Abstract
The utility model discloses an anti-corrosion insulation petroleum pipeline which comprises a pipeline outer layer and a pipeline inner layer, wherein an anti-corrosion coating is coated on the outer surface of the pipeline outer layer, an anti-corrosion coating is arranged on the inner wall of the pipeline inner layer, an insulation layer is arranged outside the pipeline inner layer, and a protective layer is arranged between the pipeline outer layer and the insulation layer. The anti-corrosion insulation petroleum pipeline has good insulation effect. Furthermore, the anti-corrosion coatings are arranged on the inside and outside of the anti-corrosion insulation petroleum pipeline, so that the pipeline can be protected from corrosion of corrosive liquid, and service life of the anti-corrosion insulation petroleum pipeline is prolonged.
Description
Technical field
The utility model relates to technical field of petroleum extraction, particularly relates to a kind of corrosion-resistant thermal insulation petroleum pipeline.
Background technique
At present, petroleum pipeline is in transportation process, especially for the petroleum pipeline exported, owing to being exported by sea-freight, in the process of navigation, need long-time (reaching several months) to stand humidity in ocean, there is corrosive sea wind piping and druming, thereby easily make petroleum pipeline the phenomenon of getting rusty, corroding occur, affect the quality of product, cause a large amount of economic losses.And in order to improve field crude oil production rate, usually to carry out secondary oil recovery and tertiary oil recovery, secondary oil recovery be by water filling addedly the way of stressor layer recover the oil; Tertiary oil recovery is to realize by methods such as gas inject, chemistry injection, microorganism injections, because underground viscosity of thickened oil is higher, in order to make it have good mobility, the liquid injected in oil recovery or the temperature of gas are higher, so need pipeline to have certain insulation effect.Secondary oil recovery and tertiary oil recovery flow in pipes used are steel pipe at present, and this steel pipe is bimetallic tube, and centre is vacuum tube, and the heat insulation effect of this pipe is bad, and not corrosion-resistant, and working life is short.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of corrosion protection thermal insulatnig petroleum pipeline, and a kind of high insulating effect can be provided, the corrosion protection thermal insulatnig petroleum pipeline that corrosion resistance and good and life-span are long.
For solving the problems of the technologies described above, a kind of corrosion protection thermal insulatnig petroleum pipeline that the utility model provides, comprise pipeline outer-layer and pipeline lining, be coated with corrosion-resistant finishes on described pipeline outer-layer outer surface, be provided with anticorrosive coat on the inwall of described pipeline lining, described pipeline lining is provided with thermal insulation layer outward, between described pipeline outer-layer and thermal insulation layer, is provided with protective coating.
Preferably, described corrosion-resistant finishes is the resin enamelled coating.
Preferably, described anticorrosive coat is the organosilicon anticorrosive coating.
Preferably, described thermal insulation layer is heat insulation foam glass insulating layer or polyurethane insulation coating.
Preferably, described protective coating is plastic protective film for plastics.
The utility model corrosion protection thermal insulatnig petroleum pipeline has good heat insulation effect, and the inside and outside anticorrosive coat that all is provided with, and can effectively avoid pipeline to be had corrosive liquid corrosion, extends its working life.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model corrosion protection thermal insulatnig petroleum pipeline structural representation.
Main description of reference numerals:
Pipeline outer-layer 1 corrosion-resistant finishes 2
Protective coating 3 thermal insulation layers 4
Pipeline lining 5 anticorrosive coats 6
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, the utility model corrosion protection thermal insulatnig petroleum pipeline, comprise pipeline outer-layer 1 and pipeline lining 5, be coated with corrosion-resistant finishes 2 on described pipeline outer-layer 1 outer surface, be provided with anticorrosive coat 6 on the inwall of described pipeline lining 5, described pipeline lining 5 is outer is provided with thermal insulation layer 4, between described pipeline outer-layer 1 and thermal insulation layer 4, is provided with protective coating 3.Described corrosion-resistant finishes 2 is the resin enamelled coating, and described anticorrosive coat 6 is the organosilicon anticorrosive coating, and described organosilicon anticorrosive coating, have anti-corrosion capability preferably, and that can effectively avoid pipeline to be injected into has corrosive liquid corrosion, extends its working life.Described thermal insulation layer 4 is heat insulation foam glass insulating layer or polyurethane insulation coating; Described protective coating 3 is plastic protective film for plastics.
Abovely by specific embodiment, the utility model is had been described in detail, but these not form restriction of the present utility model.In the situation that do not break away from the utility model principle, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection domain of the present utility model.
