Abstract
The utility model discloses a heat preservation petroleum pipeline of a double-layer inner supporting structure. The heat preservation petroleum pipeline of the double-layer inner supporting structure comprises an outer pipeline body and an inner pipeline body. An anticorrosive layer and a high temperature resistance and antioxidation layer are arranged on the inner surface and the outer surface of the inner pipeline body in sequence respectively, a layer of a glass fiber reinforced plastic protective shell wraps the outer surface of the outer pipeline body, a plurality of T-shaped stage double-supporting structures are additionally arranged on the inner wall face of the outer pipeline body, each T-shaped stage double-supporting structure is composed of two steel plates, and an inner T-shaped stage is additionally arranged between each T-shaped stage double-supporting structure and the inner pipeline body. The heat preservation petroleum pipeline of the double-layer inner supporting structure has the advantages that through the fact that the anticorrosive layer and the high temperature resistance and antioxidation layer are arranged on the inner surface and the outer surface of the inner pipe body respectively, the heat preservation and heat insulation performance and the anticorrosive performance of the inner pipeline body can be strengthened; the multilayer T-shaped stage supporting structures are additionally arranged between the inner pipeline body and the outer pipeline body, the fact that the service life of the outer pipeline body is facilitated, and maintenance cost is reduced greatly.
Description
Technical field
The utility model relates to technical field of petroleum extraction, relates in particular to a kind of double-deck inner supporting structure thermal insulatnig 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 the 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 the pipelines such as municipal administration, its production and application, make every effort to significantly reduce the consumption of the energy, thereby environmental contamination reduction 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 general inside and outside double-pipe body, namely also need between outer tube body internal surface and interior tube body outer surface to set up necessary safeguard structure, to seek long-range stability.Therefore, for above aspect, need to make rational improvement.
The model utility content
The purpose of this utility model be to provide a kind of heat insulation effect better, have the dual support structure, be conducive to the short double-deck inner supporting structure thermal insulatnig petroleum pipeline that increases the service life, to solve many deficiencies of prior art.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of double-deck inner supporting structure thermal insulatnig petroleum pipeline; comprise outer tube body and interior tube body; inside and outside two surfaces of described interior tube body set gradually respectively anticorrosive coat, high temperature resistant antioxidation coating; described outer tube body outer surface parcel one deck glass fibre reinforced plastics containment vessel; set up some bucking ladder dual-support structures on described outer tube body internal face; each bucking ladder dual-support structure is comprised of two steel plates, sets up an interior bucking ladder between each bucking ladder dual-support structure and interior tube body.
Described interior bucking ladder bottom is fixed on the interior tube body outer wall, and the cross section of described steel plate is isosceles trapezoid.
The beneficial effect of double-deck inner supporting structure thermal insulatnig petroleum pipeline described in the utility model 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, set up multilayer bucking ladder supporting structure between interior tube body and outer tube body, be conducive to extend the working life of outer tube body, greatly reduce maintenance cost.
