipeline that can reduce to carry, especially the heat distribution pipeline heat preservation energy-saving method of the heat-energy losses in the oil transport pipeline course of conveying, raising pipeline transmission capacity, reduction cost of crude oil production.
The object of the present invention is achieved like this: coat resistant to elevated temperatures heat insulation layer, antiradiation layer, thermal insulation layer and external protection coating outside conveyance conduit successively, above-mentioned resistant to elevated temperatures heat insulation layer is an asbestos layer, the antiradiation layer is a clad aluminum foil, thermal insulation layer is a composite silicate thermal insulation watt, described protective coating is a galvanized sheet iron, also can be the pitch glass cloth.
Above-mentioned heat insulation layer is preferably the asbestos shingle plate.
Preferably be provided with heat-flash resistance insulation packing layer between above-mentioned antiradiation layer and thermal insulation layer, this packing layer is the sepiolite layer.
Between conveyance conduit and heat insulation layer, preferably brush resistant to elevated temperatures corrosion resistant coating.
Compared with prior art, the present invention has the advantage that can reduce heat distribution pipeline conveying, the especially heat-energy losses in the oil transport pipeline course of conveying, raising pipeline transmission capacity, reduce cost of crude oil production.
