Abstract
The present invention discloses a kind of steelframe reinforced petroleum pipeline; the outer surface of described outer tube body arranges one deck glass fibre reinforced plastics containment vessel; one circle steel ring is set in cavity between outer tube body and interior tube body; distance between the outer surface of this steel ring and outer tube body internal face equals the distance between the internal surface of this steel ring and interior tube body outer wall, evenly arranges some trapezoidal Steel Skeletons in the cavity in the cavity between described steel ring and outer tube body and between steel ring and interior tube body.Beneficial effect of the present invention is: by arranging one deck anticorrosive coat at the internal surface of interior tube body, arranges one deck glass fibre reinforced plastics containment vessel structure again, can guarantee thermal and insulating performance and the antiseptic property of inside and outside body at the outer surface of outer tube body; Between interior tube body outer surface and outer tube body internal surface, set up double-deck trapezoidal Steel Skeleton and in conjunction with steel ring, be conducive to the working life extending inside and outside body, greatly reduce maintenance cost.
Description
Technical field
The present invention relates to technical field of petroleum extraction, particularly relate to a kind of steelframe reinforced petroleum pipeline.
Background technique
At present, the pipe fitting being applied to the industries such as oil, chemical industry, electric power, boats and ships, metallurgy, machinery, weaving, food, building, 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 will carry out secondary oil recovery and tertiary oil recovery, secondary oil recovery is recovered the oil by the way of water filling addedly stressor layer; Tertiary oil recovery is realized by methods such as gas inject, chemistry injection, microorganism injections, because underground viscosity of thickened oil is higher, in order to make it have good mobility, the liquid injected in oil recovery or the temperature of gas higher, so need pipeline to have certain insulation effect.At present, secondary oil recovery and tertiary oil recovery flow in pipes used are steel pipe, and this steel pipe is bimetallic tube, and heat insulation effect is not good enough, and not corrosion-resistant, and working life is short; Between particularly 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.
Summary of the invention
The object of this invention is to provide a kind of heat insulation effect better, there is steelframe supporting protection structure, be conducive to the steelframe reinforced petroleum pipeline that increases the service life, to solve many deficiencies of prior art.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of steelframe reinforced petroleum pipeline; comprise outer tube body and interior tube body; the outer surface of described outer tube body arranges one deck glass fibre reinforced plastics containment vessel; one circle steel ring is set in cavity between outer tube body and interior tube body; distance between the outer surface of this steel ring and outer tube body internal face equals the distance between the internal surface of this steel ring and interior tube body outer wall, evenly arranges some trapezoidal Steel Skeletons in the cavity in the cavity between described steel ring and outer tube body and between steel ring and interior tube body.
The internal surface of described interior tube body arranges one deck anticorrosive coat, and each trapezoidal Steel Skeleton center position offers a wire casing.
The beneficial effect of steelframe reinforced petroleum pipeline of the present invention is: by arranging one deck anticorrosive coat at the internal surface of interior tube body, one deck glass fibre reinforced plastics containment vessel structure is set at the outer surface of outer tube body again, thermal and insulating performance and the antiseptic property of inside and outside body can be guaranteed; Between interior tube body outer surface and outer tube body internal surface, set up double-deck trapezoidal Steel Skeleton and in conjunction with steel ring, be conducive to the working life extending inside and outside body, greatly reduce maintenance cost.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the structural drawing of steelframe reinforced petroleum pipeline described in the embodiment of the present invention.
In figure: 1, outer tube body; 2, interior tube body; 3, glass fibre reinforced plastics containment vessel; 4, steel ring; 5, anticorrosive coat; 6, trapezoidal Steel Skeleton; 7, wire casing.
Embodiment
As shown in Figure 1, steelframe reinforced petroleum pipeline described in the embodiment of the present 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 and the internal surface of this interior tube body 2 arranges one deck anticorrosive coat 5, meanwhile, one deck glass fibre reinforced plastics containment vessel 3 is set again at the outer surface of outer tube body 1; A circle steel ring 4 is set between outer tube body 1 and interior tube body 2 and distance between the outer surface of this steel ring 4 and outer tube body 1 internal face equals between the internal surface of this steel ring 4 and interior tube body 2 outer wall distance in cavity, evenly arrange some trapezoidal Steel Skeletons 6 in cavity in cavity between described steel ring 4 and outer tube body 1 and between steel ring 4 and interior tube body 2, each trapezoidal Steel Skeleton 6 center position offers a wire casing 7.
