Abstract
The utility model discloses a kind of petroleum pipeline with thermal insulation layer, described pipeline comprises interior pipe and is set in the outer tube outside described interior pipe, closed cavity is formed between described interior pipe and described outer tube, thermal insulation layer is provided with in described cavity, described thermal insulation layer is followed successively by reflective insulation layer, foam layer and rubber layer by interior pipe to outer tube direction, outside described outer tube, be enclosed with one deck watertightness barrier, described watertightness barrier is also provided with one deck nanometer layer outward.The utility model structure is simple, and good heat preservation performance, is provided with watertightness barrier in outer tube, can play the effect preventing seepage, in addition, is also provided with anticorrosive coat inside interior pipe, avoids causing corrosion to pipeline, and Security improves.
Description
Technical field
The utility model relates to a kind of insulation pipe, particularly relates to a kind of petroleum pipeline with thermal insulation layer.
Background technique
Pipeline transport is with the mode of movement of pipeline as a kind of long distance delivery liquids and gases goods and materials of means of transportation, being a kind of special in the means of transportation of grown place to market transfer oil, coal and chemical products, is the special constituent element of line haul in consolidated delivery net.When utilizing pipeline to carry out petroleum transportation, at some cold zone, petroleum pipeline cannot normally can work because of cold weather, there will be and break or situation that in pipeline, oil flow is not smooth, so can ensure that the temperature equalization in petroleum pipeline is extremely important.
Model utility content
Occur the problem of breaking or oil flow is not smooth to solve the petroleum pipeline in the lower situation of temperature existed in prior art, the utility model provides a kind of petroleum pipeline with thermal insulation layer.
The technical solution of the utility model is: a kind of petroleum pipeline with thermal insulation layer, described pipeline comprises interior pipe and is set in the outer tube outside described interior pipe, closed cavity is formed between described interior pipe and described outer tube, thermal insulation layer is provided with in described cavity, described thermal insulation layer is followed successively by reflective insulation layer, foam layer and rubber layer by interior pipe to outer tube direction, outside described outer tube, be enclosed with one deck watertightness barrier, described watertightness barrier is also provided with one deck nanometer layer outward.
Preferably, anticorrosive coat is provided with inside described interior pipe.
The beneficial effects of the utility model: the utility model structure is simple, and good heat preservation performance, is provided with watertightness barrier in outer tube, can play the effect preventing seepage, in addition, is also provided with anticorrosive coat inside interior pipe, avoids causing corrosion to pipeline, Security improves.
Accompanying drawing explanation
Fig. 1 is the partial sectional view that the utility model has the petroleum pipeline of thermal insulation layer;
In figure: pipe in 1,2 cavitys, 3 watertightness barriers, 4 outer tubes, 5 anticorrosive coats, 6 reflective insulation layers, 7 foam layers, 8 rubber layers, 9 nanometer layer.
Embodiment
By reference to the accompanying drawings the mode of execution that the utility model provides is described in further detail:
As shown in Figure 1, a kind of petroleum pipeline with thermal insulation layer, the outer tube 4 that described pipeline comprises interior pipe 1 and is set in outside described interior pipe 1, closed cavity 2 is formed between described interior pipe 1 and described outer tube 4, thermal insulation layer is provided with in described cavity 2, described thermal insulation layer is followed successively by reflective insulation layer 6, foam layer 7 and rubber layer 8 by interior pipe to outer tube direction, is enclosed with one deck watertightness barrier 3 outside described outer tube, and described watertightness barrier is also provided with one deck nanometer layer 9 outward.
Preferably anticorrosive coat 5 is provided with inside described interior pipe in the present embodiment.
The utility model structure is simple, and good heat preservation performance, is provided with watertightness barrier in outer tube, can play the effect preventing seepage, in addition, is also provided with anticorrosive coat inside interior pipe, avoids causing corrosion to pipeline, and Security improves.
In this description, the utility model is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
