Abstract
The utility model discloses a kind of thermal-insulating type petroleum pipeline, including outer tube and the inner tube being positioned at outer tube, be followed successively by heat-conducting layer and elastic heat preserving layer between outer tube and inner tube from outside to inside, and the cross-sectional area of elastic heat preserving layer is more than the cross-sectional area of heat-conducting layer；On outer tube outer wall, the detachable heating and thermal insulation layer that is coated with, heating and thermal insulation layer is provided with buckle.This utility model uses the petroleum pipeline of inner and outer pipes structure, and arranges heating and thermal insulation layer on outer tube outer wall, is transferred to from outside to inside by heat in inner tube oil, improves the mobility of hot oil, the less viscosity of oil, decreases oil and adheres on inner pipe.
Description
Technical field
This utility model relates to petroleum pipeline equipment technical field, particularly a kind of thermal-insulating type petroleum pipeline.
Background technology
Must transport corresponding machining sector after oil exploitation, just can more preferably be utilized, wherein the petroleum pipeline of transfer oil is then requisite equipment.Existing petroleum pipeline is straight tube structure, due to the viscosity of oil own, it is easy to stick on tube wall, result in blockage, make troubles to transfer oil.
Utility model content
The purpose of this utility model is to provide one, solves the susceptible to plugging technical problem of petroleum pipeline in prior art.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of thermal-insulating type petroleum pipeline, including outer tube and the inner tube being positioned at outer tube, is followed successively by heat-conducting layer and elastic heat preserving layer from outside to inside, and the cross-sectional area of elastic heat preserving layer is more than the cross-sectional area of heat-conducting layer between outer tube and inner tube；On outer tube outer wall, the detachable heating and thermal insulation layer that is coated with, heating and thermal insulation layer is provided with buckle.
Heating and thermal insulation layer on outer tube outer wall is for heating the inner tube of inside, heating and thermal insulation layer can be heated itself, and self has heat insulation function, transfer heat to the heat-conducting layer on outer tube wall again, heat-conducting layer transfers heat to the elastic heat preserving layer on outer wall of inner tube again, and elastic heat preserving layer, for heating the oil of inner tube and internal flow, improves the mobility of oil, reduce the viscosity of oil, prevent from being formed fouling on inner tubal wall.
Elastic heat preserving layer not only can be incubated, and possesses certain elasticity, and when inner tube bears outside pressure, elastic heat preserving layer can absorb a certain amount of pressure.
Heating and thermal insulation layer on outer tube outer wall is detachable cladding, is coated on outer tube outer wall by buckle, can choose whether according to actual needs to need cladding, the such as pipeline of open air in winter use to be the most more necessary to be coated with heating and thermal insulation layer.
The cross-sectional area sum that cross-sectional area is elastic heat preserving layer and heat-conducting layer of heating and thermal insulation layer described in the utility model.Ensure that heating and thermal insulation layer has enough heats to be transferred in the oil of inner tube and inside thereof largely.
This utility model uses technique scheme, has an effect will be apparent below:
This utility model uses the petroleum pipeline of inner and outer pipes structure, and arranges heating and thermal insulation layer on outer tube outer wall, is transferred to from outside to inside by heat in inner tube oil, improves the mobility of hot oil, the less viscosity of oil, decreases oil and adheres on inner pipe.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 shows overall structure of the present utility model.
Detailed description of the invention
For making the purpose of this utility model and technical scheme clearer, below in conjunction with this utility model embodiment, the technical solution of the utility model is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present utility model rather than whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art are obtained on the premise of without creative work, broadly fall into the scope of this utility model protection.
A kind of thermal-insulating type petroleum pipeline, the technical characteristic such as including outer tube 1, inner tube 2, heat-conducting layer 3, elastic heat preserving layer 4, heating and thermal insulation layer 5 and buckle 6.
Embodiment 1
A kind of thermal-insulating type petroleum pipeline, including outer tube and the inner tube being positioned at outer tube, is followed successively by heat-conducting layer and elastic heat preserving layer from outside to inside, and the cross-sectional area of elastic heat preserving layer is more than the cross-sectional area of heat-conducting layer between outer tube and inner tube；On outer tube outer wall, the detachable heating and thermal insulation layer that is coated with, heating and thermal insulation layer is provided with buckle.
The cross-sectional area sum that cross-sectional area is elastic heat preserving layer and heat-conducting layer of heating and thermal insulation layer described in the utility model.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff can carry out various change and amendment completely in the range of without departing from this utility model technological thought.The content that the technical scope of this utility model is not limited in description, it is necessary to determine its technical scope according to right.
Claims (2)
1. a thermal-insulating type petroleum pipeline, it is characterised in that include outer tube and be positioned at the inner tube of outer tube, is followed successively by heat-conducting layer and elastic heat preserving layer from outside to inside, and the cross-sectional area of elastic heat preserving layer is more than the cross-sectional area of heat-conducting layer between outer tube and inner tube；On outer tube outer wall, the detachable heating and thermal insulation layer that is coated with, heating and thermal insulation layer is provided with buckle.
Thermal-insulating type petroleum pipeline the most according to claim 1, it is characterised in that the cross-sectional area sum that cross-sectional area is elastic heat preserving layer and heat-conducting layer of described heating and thermal insulation layer.
