Abstract
The invention discloses an insulation petroleum pipe with a double-layer inner support structure. The insulation petroleum pipe comprises an outer pipe and an inner pipe. An anticorrosion layer and a high-temperature-resistant anti-oxidation layer are sequentially arranged on the inner and outer surfaces of the inner pipe respectively. The outer surface of the outer pipe is covered with a fiberglass protective case. A plurality of trapezoidal-projection double support structures are added to the inner wall of the outer pipe. Each trapezoidal-projection double support structure comprises two steel plates. An inner trapezoidal projection is added between each trapezoidal-projection double support structure and the inner pipe. The insulation petroleum pipe has the advantages that the anticorrosion layer and the high-temperature-resistant anti-oxidation layer are disposed on the inner and outer surfaces of the inner pipe respectively so that insulation performance and corrosion resistance of the inner pipe are enhanced; the multiple tiers of trapezoidal-projection support structures are added between the inner pipe and the outer pipe, and accordingly the service life of the outer pipe can be prolonged and maintenance cost is reduced greatly.
Description
Technical field
The present invention relates to technical field of petroleum extraction, relate in particular to a kind of double-deck inner supporting structure insulation petroleum pipeline.
Background technique
At present, be applied to oil, chemical industry, electric power, boats and ships, metallurgical, machinery, weaving, food, building, the pipe fitting of industries such as pharmacy all needs to possess higher intensity, resistance to pressure, corrosion-resistant, resistance to high temperature, therefore, in technical field of petroleum extraction, in order to improve the recovery rate of crude oil, usually to carry out secondary oil recovery and tertiary oil recovery, simultaneously, thermal insulation pipe is used for liquid, the conveying of gas and other media, at oil, chemical industry, space flight, military, central heat supply heat, central air-conditioner, the adiabatic heat-insulation engineering of pipelines such as municipal administration, its production and application make every effort to reduce significantly the consumption of the energy, thereby reduce environmental pollution and greenhouse effect.At present, this steel pipe heat insulation effect is not good enough, and not corrosion-resistant, and working life is short; Particularly between the general inside and outside two-tube body, namely also need to set up the necessary protection structure between outer tube body internal surface and the interior tube body outer surface, to seek long-range stability.Therefore, at above aspect, need make rational improvement.
Summary of the invention
The purpose of this invention is to provide a kind of heat insulation effect preferable, have the dual support structure, the short double-deck inner supporting structure insulation petroleum pipeline that is conducive to increase the service life, to solve many deficiencies of prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of double-deck inner supporting structure insulation petroleum pipeline; comprise outer tube body and interior tube body; inside and outside two surfaces of described interior tube body set gradually anticorrosive coat, high temperature resistant antioxidation coating respectively; described outer tube body outer surface parcel one deck glass fibre reinforced plastics containment vessel; set up some bucking ladder dual-support structures on the described outer tube body internal face; each bucking ladder dual-support structure is made up of two steel plates, sets up an interior bucking ladder between each bucking ladder dual-support structure and interior tube body.
The bucking ladder bottom is fixed on the interior tube body outer wall in described, and the cross section of described steel plate is isosceles trapezoid.
The beneficial effect of double-deck inner supporting structure insulation petroleum pipeline of the present invention is: by the inside and outside surface at interior tube body anticorrosive coat, high temperature resistant antioxidation coating are set respectively, can strengthen thermal and insulating performance, the antiseptic property of interior tube body, between interior tube body and outer tube body, set up multilayer bucking ladder supporting structure, be conducive to prolong the working life of outer tube body, reduce maintenance cost greatly.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural drawing of the described double-deck inner supporting structure insulation petroleum pipeline of the embodiment of the invention.
Among the figure: 1, outer tube body; 2, interior tube body; 3, high temperature resistant antioxidation coating; 4, glass fibre reinforced plastics containment vessel; 5, anticorrosive coat; 6, bucking ladder dual-support structure; 7, interior bucking ladder.
Embodiment
As shown in Figure 1; the described double-deck inner supporting structure insulation petroleum pipeline of the embodiment of the invention; comprise outer tube body 1 and interior tube body 2; described interior tube body 2 is arranged at the lumen centers position of outer tube body 1; in interior tube body 2; outer two surfaces set gradually anticorrosive coat 5 respectively; high temperature resistant antioxidation coating 3; described outer tube body 1 outer surface parcel one deck glass fibre reinforced plastics containment vessel 4; set up some bucking ladder dual-support structures 6 on described outer tube body 1 internal face; the steel plate that each bucking ladder dual-support structure 6 is isosceles trapezoid by two cross sections is formed, and sets up an interior bucking ladder 7 of being made up of steel plate and in this on bucking ladder 7 between each bucking ladder dual-support structure 6 and interior tube body 2; two bottom surfaces are separately fixed at interior tube body 2 outer wall down; bucking ladder dual-support structure 6 center portions.
