Abstract
The invention discloses a composite corrosion prevention pipe provided with metal thread buckles, which comprises a pipe body, wherein iron-aluminum multicomponent alloy layers are coated on the inner wall and the outer wall of the pipe body, pure alloy layers are arranged on arc surfaces of the iron-aluminum multicomponent alloy layers, which are far away from the pipe body; and outer walls at two ends of the pipe body are provided with metal short sections, and the thread buckles are arranged on the metal short sections. The composite corrosion prevention pipe has the advantages of better corrosion resistance performance, large bonding force, good mechanical property and ageing resistance, and better wax scale prevention effect, and solves the problem of difficulty in corrosion prevention of the thread buckles of the corrosion prevention pipe of an oil field.
Description
Technical field:
The present invention relates to oil recovery field, oil field used a kind of oil pipe or sleeve pipe, belong to the heavy anti-corrosion pipe of a kind of stainless steel.
Background technique:
Adopt oil pipe or sleeve pipe to come liquid is transported during oil recovery, burn into perforation phenomenon can appear in the use for a long time of oil pipe or sleeve pipe, causes oil pipe or sleeve pipe not to reach and promptly can not re-use service life.And on-the-spot present applied oil pipe or casing tube anti-corrosive method are surperficial separation layer method, can only play the effect of temporary transient isolation environment aggressive medium, along with the prolongation of service time; Anticorrosive coat then begins the gas-bearing formation obscission to occur, causes tubing and casing corrosion aggravation, and surperficial separation layer is mainly the epoxy resin type coating simultaneously; These epoxy resin type coatings exist water absorption rate high, and anti-mechanical shock, anti-machinery scratch the problem of poor performance, and 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 are poor, cause tubing and casing wax deposition, scale formation 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 present invention provides a kind of composite anti-corrosive pipe that is provided with metal threaded button that is used for oil gas field; This anti-corrosion pipe not only has excellent corrosion resisting performance, big, the good mechanical property, anti-aging of combination force; But also have the advantage of strong wax-proof anti-scaling, solved the problem of the anticorrosion difficulty of oil gas field anti-corrosion pipe screw buckle simultaneously.
The technological scheme that the present invention taked is: the composite anti-corrosive pipe that is provided with metal threaded button; Comprise tube body; 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 tube body two ends outer wall is provided with the metal pipe nipple, and described metal pipe nipple is provided with screw buckle.
Described metal pipe nipple is the stainless steel pipe nipple.
The inside and outside nanometer polymer coating that also is provided with of described pure alloy-layer.
The invention has the beneficial effects as follows: the multicomponent alloy layer of this composite anti-corrosive pipe has the stainless steel characteristic, and form metallurgical chemistry between coating or plating layer and combine, strong adhesion, and have the anode loss protection effect, have higher mechanical strength and corrosion resistance; Described tube body two ends outer wall is provided with the metal pipe nipple, and described metal pipe nipple is provided with screw buckle, has solved the anticorrosion difficult problem of the oil casing threaded button in oil field; Simultaneously, the composite anti-corrosive pipe of stainless steel is purified again, carry out nanometer and gather the coating rotary spraying, this composite anti-corrosive tube-surface light, smooth, free of pinholes, non-scaling, 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.
