Abstract
The invention relates to an electroplated amorphous state nickel-based alloy corrosion-resistant wear-resistant oil pipe, and belongs to the field of oil field oil pipes. The inner surface of the oil pipe is electroplated with an amorphous state nickel-based alloy corrosion-resistant wear-resistant protection layer. The thickness of the protection layer is 20-50 microns. The protection layer is electroplated by the steps of oil removing, water washing, acid washing, water washing, activating, deionized water cleaning, electroplating, water washing and thermal treatment. Treatment is performed in oil removing liquid for 5-10 minutes; in acid washing, an oxide film is removed from a sulfur solution till the natural color of metal is exposed; in electroplating, nickel alloy electroplating liquid is adopted, the PH value is adjusted to 2-6 by using nickel carbonate, the temperature is more than or equal to 60 DEG C, the current density is 2-8 A/dm<2>, and the electroplating time is 2 hours; in thermal treatment, the temperature is kept at 200-300 DEG C for 1.5 hours. The oil pipe has the advantages of high microhardness, resistance to acid and alkali corrosion, high wear resistance and long service life.
Description
Technical field
The present invention relates to oil pipeline technical field, is a kind of electroplating amorphous nickel-base alloy anti-corrosive abrasion-proof oil conduit concretely.
Background technology
Because oil field at home exploitation is mostly to middle and later periods exploitation, development difficulty strengthens, and oil well surrounding medium constantly worsens, and in well liquid, contains CO
2, H
2the corrosive medium such as S and salt solution, also has the impurity such as sand grains, requires oil pipe to have higher hardness, the performance such as wear-resisting, anti-corrosion, thereby meet the on-the-spot needs that use at rugged environment like this.The main failure forms of oil pipe is abrasion and corrosion.
Current domestic tube inner wall treatment process is mainly chromium plating, nitrogenize etc.The domestic chrome-plating method that generally adopts at present, chrome-plating method acid and alkali-resistance and sulfide, not salt spray resistance, abrasion resistance is good, but Cr VI environmental pollution is serious.Nitrogenize is not acidproof, and abrasion resistance is general, and environment is also had to pollution.Along with the pay attention to day by day of country to environment, urgently a kind of new environment-protective process replaces the techniques such as chromium plating.
Summary of the invention
Object of the present invention is exactly the defect existing for prior art, and provide a kind of and there is good anticorrosive, fatigue behaviour and anti-wear performance, and manufacturing process electroplating amorphous nickel-base alloy anti-corrosive abrasion-proof oil conduit free from environmental pollution.
Its technical scheme is: be coated with the Ni-based alloy anticorrosion antiwear of one deck amorphous state overcoat at pipe inner surface.The thickness 20-50 μ m of this overcoat.The plating step of this overcoat is: oil removing-washing-pickling-washing-activation-washed with de-ionized water-plating-washing-heat treatment.In degreasing fluid, process 5-10 minute; Pickling is in sulfuric acid solution, to remove oxide film, until exposing metal true qualities; Plating is to adopt boron-tungsten-iron-nickel alloy electroplating, with nickelous carbonate tune pH value 2-6, temperature>=60 DEG C, current density 2-8A/dm
2, electroplating time is 1.5-2.5 hour; Heat treatment is to be incubated 1.5 hours under 200-300 DEG C of environment.
Described boron-tungsten-iron-nickel alloy electroplating is the raw material composition of pressing row w/v: main salt nickelous sulfate 300-500g/L, sodium tungstate 30-50g/L, and be equipped with boric acid 25-35 g/L as buffer, be equipped with complexing agent 15-25g/L.
Advantage of the present invention is: what the pipe inner surface overcoat of electroplating amorphous nickel-base alloy anti-corrosive abrasion-proof oil conduit adopted is amorphous state nickel alloy plating layer, has improved the application life of oil pipe.Because the Ni-based alloy layer of amorphous state has, long-range is unordered, shortrange order, compact structure, and isotropism, does not have crystal boundary, dislocation and defect, has that microhardness is high, acid-alkali-corrosive-resisting, abrasion resistance be good, and the feature good with base material adhesion.And this electroplating technology is a kind of clean production technology, only need slightly deal with the electroplating wastewater producing is reusable edible, and environmental protection treatment expense is little, does not pollute the environment.Oil pipe of the present invention has that microhardness is high, acid-alkali-corrosive-resisting, abrasion resistance are good, long service life.
