Abstract
The invention discloses a petroleum pipeline. The wall of the pipeline is composed of an outer layer, a heat preservation layer and an inner layer from outside to inside, heater strips are arranged between the inner layer and the heat preservation layer, and the inner surface of the inner layer is of a waved uneven structure. The wall of the petroleum pipeline is composed of the three layers, the heater strips are added to the wall of the pipeline and can heat the pipeline, generated heat is not prone to dissipation under the effect of the heat preservation layer, the viscosity of petroleum in the pipeline is lowered, petroleum fluidity is good, and the blocking phenomenon is reduced.
Description
Technical field
The present invention relates to oil transportation device technical field, especially a kind of petroleum pipeline for oil transportation.
Background technique
Must be transported to corresponding machining sector after petroleum production, just can more preferably be utilized, wherein the petroleum pipeline of transfer oil is then absolutely necessary equipment.Existing petroleum pipeline is straight tube structure, due to the viscosity of oil own, is easy to stick on tube wall, results in blockage, make troubles to transfer oil.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of petroleum pipeline, transfer oil is convenient, not easily blocks.
In order to realize foregoing invention object, the invention provides following technological scheme: a kind of petroleum pipeline, this tube wall is made up of skin from outside to inside, thermal insulation layer and internal layer, between internal layer and thermal insulation layer, be provided with heating wire; The internal surface of internal layer is waveform concaveconvex structure.
Further, this heating wire is be spirally wound on the outer surface of internal layer.
Further, this heating wire insulation layer institute is coated.
Compared with prior art, the present invention has the following advantages: tube wall is made up of three-decker, and adds heating wire wherein, can heat, and the heat produced is under thermal insulation layer effect, not easily scatters and disappears, oil viscosity in pipeline is reduced, good fluidity, decrease choking phenomenon and occur.
Accompanying drawing explanation
Fig. 1 is the structural representation of petroleum pipeline of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of petroleum pipeline as shown in Figure 1, this tube wall is made up of skin 1 from outside to inside, thermal insulation layer 2 and internal layer 3, is provided with heating wire 4 between internal layer 3 and thermal insulation layer 2; The heat that such heating wire 4 produces all realizes the heating to internal layer 3, thus significantly reduces the viscosity of oil in pipeline, improves oil flow, decreases blocking.
The internal surface of internal layer 4 is waveform concaveconvex structure, makes the oil flowed constantly through speedup and moderating process, when internal diameter is minimum just in the pipeline of speedup, now there is the jet phenomenon of Venturi tube, reduce the adhesive of oil, improve mobility, thus avoid occurring blocking; Be applicable to various oil transportation.
Heating wire 4 be spiral wrap on the outer wall of internal layer 3, can magnetic field heating oil, the heating of pipeline PetroChina Company Limited. can be passed to through heat transfer again, make heating effect best, reduce and occur adhesion phenomenon at tube wall, thus avoid occurring blocking, be applicable to various oil transportation.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (3)
1. a petroleum pipeline, is characterized in that: this tube wall is made up of skin from outside to inside, thermal insulation layer and internal layer, between internal layer and thermal insulation layer, be provided with heating wire; The internal surface of internal layer is waveform concaveconvex structure.
2. petroleum pipeline as claimed in claim 1, is characterized in that: this heating wire is be spirally wound on the outer surface of internal layer.
3. petroleum pipeline as claimed in claim 2, is characterized in that: this heating wire insulation layer institute is coated.
