Abstract
The utility model relates to a tungsten plating non-crystalline alloy corrosion resistant oil pipe, which is a tubular body, and a tungsten-base non crystalline alloy protective layer is coated on the inner wall of the tubular body. The tungsten plated non crystalline alloy has the advantages that the tungsten plated non crystalline alloy has the structure of long range disorder and short range order, has compact structure is, the isotropy, and has no crystal boundary, dislocation and default, has high microhardness, good wearlessness, resists the corrosion of acid and alkaline, and has good binding force with base material. Furthermore, hexavalent chrome dose not exist during the electroplating process of the tungsten plated non crystalline alloy, nickel salt and tungsten salt mainly exist, and only ammonia gas is required to be slightly processed during the electroplating process, therefore the environmental protection treatment cost is small, and no environmental problems produce during the process, and therefore, the utility model has good anticorrosion property and wear resistant property, improves the service life of the oil pipe, and does not pollute the environment during the production process.
Description
Technical field
The utility model relates to the sucker rod pump oil recovery machiner, refers to a kind of tungsten-plated amorphous alloy antisepsis oil pipe especially.
Background technology
Sucker rod pumping equipment is the oil production equipment of extensive use both at home and abroad, sucker-rod pumping system is made up of oil pumper, R a T, oil pipe is one of critical component of sucker rod pumping equipment, be the oil-water well mode of production important component part, be that oil-water well is adopted the passage of annotating medium, often contain CO in the working media
2, H
2Corrosive medium such as S and salt solution along with the prolongation of service time, must corrode.
Aborning, it is the oil well pump transferring power that sucker rod moves back and forth constantly in oil pipe, it uses length to be generally about a km, reach about 0.5 meter than tubing string is flexible, add the straightness accuracy Accumulated deviation of the less and tubing string of oil pipe endoporus, certainly will cause periodically (frequency is with the oil pumper jig frequency) impact sticking friction tube inner wall of sucker rod, the scene is referred to as eccentric wear.
More than two kinds of factors often in oil well, exist simultaneously, add that the field produces measure injects stratum and the intrinsic polymer in stratum, corrosion inhibiter, organic acid and early flooding bring increasing mineralizer (Ca
2+, Mg
2+, CL-, HCO
3 -, SO
4 2-), reservoir sand or the like, abominable oil well environment cause tube inner wall will bear adhesive wear (containing erosive wear), abrasive wear and oxidative wear.Serious oil well pipe causes relevant perforation in short some months, the tubing string cost is increased, and directly affects crude oil production simultaneously again.The main failure forms of oil pipe is wearing and tearing and corrosion.
Summary of the invention
The purpose of this utility model provides a kind of tungsten-plated amorphous alloy antisepsis oil pipe, and it has good corrosion resistance and anti-wear performance, thereby has improved the application life of oil pipe.
For achieving the above object, the utility model is taked following design scheme:
A kind of tungsten-plated amorphous alloy antisepsis oil pipe is tubular body, it is characterized in that, described tubular body inwall is coated with the tungsten based amorphous attitude alloy protective of one deck layer.
Overcoat thickness is 20 μ m-50 μ m.
The utility model has the advantages that: the utility model tungsten-plated amorphous alloy antisepsis oil pipe, its tubular body inwall are coated with the tungsten based amorphous attitude alloy protective of one deck layer.Tungsten based amorphous attitude alloy has that long-range is unordered, the structure of shortrange order, compact structure, and isotropism does not have crystal boundary, dislocation and defective, has microhardness height, good, the acid-alkali-corrosive-resisting of abrasion resistance, and the characteristics good with the base material adhesion.In addition, non-hexavalent chromium in the electroplating process of tungsten based amorphous attitude alloy mainly is nickel salt and tungsten salt, as long as the ammonia that produces in the electroplating process is dealt with slightly, therefore, the environmental protection treatment expense is little, does not have problem of environmental pollution.Therefore the utility model oil pipe has good corrosion resistance and anti-wear performance, improved the application life of oil pipe, and manufacturing process is free from environmental pollution.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
As shown in Figure 1, the utility model tungsten-plated amorphous alloy antisepsis oil pipe for tubular body 1, is characterized in that, tubular body 1 inwall is coated with the tungsten based amorphous attitude alloy protective of one deck layer 2.Tungsten based amorphous attitude alloy is YC-3 alloy or YC-4 alloy or the YC-520 alloy that Changsha New ﹠ High Technology Industry Development Zone Yingcai Science Co., Ltd produces.
The YC-3 alloy is made up of the Ni of W, the 30 weight % of 40 weight % and the Co of 30 weight %.
The YC-4 alloy is made up of the Ni of W, the 40 weight % of 40 weight % and the Fe of 20 weight %.
The YC-520 alloy by: the Ni of the W of 4-8 weight %, 80-90 weight % and the P of 3-14 weight % form.
The electroplating technology flow process of tungsten based amorphous attitude alloy: oil removing-clear water cleaning-etching (removing oxide film, the exposing metal true qualities)-clear water cleaning-plating-clear water cleans-dries up-heat treatment.
Overcoat 2 thickness are 20 μ m-50 μ m.
Claims (2)
1. a tungsten-plated amorphous alloy antisepsis oil pipe is tubular body, it is characterized in that, described tubular body inwall is coated with the tungsten based amorphous attitude alloy protective of one deck layer.
2. tungsten-plated amorphous alloy antisepsis oil pipe according to claim 1 is characterized in that: overcoat thickness is 20 μ m-50 μ m.
