Abstract
The invention discloses an antifreezing petroleum pipeline, comprising a first outer pipe; a second outer pipe is arranged in the first outer pipe, a first thermal insulating layer is arranged between the first outer pipe and the second outer pipe, a second thermal insulating layer is arranged in the second outer pipe, and inner pipes are arranged in the second thermal insulating layer. By arranging the first thermal insulating layer, the second thermal insulating layer and multiple inner pipes, the structure has better thermal insulating effect, and petroleum in the pipeline is effectively prevented from being frozen under a relatively cold condition.
Description
Technical field
The present invention relates to petroleum transportation pipe technology field, especially, is related to a kind of antifreeze petroleum pipeline.
Background technology
Oil exploitation is generally located on the more severe area of environmental condition, and severe natural environment is for installed in ground
The harm of petroleum transportation pipeline it is larger, in prior art, petroleum transportation pipeline does not have antifreeze function, when more cold, pipe
Oil in road easily freezes, and affects the effect of petroleum transportation.
The content of the invention
Present invention aim at providing a kind of antifreeze petroleum pipeline, do not have to solve prior art petrochina transport pipeline
The technical problem of antifreeze function.
For achieving the above object, the present invention provides a kind of antifreeze petroleum pipeline, including：First outer tube, first outer tube
The second outer tube is inside provided with, the first heat-insulation layer, second outer tube are provided between first outer tube and second outer tube
In be provided with the second heat-insulation layer, be provided with inner tube in second heat-insulation layer.
Further, said inner tube is at least provided with one.
Further, first heat-insulation layer is made up of heat-barrier material.
Further, second heat-insulation layer is made up of heat-barrier material.
The invention has the advantages that：A kind of antifreeze petroleum pipeline of the present invention, the structure is protected by arranging first
Warm layer, the second heat-insulation layer and many inner tubes so that the structure has good heat insulation effect, under conditions of more cold,
Can effectively prevent the oil in pipeline from freezing.
Description of the drawings
Below with reference to figure, the present invention is further detailed explanation.The accompanying drawing for constituting the part of the application is used for
A further understanding of the present invention is provided, the schematic description and description of the present invention is used to explain the present invention, does not constitute
Inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 is the structural representation of the preferred embodiments of the present invention；
Description of reference numerals：1st, the first outer tube；2nd, the second outer tube；3rd, the first heat-insulation layer；4th, the second heat-insulation layer；5th, inner tube.
Specific embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing.
Fig. 1 is referred to, the preferred embodiments of the present invention provide a kind of antifreeze petroleum pipeline, including：First outer tube 1, institute
State in the first outer tube 1 and be provided with the second outer tube 2, between first outer tube 1 and second outer tube 2 the first heat-insulation layer is provided with
3, the second heat-insulation layer 4 is provided with second outer tube 2,4 are provided with inner tube 5 in second heat-insulation layer.The structure is by setting
Put the first heat-insulation layer 3, the second heat-insulation layer 4 and many inner tubes 5 so that the structure has good heat insulation effect, more trembling with fear
Under conditions of cold, can effectively prevent the oil in pipeline from freezing.
Preferably, at least provided with one, many inner tubes 5 are arranged in the second heat-insulation layer 4 said inner tube 5, can be very good
Play a part of insulation.
Preferably, first heat-insulation layer 3 is made up of heat-barrier material, extraneous cold air can be intercepted with oil and be opened, and prevents
Oil freezes.
Preferably, second heat-insulation layer 4 is made up of heat-barrier material.Extraneous cold air can be intercepted with oil and be opened, be prevented
Oil freezes.
As can be seen from the above description, the above embodiments of the present invention realize following technique effect：The structure is led to
Cross the first heat-insulation layer 3 of setting, the second heat-insulation layer 4 and many inner tubes 5 so that the structure has good heat insulation effect, compared with
Under conditions of for cold, can effectively prevent the oil in pipeline from freezing.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to；For the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
