The utility model discloses a nano-coated anti-corrosion pipe, which comprises a pipe body, an iron-aluminum multi-element alloy layer and a pure alloy layer. The arc surface away from the pipe body is provided with a pure alloy layer, and the pure alloy layer is also provided with a nanometer polymer coating as the inner or outer wall of the anti-corrosion pipe. The anti-corrosion pipe not only has good corrosion resistance, strong binding force, good mechanical properties, anti-aging, but also has the advantages of strong anti-wax and anti-scaling.
Description
Technical field:
The utility model relates to oil recovery field, oil field used a kind of oil pipe or sleeve pipe, belongs to a kind of nanometer coating pipe that is used for oil gas field.
Background technique:
Adopt oil pipe or sleeve pipe to come liquid is transported during oil recovery, oil pipe or sleeve pipe burn into perforation phenomenon can occur in long-term use, cause oil pipe or sleeve pipe not to reach and promptly can not re-use service life.And on-the-spot present applied tubing and casing anti-corrosion method is surperficial separation layer method, can only play the effect of temporary transient isolation environment aggressive medium, prolongation along with service time, anticorrosive coat then begins to occur the gas-bearing formation obscission, cause the aggravation of oil pipe or casing corrosion, surperficial separation layer is mainly the epoxy resin type coating simultaneously, there is the water absorption rate height in these epoxy resin type coatings, anti-mechanical shock, anti-machinery scratches the problem of poor performance, anticorrosive coat can damage when construction and carrying, have a strong impact on antiseptic effect, reduced the working life of oil pipe, and the wax control of these separation layers, anti-scaling property is poor, causes the tubing and casing wax deposition, scale formation is serious, shorten the maintenance interval of tubing and casing, cause suitable economic loss.
Summary of the invention:
In order to overcome short deficiency of existing oil pipe or casing tube anti-corrosive, wax control, antiscaling effect difference and working life, the utility model provides a kind of nano coating anti-corrosion pipe, this anti-corrosion pipe not only has excellent corrosion resisting performance, big, the good mechanical property, anti-aging of combination force, but also has the advantage of strong wax-proof anti-scaling.
Technical solution adopted in the utility model is: the nano coating anti-corrosion pipe, comprise tube body, iron aluminium multicomponent alloy layer, pure alloy-layer, described tube body inside and outside wall is coated with iron aluminium multicomponent alloy layer, described iron aluminium multicomponent alloy layer is provided with pure alloy-layer away from the arc surface of tube body, and described pure alloy-layer also is provided with the nanometer polymer coating as the inwall or the outer wall of anti-corrosion pipe.
The thickness of described nanometer polymer coating is 90～120 μ m.
The beneficial effects of the utility model are: the multicomponent alloy layer of this nano coating anti-corrosion pipe has the stainless steel characteristic, forms the metallurgical chemistry combination between coating or plating layer, strong adhesion, and have the anode loss protection effect, have higher mechanical strength and corrosion resistance; Simultaneously, anti-corrosion pipe is purified again, carry out the poly-coating rotary spraying of nanometer; This tube surfaces light, smooth, free of pinholes, non-scaling, not sticking oil; But dielectric corrosions such as acid-and base-resisting, salt, surface active agent, sewage, rock gas, microorganism; Have anticorrosion, antiscale, wax control and anti-delamination four anti-characteristics.
