Abstract
The utility model provides a tungsten alloy gathers anticorrosive oil oil pipe of fluorine. Its technical scheme does: be equipped with in the outside of oil pipe base member (1) and gather the high temperature resistant anticorrosion coating of fluorine (2), be equipped with tungsten alloy anticorrosive coating (3) in the inside of oil pipe base member (1). Gathering the high temperature resistant anticorrosion coating of fluorine (2) thickness and being 120 mu m, tungsten alloy anticorrosive coating (3) thickness is 50 mu m. The utility model discloses two kinds of anticorrosive coatings of inside and outside wall have good ageing resistance can, long service life, cost are import oil pipe's about 25%, have effectively reduced the cost for oil production, it is smooth that the outer wall gathers the high temperature resistant coating surface of fluorine, cohesion and adhesion reinforce at oil pipe hookup in -process, can not lose no time etc. Because of the breakout tongs and the defect appears, it is anticorrosive to form no dead angle, environmental protection in the production process is pollution -free, for green production technology.
Description
Technical field
The utility model relates to technical field of anticorrosion, and especially tungsten alloy gathers the anticorrosion petroleum oil of fluorine.
Background technique
In oilfield process, corrosion is ubiquitous a kind of natural phenomenon, and corrosion not only causes serious harm to field produces, oil field is suffered huge economic loss, also result in simultaneously in various degree environmental pollution.Especially, in the development process of offshore oil production, the inside and outside wall corrosion of oil field pipe is the huge difficult problem that ocean development faces.The oil pipe inside and outside wall of field use all has an antiseptic property and the good tubing of anticorrosion ability is generally the corrosion-proof type oil pipe of the 13Cr of external import, this oil pipe tubing cost be the 8-10 of plain tubing doubly.
Summary of the invention
The utility model is for above-mentioned deficiency, and propose a kind of practicality rational in infrastructure, safe and reliable, equipment cost is low, and the tungsten alloy of favorable anti-corrosion effect gathers the anticorrosion petroleum oil of fluorine.
The technical scheme in the invention for solving the above technical problem is: be provided with poly-fluorine high-temperature resistant anti-corrosive coating in the outside of oil pipe matrix, be provided with tungsten alloy anticorrosive coat in the inside of oil pipe matrix.Poly-fluorine high-temperature resistant anti-corrosive coating thickness is 120 μm, and tungsten alloy anticorrosive coat thickness is 50 μm.
Compared with prior art, the utility model has the advantage of: (1), in heatproof, all can reach 240 DEG C, heat resistance is excellent, can carry out normal service in high temperature environments; (2), two kinds of anticorrosive coats of inside and outside wall have good aging quality resistance, long service life; (3), cost is about 25% of import oil pipe, effectively reduces cost for oil production; (4), outer wall gathers fluorine high-temperature coating smooth surface, combination force and adhesive force strong, in oil pipe connection process, can not to tighten etc. because of pipe wrench and occur defect, be formed anticorrosion without dead angle; (5), environmental protection in production process, pollution-free, be green production process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, tungsten alloy gathers the anticorrosion petroleum oil of fluorine, forms primarily of oil pipe matrix 1, poly-fluorine high-temperature resistant anti-corrosive coating 2 and tungsten alloy anticorrosive coat 3; Be provided with poly-fluorine high-temperature resistant anti-corrosive coating 2 in the outside of oil pipe matrix 1, be provided with tungsten alloy anticorrosive coat 3 in the inside of oil pipe matrix 1.
The utility model technological process: oil-pipe external wall carries out high temperature oil removing, tube inner wall eliminates rust, and air-dry process before plating, then carries out the preservative treatment of tube inner wall tungsten alloy, and being coated with tungsten alloy anticorrosive coat thickness is 50 μm, then dries up and oil pipe hot process through liquid in pipe.Oil-pipe external wall gathers the preservative treatment of fluorine high-temperature coating, and it is 120 μm that outer wall is coated with poly-fluorine high-temperature resistant anti-corrosive coating thickness, then carries out cooling process in the insulation of 380 DEG C, oil pipe and oil pipe water, guarantees the excellent properties of inside and outside wall coating.
Claims (3)
