The internal heating type polyurethane foam jacket pipe can realize direct heat tracing during crude oil transport process, has the advantages of good heat tracing effect, and low energy consumption, and can simplify the process flow of an oil-field monitor and optimize gathering and transportation pipelines.
Description
Technical field:
The utility model relates to a kind of tubing used in the oil pipeline course of conveying, relates to a kind of polyurethane foam jacket tube specifically.
Background technique:
In the crude oil transport field, extensively adopt oil pipe to carry, the polyurethane foam jacket tube then is a kind of pipeline material that is employed at most.Because the Northeast's cold weather in the winter time the time is frozen in the pipeline for preventing crude oil, often need add a heat traced pipeline in that oil transport pipeline is other, wherein provide heat energy, to guarantee the temperature of oil transport pipeline by circulating hot water or steam.In fact, this companion's hot mode is science not, and a large amount of heat energy is wasted and spills in the surrounding environment, and when building and construct, all needs to increase extra pipe laying cost.Thus, people consider whether can invent out a kind of tubing can directly be realized companion's heat in the process of conveying crude oil, so that the technical problem above solving.
The model utility content:
Lack a kind of tubing can directly be realized companion's heat in the process of conveying crude oil problem in the prior art in order to solve, the utility model provides a kind of internally heated type polyurethane foam jacket tube, this kind internally heated type polyurethane foam jacket tube can be implemented in the process of conveying crude oil directly companion's heat, has can simplify the petroleum transferring station technological process, optimize gathering line and characteristic of low energy consumption.
The technical solution of the utility model is: this kind internally heated type polyurethane foam jacket tube, comprise the yellow jacket exodermis of steel pipe and polyethylene, anticorrosive coat, heat conduction rete and polyurethane foam insulation layer from the inside to the outside successively distribute between the inwall of the outer wall of described steel pipe and the yellow jacket exodermis of polyethylene, wherein between heat conduction rete and polyurethane foam insulation layer carbon fiber electrothermal line is arranged, its two ends of this carbon fiber electrothermal line are by outside the insulation joint terminal fairlead.
The utlity model has following beneficial effect: take pipeline once prefabricated shaping in factory of such scheme, it is with the generator of carbon fiber electrothermal line as heat energy, by heat conducting film heat energy evenly is passed to the oil transportation steel pipe, heat energy has only sub-fraction to distribute by polyurethane foam insulation layer, but most heat energy still is kept in the whole petroleum pipeline, reduced heat-energy losses thus, energy consumption is lower.In addition, because the electric current that is added on the carbon fiber electrothermal line is adjustable, operator can make electric current increase as required or reduce, thereby it is arranged to accompany hot state or the stifled state that thaws, no longer need the special block apparatus that thaws thus, make the technological process of petroleum transferring station be greatly simplified, the setting of gathering line also can realize optimization, has reduced the construction cost and the user cost of device.
Description of drawings:
Fig. 1 is a structure sectional view of the present utility model.
Fig. 2 is the structural representation of polyurethane foam insulation layer in the utility model preferred embodiment 1.
Fig. 3 is the structural representation of polyurethane foam insulation layer in the utility model preferred embodiment 2.
The yellow jacket exodermis of 1-polyethylene among the figure, 2-steel pipe, 3-anticorrosive coat, 4-heat conduction rete, 5-polyurethane foam insulation layer, 6-draw-in groove, 7-carbon fiber electrothermal line.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this kind internally heated type polyurethane foam jacket tube, comprise the yellow jacket exodermis 1 of steel pipe 2 and polyethylene, anticorrosive coat 3, heat conduction rete 4 and polyurethane foam insulation layer 5 from the inside to the outside successively wherein distribute between the inwall of the outer wall of described steel pipe 2 and the yellow jacket exodermis 1 of polyethylene, wherein between heat conduction rete 4 and polyurethane foam insulation layer 5 carbon fiber electrothermal line 7 is arranged, these carbon fiber electrothermal line 7 its two ends are by outside the insulation joint terminal fairlead.When actual production, anticorrosive coat 3 can be selected the corrosion-resistant corrosion resistant coating of macromolecule for use, and the heat conduction rete can be selected the metal heat-conducting film for use.
In addition, for preventing that carbon fiber electrothermal line 7 in use is shifted, can on the inwall of described polyurethane foam insulation layer 5, have the draw-in groove 6 that is used for fixing carbon fiber electrothermal line, so just can on pipeline, determine the position of carbon fiber electrothermal line easily, be convenient to wiring and maintenance.
Distribute for the spatial position of carbon fiber electrothermal line outside steel pipe, may be thought of as straight line distribution or helix and distribute, simple when wherein the former makes, cost of production is low; And latter's complexity when making, but the companion's heat and the stifled effect of thawing all are better than the former.Accordingly, for realizing that the spatial position of carbon fiber electrothermal line outside steel pipe is distributed as straight line and distributes, as shown in Figure 2, the draw-in groove 6 on the polyurethane foam insulation layer is radially direct.And be to realize that the spatial position of carbon fiber electrothermal line outside steel pipe is distributed as helix and distributes, consider that for assembling described polyurethane foam insulation layer need be designed to be made of the halfbody of two symmetries, as shown in Figure 3, the draw-in groove on it distributes along the axis rotation.
Claims (4)
