Description
Technical field
The utility model relate to a kind of resisting high temperature, high salt bittern corrosion adopt brine pipeline, belong to brine mining technical field.
Background technique
China has abundant subsurface brine resource, especially the underground deep layer bittern of the Huanghe delta, and salinity is very high, and wherein salinity is up to 32.5%, and the high temperature and high salt bittern that temperature reaches more than 80 DEG C has very large exploitation value.But the temperature of underground deep layer bittern and salinity are very high, easily cause the corrosion of adopting brine pipeline, thus constrain the high-efficiency mining of bittern.
The bittern of high temperature and high salt very easily corrodes adopts brine pipeline road, and pipeline is once seriously corroded, and sub-salt well will be destroyed, and needs again to dig a well, and will increase the cost of brine mining so greatly, and the high investment low yield of brine mining industry will be caused to go out phenomenon.Therefore, the etching problem paying much attention to adopt brine pipeline is needed.Research shows, for high temperature and high salt bittern, carbon steel piping has the etching extent of annual 2.0mm/yr (80 DEG C), if pipeline life is 10 years, so total etching extent is 20mm, so general carbon steel piping will be destroyed with less than 10 years; The Corrosion amount of 304 stainless steels (80 DEG C) is 0.66mm/yr, and total etching extent of 10 years is 6.6mm; The Corrosion amount of A3 carbon steel (Q235) 80 DEG C is 2.43mm/yr, and total etching extent of 10 years is 24.3mm; The Corrosion amount of N80 steel is 1.61mm/yr, and total etching extent of 10 years is 16.1mm.Above-mentioned data illustrate, use common carbon steel piping recovery of subterranean deep layer high temperature and high salt bittern, and along with the continuous increase of corrosion, tube wall is constantly thinning, sub-salt well will soon be made to become disused well, do not reach the requirement of high-efficiency and economic mining brine.If use the stainless steel that anti-corrosion capacity is stronger, although the requirement in pipeline working life can be met, calculate by the market price, the trend that cost can increase in many times.Claimant finds through experiment, in 80 DEG C of high bittern waters, the corrosion resistance of the N80 steel of surface attachment nickel tungsten phosphorus alloy-layer is better than Ordinary Steel and alloyed steel, even be better than stainless steel, brine pipeline is adopted for proposing the corrosion of a kind of resisting high temperature, high salt bittern, using N80 steel as adopting brine pipeline body material, adopting on brine pipeline body and bittern contact surface, be coated with the nickel tungsten phosphorus alloy-layer of resisting high temperature, high salt bittern corrosion, improving anti-corrosion capacity; The method not only can meet anticorrosive requirement, meets the time limit requirement of production tubing life-span, and cost of winning that is that cause increases problem because corroding discarded can also to reduce pipeline.
Model utility content
For the deficiencies in the prior art, what the utility model provided a kind of resisting high temperature, high salt bittern to corrode adopts brine pipeline.
The technical solution of the utility model is as follows:
The corrosion of resisting high temperature, high salt bittern adopt a brine pipeline, comprise and adopt brine pipeline body, described in adopt brine pipeline body surface on the anticorrosive coat of resisting high temperature, high salt bittern corrosion is set, described anticorrosive coat is nickel tungsten phosphorus alloy-layer.
Preferably, the body that brine pipeline body is N80 carbon steel material is adopted described in.
Preferably, the thickness of described nickel tungsten phosphorus alloy-layer is 0.1 ~ 0.3mm.
The beneficial effects of the utility model are:
The utility model is for the problem of adopting brine pipeline road in brine mining process and corroded by high temperature and high salt bittern, material and the structure in brine pipeline road is adopted by changing tradition, select erosion-resisting N80 plain steel as the novel body adopting brine pipeline, carry out plating anti-corrosion layer to adopting brine pipeline simultaneously, the corrosion that the defeated pipeline of defeated halogen effectively can resist high temperature and high salt bittern is adopted after this model utility, reduce high temperature and high salt bittern to the corrosion of adopting brine pipeline road, extend the working life of adopting brine pipeline road, improve the efficiency of brine mining.
