The invention discloses a flexible heat preservation pressing-resisting composite oil pipe which comprises a vinyl plastic conveying pipe. A non-metal fiber reinforcement layer is wound around the outer wall of the vinyl plastic conveying pipe, a heat preservation layer is arranged on the outer side of the reinforcement layer, an aluminum film is wound around the outer side of the heat preservation layer, and a plastic protection layer is arranged on the outer side of the aluminum film. All materials adopted in the flexible heat preservation pressing-resisting composite oil pipe are flexible materials, and therefore a pipe body of the oil pipe is flexible, the oil pipe can be continuously produced and coiled on a spool to be conveyed, cutting machining of the oil pipe can be greatly reduced, and production cost can be reduced. Due to the fact that the length of each oil pipe can be very large, the conduction steps of connecting the oil pipes can be greatly reduced, and construction cost can be reduced. In addition, heat preservation of five layers is adopted in the oil pipe, and therefore heat loss can be greatly reduced, the temperature of petroleum is higher than the precipitation temperature of paraffin in the conveying process all the time, and the situation that the paraffin is separated out and condensed on the inner wall of the oil pipe can be avoided.
Description
Technical field
The present invention relates to oil transportation equipment, be specifically related to the flexible heat-insulating resistance to compression composite oil pipe for transfer oil on ground.
Background technique
Carried by ground oil conduit after in petroleum production to ground.At present, the conventional ground oil conduit used in industry is made by metal pipe, during use, each ground oil conduit is interconnected to form transfer passage and carrys out transfer oil, but in use there is following shortcoming in above-mentioned conventional ground oil conduit: (1) is made up of metal pipe due to conventional ground oil conduit, so the body of oil pipe is rigidity, conveniently transport, usually need length oil pipe being cut into every root 6 ~ 18m; Because needs carry out repeatedly cutting process to oil pipe, thus can cost of production be increased, in addition, need each oil pipe to be connected with each other during use, thus also can increase construction cost.(2) heat insulation effect of conventional ground oil conduit is poor, oil temperature in transportation process can reduce fast, when the Precipitation Temperature of paraffin during temperature is lower than oil, paraffin can be separated out and be condensed on the inwall of oil pipe from oil, flow is reduced, thus the conveying efficiency of oil can be reduced, and the expense of paraffin on cleansing oil inner tube wall can be increased.
Summary of the invention

Advantage of the present invention is: the body of flexible heat-insulating resistance to compression composite oil pipe of the present invention is flexible, thus can transport in I-beam wheel continuous seepage coiling, and the insulation of this oil pipe and compression resistance excellent.
Accompanying drawing explanation
Fig. 1 is the structural representation of flexible heat-insulating resistance to compression composite oil pipe of the present invention.
Embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is described in further detail.
As shown in Figure 1; flexible heat-insulating resistance to compression composite oil pipe; comprise the polyvinyl plastics delivery pipe 1 of anticorrosion antiwear; the outer wall of polyvinyl plastics delivery pipe 1 is wound with the enhancement layer 2 of non-metallic fiber; thermal insulation layer 3 is had in the arranged outside of enhancement layer 2; also be wound with the aluminium film 4 of energy heat-insulation and heat-preservation in the outside of thermal insulation layer 3, have plastic protective layer 5 in the arranged outside of aluminium film 4.
In the present embodiment, polyvinyl plastics delivery pipe 1 is superhigh molecular weight polyethylene pipe, molecular weight is between 150 ten thousand to 600 ten thousand, utilize superhigh molecular weight polyethylene pipe nonpolarity and ganoid feature, make inwall not only anticorrosion antiwear but also not easily wax deposition, the fouling of polyvinyl plastics delivery pipe 1, meanwhile, polyvinyl plastics delivery pipe 1 has again certain heat insulation effect, the loss of oil heat can be reduced, play the first heavy heat insulation effect.Polyvinyl plastics delivery pipe 1 also can be heat-resisting polyethylene tube or high density polyethylene pipe.
In the present embodiment, enhancement layer 2 by PET dacron thread or aramid fiber yarn or superhigh molecular weight polyethylene fibers silk in turn spiral winding form, the thickness of enhancement layer 2 is determined according to actual bearing requirements, enhancement layer 2 can improve the compression resistance of oil pipe greatly, the compression resistance of the oil pipe that the compression resistance of oil pipe of the present invention can be made with metal pipe is suitable, and enhancement layer 2 also plays the second heavy heat insulation effect simultaneously.
In the present embodiment, thermal insulation layer 3 forms by nanometer felt is coated, when operating temperature is not more than 100 DEG C, the thermal conductivity of nanometer felt is not more than 0.020W/ (mK), the thickness of nanometer felt is at 3 ~ 20mm, and nanometer felt has excellent thermal insulation property, can play triple heat insulation effect, nanometer felt outer felt around the thermal radiation that outwards can disperse to internal reflection of aluminium film 4, thus can quadruple heat insulation effect be played.
In the present embodiment, plastic protective layer 5 is extruded by extruder and is made, and plastic protective layer 5 is polyolefin layer, and plastic protective layer 5 can not only play the effect of protection oil pipe, and can also play resistance to compression and the 5th heavy heat insulation effect.
The beneficial effect of flexible heat-insulating resistance to compression composite oil pipe of the present invention is: flexible heat-insulating resistance to compression composite oil pipe material therefor of the present invention is flexible material, so the body of this oil pipe is flexible, thus can transport in I-beam wheel continuous seepage coiling, this oil pipe can make the length of every root 1 kilometer or longer, thus the cutting process of oil pipe can be greatly reduced, and then can cost of production be reduced, and because the length of the every root of this oil pipe can be very long, thus the interconnective construction sequence of oil pipe can be greatly reduced, thus construction cost can be reduced.In addition, oil pipe of the present invention have employed five and is heavily incubated, the loss of heat can be greatly reduced, make the Precipitation Temperature of the temperature of oil all the time higher than paraffin in transportation process, thus paraffin can be avoided to separate out and condense on the inwall of oil pipe, and then greatly can improve the conveying efficiency of oil, simultaneously due to polyvinyl plastics delivery pipe, its frictional resistance is low, when with steel pipe with bore, the quantity delivered of its liquid is greater than steel pipe, low in energy consumption.
