Abstract
The utility model provides an anticorrosive oil pipe of inner wall calorization, including the oil pipe base member, oil pipe base member inner wall is equipped with the calorization anticorrosive coating, and the calorization anticorrosive coating includes ferro -aluminium alloy layer and pure aluminium lamination. Utilize quick hot dipped aluminum technique on oil pipe internal surface formation metallurgical bonding's surface aluminizing layer, can prevent various corruption liquid, gaseous corruption to oil pipe in the well liquid effectively to reduce corrosion failure, reduce the cost for oil production, improve the production efficiency of oil well.
Description
Technical field
The utility model relates to technical field of oil extraction equipment, is specifically related to a kind of inwall aluminising antisepsis oil pipe.
Background technology
At present, oil production develops to ultra-deep, ultrahigh-temperature, ultra-high voltage direction gradually, and the Working environment of oil gas well is relatively more severe, causes oil production equipment to be subject to seriously corroded, causes the oil production equipment replacement cycle to shorten, thus cost for oil production is increased. Such as: in oil production equipment, the corrosion of oil pipe often causes oil well failure, producing well work is made normally to run. The corrosion of elimination and minimizing oil pipe becomes the major subjects of field of petroleum machinery research, the urgent needs that manufacture has better antiseptic property, the oil pipe of wear resisting property also becomes oil recovery industry.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of inwall aluminising antisepsis oil pipe, quick hot dipping aluminum technology is utilized to form the alitizing layer of metallurgical binding at pipe inner surface, can effectively prevent the various corrosive liquids in well liquid, gas to the corrosion of oil pipe, thus reduce corrosion failure, reduce cost for oil production, it is to increase the production efficiency of oil well.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of inwall aluminising antisepsis oil pipe, comprises oil pipe matrix, and described oil pipe matrix inwall is provided with aluminising preservative coat, and aluminising preservative coat comprises ferroalloy parts and aluminum layer.
As the further restriction of technique scheme, the thickness of described ferroalloy parts is 0.01mm～1mm, and aluminum layer thickness is 0.01mm～1mm.
The beneficial effects of the utility model are according to known to describing of such scheme:
Above-mentioned inwall aluminising antisepsis oil pipe utilizes quick hot dipping aluminum technology to form the alitizing layer of metallurgical binding at pipe inner surface, can effectively prevent the corrosive deposit in well liquid to the corrosion of oil pipe, thus reduce corrosion failure; Meanwhile, this aluminising preservative coat not only has excellent anti-corrosion, resistance toheat, also has higher wear resistance, and the production efficiency of reduction cost for oil production, raising oil well is had economic benefit and social benefit widely.
It thus is seen that the utility model compared with prior art, has substantive distinguishing features and progress.

Fig. 1 is structural representation of the present utility model;
In figure: 1, oil pipe matrix, 2, ferroalloy parts, 3, aluminum layer.
Embodiment
For clearly demonstrating technology feature of the present utility model, below by specific embodiment and by reference to the accompanying drawings the utility model scheme is described in detail.
The inwall aluminising antisepsis oil pipe that the utility model provides, comprises oil pipe matrix 1, and described oil pipe matrix 1 inwall is provided with aluminising preservative coat, and aluminising preservative coat comprises ferroalloy parts 2 and aluminum layer 3; Wherein, the thickness of described ferroalloy parts 2 is 0.01mm～1mm, and the thickness of aluminum layer 3 is 0.01mm～1mm.
Tube inner wall of the present utility model is covered with ferroalloy parts 2 and aluminum layer 3 double layer anticorrosive layer, aluminum layer 3 can form compact aluminum oxide film under corrosive medium, can corrosive medium be completely cut off outside steel matrix, reach the effect of protection against corrosion, and aluminum layer 3 has autoxidation repair ability, it is ensured that the integrity of pellumina; When aluminum layer 3 has consumed, ferroalloy parts 2 also can generate the compound of spinel structure in the process of oxidation, this kind of compound stacking density is big, without room, zero defect, not only can stop oxidation, and the atom stoping corrosive medium contacts with iron atom, corrosion product can not be formed, thus prevent tube corrosion.
In above-described embodiment, better embodiment of the present utility model is described, however, be evident that under invention of the present utility model is conceived, still can make a lot of change. At this, it should illustrate, any change made under invention of the present utility model is conceived all will fall in protection domain of the present utility model.
