Abstract
The utility model discloses a detachable double-layer petroleum pipe fitting. The detachable double-layer oil pipe fitting comprises an external pipe body and an internal pipe body. A glass steel protective shell is arranged on the periphery of the external pipe body. A high-temperature-resistant anti-oxidation layer is additionally arranged between the glass steel protective shell and the outer wall face of the external pipe body. Four drawing-and-inserting-type steel plates which are in a prism shape are arranged in a cavity located between the internal pipe body and the external pipe body. The drawing-and-inserting-type steel plates are distributed in the cavity between the internal pipe body and the external pipe body in a surrounding mode with the center point of the internal pipe body as the circle center. The detachable double-layer petroleum pipe fitting has the advantages that the glass steel protective shell and the anti-oxidation layer wrap the outer surface of the external pipe body, so that the anti-corrosion performance and the anti-oxidation performance can be improved; the four drawing-and-inserting-type steel pipes which are in the prism shape are paved in the cavity located between the internal pipe body and the external pipe body, so that the improvement of the stability of the internal pipe body is facilitated, the service life of the internal pipe body is prolonged and the maintenance cost is greatly reduced.
Description
Technical field
The utility model relates to technical field of petroleum extraction, relates in particular to a kind of dismountable double-deck petroleum pipe fitting.
Background technique
At present, the pipe fitting that is 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.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, in order to make it have good mobility, the liquid that injects in oil recovery or the temperature of gas are higher, so need pipeline to have certain insulation effect, thermal insulation pipe is used for the conveying of liquid, gas and other media.At present, this steel pipe heat insulation effect is not good enough, and not corrosion-resistant, and working life is short; It is reasonable not that the protection structure of special outer tube body arranges, and simultaneously, is not easy to dismounting for the different application scene.Therefore, for above aspect, need to make rational improvement.
The model utility content
The purpose of this utility model is to provide the dismountable double-deck petroleum pipe fitting that a kind of heat insulation effect is better, have Multiple Protective Structure, be convenient to dismounting, be conducive to increase 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 dismountable double-deck petroleum pipe fitting comprises outer tube body and interior tube body, and described outer tube body periphery arranges the glass fibre reinforced plastics containment vessel and set up the high temperature resistant antioxidation coating of one deck between glass fibre reinforced plastics containment vessel and outer tube body outer wall; Simultaneously, but four blocks of draw and insert-type steel plates that are the quadrangular shape are set in the inner chamber between interior tube body and outer tube body, but these draw and insert-type steel plates take the interior tube body central point as the center of circle around in the inner chamber that is distributed between interior tube body and outer tube body.
The internal surface of described interior tube body arranges one deck anticorrosive coat, outer surface parcel one deck glass wool thermal insulation separation thermosphere of described interior tube body.
The beneficial effect of dismountable double-deck petroleum pipe fitting described in the utility model is: at the outer surface parcel glass fibre reinforced plastics containment vessel of outer tube body, high temperature resistant antioxidation coating, can improve antiseptic property and the oxidation resistance of outer tube body; But lay four blocks of draw and insert-type steel plates that are the quadrangular shape in the cavity between interior tube body and outer tube body, be conducive to improve the stability of interior tube body, extend the working life of interior tube body, greatly reduce maintenance cost.
Description of drawings
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is the described dismountable double-deck petroleum pipe fitting figure of the utility model embodiment.
In figure: 1, outer tube body; 2, interior tube body; 3, glass fibre reinforced plastics containment vessel; 4, high temperature resistant antioxidation coating; 5, anticorrosive coat; 6, glass wool thermal insulation separation thermosphere; But 7 draw and insert-type steel plates.
Embodiment
As shown in Figure 1, the described dismountable double-deck petroleum pipe fitting of the utility model embodiment, 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, the thickness of described anticorrosive coat is 0.1mm, outer surface at interior tube body 1 wraps up one deck glass wool thermal insulation separation thermosphere 6 again, and the thickness of described glass wool thermal insulation separation thermosphere is 0.25mm; Described outer tube body 1 periphery arranges glass fibre reinforced plastics containment vessel 3 and set up the high temperature resistant antioxidation coating 4 of one deck between glass fibre reinforced plastics containment vessel 3 and outer tube body 1 outer wall, and the thickness of described high temperature resistant antioxidation coating is 0.2mm; Simultaneously, but four blocks of draw and insert-type steel plates 7 that are the quadrangular shape are set in the inner chamber between interior tube body 2 and outer tube body 1, but these draw and insert-type steel plates 7 are distributed in take interior tube body 2 central points as center of circle annular array type in inner chamber between interior tube body 2 and outer tube body 1.
Claims (3)
1. a dismountable double-deck petroleum pipe fitting, comprise outer tube body and interior tube body, it is characterized in that:
Described outer tube body periphery arranges the glass fibre reinforced plastics containment vessel and set up the high temperature resistant antioxidation coating of one deck between glass fibre reinforced plastics containment vessel and outer tube body outer wall; Simultaneously, but four blocks of draw and insert-type steel plates that are the quadrangular shape are set in the inner chamber between interior tube body and outer tube body, but these draw and insert-type steel plates take the interior tube body central point as the center of circle around in the inner chamber that is distributed between interior tube body and outer tube body.
2. a kind of dismountable double-deck petroleum pipe fitting as claimed in claim 1, it is characterized in that: the internal surface of described interior tube body arranges one deck anticorrosive coat.
3. a kind of dismountable double-deck petroleum pipe fitting as claimed in claim 1, is characterized in that: outer surface parcel one deck glass wool thermal insulation separation thermosphere of described interior tube body.
