Abstract

The invention discloses a petroleum pipeline. The petroleum pipeline is sequentially formed by the three layers of a reinforcing layer, a thermal insulating layer and an inner wall layer from the outer part to the inner part, the inner wall of the pipeline on the cross section is of a regular polygonal structure, and the number of edges is 8-16. Any edge of the regular polygon is spirally arranged by taking the axis of the pipeline as a spiral axis. The petroleum pipeline adopting a trilayer structure has strong thermal insulating performance, conveniently delivers petroleum, has great pressure resistance, cannot be easily broken and improves safety. The arrangement of the inner wall of the pipeline into the spiral regular polygonal structure improves petroleum flowing turbulence and reduces viscosity.

Description

Petroleum pipeline
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, being made up of three layers of being followed successively by reinforced layer, thermal insulation layer and internal layer from outside to inside, on this cross-section of pipeline, inwall is regular polygon structure, and limit number is 8 ~ 16; The arbitrary limit of this regular polygon is that screw axis carries out spiral setting with conduit axis.
Further, the pitch of this spiral is 3 ~ 5 times of outer diameter tube.
Compared with prior art, the present invention has the following advantages: adopt the petroleum pipeline that three-decker is formed, and thermal insulation property is strong, and transfer oil is convenient; Resistance to pressure is good, not easily breakage occurs, and improves Security; And inner-walls of duct is set to the regular polygon structure of spiral setting, improve the turbulent flow of live oil, reduce adhesion.
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, by being followed successively by from outside to inside, reinforced layer 1, thermal insulation layer 2 and internal layer 3 three layers form, on this cross-section of pipeline, inwall is regular polygon structure, and limit number is 8 ~ 16; The arbitrary limit of this regular polygon is that screw axis carries out spiral setting with conduit axis.
Adopt in the periphery of internal layer 3 coated thermal insulation layer 2, make hot oil oil viscosity in internal layer 3 low, good fluidity; Again at thermal insulation layer 2 outer cladding reinforced layer 1, improve the crushing resistance of integrated piping, not easily fracture phenomena occurs.
And by cross-section of pipeline, its inwall is regular polygon structure, and be that screw axis carries out spiral setting with conduit axis; , there is radial shear power all the time in the oil flow in pipeline, decreases laminar flow phenomenon and occur, thus reduce oil adhesive, improve flow velocity.
The pitch of preferred this spiral of employing is 3 ~ 5 times of outer diameter tube, exceeds the flow velocity affecting oil, just in time overcomes again the possibility that live oil adheres to tube wall.
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 (2)

1. a petroleum pipeline, is characterized in that: form by three layers that are followed successively by reinforced layer, thermal insulation layer and internal layer from outside to inside, and on this cross-section of pipeline, inwall is regular polygon structure, and limit number is 8 ~ 16; The arbitrary limit of this regular polygon is that screw axis carries out spiral setting with conduit axis.
2. petroleum pipeline as claimed in claim 1, is characterized in that: the pitch of this spiral is 3 ~ 5 times of outer diameter tube.
