Abstract
The utility model discloses a heat insulating pipeline. The heat insulating pipeline comprises a pipe body and is characterized in that a heat insulating layer and a high temperature resistant layer are arranged on the inner wall of the pipe body from inside to outside in sequence; an aluminum foil layer is arranged between the heat insulating layer and the high temperature resistant layer; and an external protective layer is arranged at the outer wall of the pipe body. The heat insulating pipeline disclosed by the utility model has the characteristics of lower production cost and better heat insulating effect.
Description
Technical field
The utility model relates to building material field, relates in particular to the insulation pipe of the lower and high insulating effect of a kind of cost of production.
Background technique
Along with the continuous development of industry, city-building is more and more.Application to large-scale pipelines such as water delivery, oil transportation, gas transmissions is also more and more.Quality requirement to pipeline is higher, especially the decay resistance and the thermal insulation property of pipeline is had relatively high expectations.Common pipe is soaked the most frequently used anti-corrosion method and is had in that water is medium-term and long-term: zinc-plated anticorrosion, resinize and carry out anticorrosion, rust proof paint and add bituminous paint and carry out anticorrosion.Yes that hot dip galvanizing pipe is best for general water quality, and corrosion resistant is anti-than higher temperature.If there is not condition, it also is all well and good adding the protective coating that glass yarn makes with resin, comparatively corrosion-resistant.That just adds bituminous paint with rust proof paint or pitch also becomes if there is not condition again.But no matter use which kind of method, the initial rust cleaning work of steel pipe is most important, and it is related to the corrosion-resistant success or failure.With back two kinds of methods, the floating rust of the outside of at first must checking on eliminates, and just can carry out next procedure.If not, just can not play protective action.With regard to being incubated this characteristic, large batch of insulation pipe has appearred in recent years.Insulation pipe is widely used in the transmission pipeline network of liquid, gas, chemical pipeline heat insulating work oil, chemical industry, central heat supply heat supply network, central air-conditioner ventilation duct, municipal engineering etc.The high temperature prefabricated direct-buried thermal insulation pipe is a kind of good heat insulating, adds safe and reliablely, and the direct-burried that engineering cost is low is heat preservation pipe prefabricated.Effectively solved in the central heat supply of cities and towns the defeated heat of 130 ℃ of-600 ℃ of high temperature with the insulation of prefabricated direct-buried thermal insulation pipe, slide and lubricate and the waterproof problem of exposed pipe end.The high temperature prefabricated direct-buried thermal insulation pipe not only has advanced technology, the practicability that traditional trench and built on stilts channelling hardly match, but also has remarkable social benefit and economic benefit, also is the effective measure of heating energy-saving.
Publication number is CN 2407215; Open day discloses a kind of uncompensated thermal insulation pipe for the Chinese patent document of 2000.11.22; Constitute by steel pipe, thermal insulation layer, glass fibre reinforced plastics casing; It is characterized in that: the two ends of steel pipe are welded with two back-up rings, and the steel pipe at glass fibre reinforced plastics casing and two back-up rings and back-up ring place sticks to one, and through two back-up rings steel pipe are given and to add axial pressure.The thermal insulation layer of this patent documentation is to be made up of bearing ring and cellucotton that the thermal insulating material of hard is processed, and bearing ring uses a period of time to damage easily, and the heat insulation effect of cellucotton is also relatively poor, can not make the heat insulation effect of pipeline in shape for a long time.
The model utility content
The utility model aims to provide the lower and good heat insulation effect insulation pipe of a kind of cost of production,
The utlity model has that cost of production is lower, the good heat insulation effect characteristics.
In order to realize the foregoing invention purpose, the technological scheme that the utility model adopts is:
Insulation pipe comprises body, it is characterized in that: said inboard wall of tube body is disposed with thermal insulation layer and high-temperature-resistant layer from inside to outside, is provided with aluminium foil layer between said thermal insulation layer and the high-temperature-resistant layer, and said tube wall is provided with outer protective layer.
Said thermal insulation layer is a polyurethane layer.
Said high-temperature-resistant layer is a ceramic layer.
The thickness of said aluminium foil layer is 0.1-0.4mm.
Said outer protective layer is galvanized iron cortex or frp layer.
The thickness of said outer protective layer is 1-4mm.
The said polyurethane full name of the utility model is a polyurethane, is the general designation that contains the macromolecular compound of repetition carbamate groups on the main chain; Be to form by organic diisocyanate or polyisocyanates and dihydroxy or polyol addition polymerization.
The said aluminium foil of the utility model is soft metallic thin film, not only has advantages such as protection against the tide, airtight, shading, wear-corrosion resistance, guarantor be fragrant, nonpoisonous and tasteless, but also has silvery white gloss.
The beneficial effect of the utility model mainly shows the following aspects:
One, through being disposed with thermal insulation layer at inboard wall of tube body, thermal insulation layer is a polyurethane layer, and polyurethane is to be formed by organic diisocyanate or polyisocyanates and dihydroxy or polyol addition polymerization.Its heat insulation effect is fairly good.
Two, high-temperature-resistant layer is set, high-temperature-resistant layer is a ceramic layer, and resistance to high temperature is fairly good.
Three, between thermal insulation layer and high-temperature-resistant layer, be provided with aluminium foil layer, aluminium foil is soft metallic thin film, not only has advantages such as protection against the tide, airtight, shading, wear-corrosion resistance, guarantor be fragrant, nonpoisonous and tasteless, but also has silvery white gloss; Can further improve the heat preservation property of body.
Four, the thickness of outer protective layer is set to 1-4mm, has reduced the cost of production of body when guaranteeing the tube wall wear resistance.
