Abstract
The invention discloses a stable-structure type petroleum pipeline. The stable-structure type petroleum pipeline comprises an inner pipe, a heat insulation layer and an outer pipe which are sequentially arranged from inside to outside. Reinforcing ribs are arranged between the inner pipe and the heat insulation layer. The section of each reinforcing rib is of a V shape. The whole reinforcing ribs are spirally arranged on the outer wall of the inner pipe. The portion between the inner pipe and the heat insulation layer is filled with a heat insulation material layer. The stable-structure type petroleum pipeline is stable in structure and good in heat insulation effect.
Description
Technical field
The present invention relates to petroleum pipeline field, particularly, relate to a kind of structural stability type petroleum pipeline.
Background technique
oil is in oil recovery process, because oil paraffin content is too high, carry oil concentration large, often cause oil transport pipeline oil transportation difficulty, especially in cold season, heating on petroleum pipeline is needed to solve the problem of oil transportation difficulty, existing electric heater for petroleum pipeline is generally be arranged on petroleum pipeline outer wall, and petroleum pipeline is in order to be incubated, as " a kind of thermal insulatnig petroleum pipeline road " of application publication number CN 104089149 A, its inner core adopted from inside to outside more, thermal insulation layer, bitumen layer, urceolus, and the stiffening rib be arranged between thermal insulation layer and inner core, thermal insulation layer is utilized to reduce scattering and disappearing of the interior oil heat of pipe, but, it comes with some shortcomings, the heavier mass of bitumen layer, make to increase weight to the load of stiffening rib, and be air between thermal insulation layer and inner core, its heat insulation effect is not good.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of structural stability type petroleum pipeline, its structural stability and high insulating effect.
The present invention's adopted technological scheme that solves the problem is:
A kind of structural stability type petroleum pipeline, comprise the interior pipe, thermal insulation layer and the outer tube that set gradually from inside to outside, stiffening rib is provided with between described interior pipe and thermal insulation layer, the cross section of described stiffening rib is " V " type, the overall curl of described stiffening rib is arranged on the outer wall of interior pipe, is filled with adiabator layer between described interior pipe and thermal insulation layer.
The present invention improves on the basis of existing technology, one: save bitumen layer, reduces its quality, namely reduces the load of stiffening rib, strengthens the stability of petroleum pipeline structure; Its two: by the gap-fill adiabator layer between interior pipe and thermal insulation layer, utilize adiabator layer to be again incubated petroleum pipeline, strengthen its heat insulation effect; Its three, be cross section by the architecture advances of stiffening rib be " V " type, form subtriangular between the tube wall between " V " shaped material and interior pipe or thermal insulation layer, further strengthen the stability of reinforcing rib structure; Its four: by stiffening rib whole installation curl, strengthen the stability of its structure.
As preferably, in order to cost-saving and strengthen insulation effect, described adiabator layer is foam layer.Utilize foam layer as adiabator layer, not only quality is light for it, and high insulating effect.
As preferably, in order to further strengthen the stability of petroleum pipeline structure, be connected with interior pipe and thermal insulation layer respectively bottom " V " type of adjacent two stiffening ribs.
As preferably, in order to further strengthen the stability of petroleum pipeline structure, described stiffening rib has 4 at least.
Further, described stiffening rib has 4, and lays respectively at the two ends of two orthogonal diameters of interior pipe.
To sum up, the invention has the beneficial effects as follows:
1, the present invention saves bitumen layer in prior art, reduces its quality, namely reduces the load of stiffening rib, strengthens the stability of petroleum pipeline structure.
2, the present invention is by the gap-fill adiabator layer between interior pipe and thermal insulation layer, utilizes adiabator layer to be again incubated petroleum pipeline, strengthens its heat insulation effect.
3, the architecture advances of stiffening rib is cross section by the present invention is " V " type, forms subtriangular, further strengthen the stability of reinforcing rib structure between the tube wall between " V " shaped material and interior pipe or thermal insulation layer.
4, the present invention is by stiffening rib whole installation curl, strengthens the stability of its structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark and corresponding component title in accompanying drawing: 1, interior pipe; 2, thermal insulation layer; 3, outer tube; 4, stiffening rib; 5, adiabator layer.
Embodiment
Below in conjunction with embodiment and accompanying drawing, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
