Abstract

The utility model discloses a chloroprene rubber anti-corrosion tube for ocean engineering, which comprises a steel inner tube, a chloroprene rubber anti-corrosion layer coats the external surface of the steel inner tube, a marine growth preventing layer coats the chloroprene rubber anti-corrosion layer, the marine growth preventing layer is a chloroprene rubber coating, and a copper-nickel alloy particle is exposed on the surface thereof. The section diameter of the copper-nickel alloy particle is 1mm, the length is 1mm, and the resistance is 3-5 megohm. The utility model overcomes defects of the prior art, has reasonable structure and simple making, and can prevent adhesion and breeding of marine life of stand pipes of ocean engineering splash zones, and can further prevent microbial corrosion caused thereby.

Description

Ocean engineering neoprene anti-corrosion pipe
Technical field
The utility model relates to the seabed engineering pipeline, specifically, relates to the anti-marine growth corrosion pipeline that a kind of ocean engineering is used.
Background technique
Marine fouling organism or title marine attaching organism are animal, plant and the microorganisms that is grown in hull bottom and Offshore Units surface; Because they adhere to and to all harm that facility caused, are referred to as sea marine organism pollution.Marine growth promotes corrosion and causes crevice corrosion, increases the sectional area of marine building pile, post, strengthens the impact force of wave and ocean current, blocking pipe etc.Therefore, human since the development and use marine resources, by adhering to caused stained problem, marine growth perplexed always.
Standpipe in the ocean engineering pipe-line, especially splash zone standpipe adopt three-layer polyethylene anticorrosive coat, high solid epoxy coating to carry out anticorrosion usually.But above-mentioned coating surface is often adhered to, multiplies by marine growth, causes microbiologic(al) corrosion, destroys anticorrosion coating on pipeline and steel pipe.Three-layer polyethylene anticorrosive coat, high solid epoxy coating can not prevent effectively that marine growth from adhering to, multiplying problem, can not fundamentally solve pipeline microbiologic(al) corrosion problem.
The model utility content
The technical problems to be solved in the utility model is to overcome aforementioned deficiency of the prior art, provide a kind of rational in infrastructure, make simple ocean engineering neoprene anti-corrosion pipe, can prevent that ocean engineering splash zone standpipe from adhering to, multiplying because of marine growth, and then prevent its caused microbiologic(al) corrosion.
In order to solve the problems of the technologies described above, the utility model is achieved by following technological scheme:
A kind of ocean engineering neoprene anti-corrosion pipe, comprise pipe in the steel, described steel inner tube outer surface is coated with the neoprene anticorrosive coat, described neoprene anticorrosive coat outer surface is coated with anti-marine growth adhesive layer, described anti-marine growth adhesive layer is a neoprene coating, and surface exposure has the copper-nickel alloy particle.
The diameter of section of described copper-nickel alloy particle is 1mm, and length is 1mm.
The resistance of described copper-nickel alloy particle surface is 3~5M Ω.
The beneficial effects of the utility model are:
Because anti-marine growth adhering coating of the present utility model has the copper-nickel alloy particle, when copper-nickel alloy is corroded, can discharge poisonous copper ion, can stop marine organisms to adhere to reproduction at coating surface, thereby make coating avoid further corrosion, and then prevent that the marine growth etching problem from taking place.
Description of drawings
Fig. 1 is a horizontal section schematic representation of the present utility model;
Fig. 2 is a longitudinal profile schematic representation of the present utility model.
Among the figure: pipe in the steel---1, the neoprene anticorrosive coat---2, anti-marine growth adhesive layer---3.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model is a kind of ocean engineering neoprene anti-corrosion pipe, comprise pipe 1 in the steel, pipe 1 outer surface is coated with neoprene anticorrosive coat 2 in the described steel, described neoprene anticorrosive coat 2 outer surfaces are coated with anti-marine growth adhesive layer 3, described anti-marine growth adhesive layer 3 is a neoprene coating, and its surface exposure has the copper-nickel alloy particle.
Wherein, described copper-nickel alloy particle is according to weight portion, and the Ni by 10%, 2% Fe and 88% Cu form.
Described copper-nickel alloy particle can be approximated to be cylindrical body, and its size is that diameter of section is 1mm, and length is 1mm.
The area that described copper-nickel alloy particle is exposed to the neoprene coating surface is not less than 30%, and the copper-nickel alloy particle bare area in the present embodiment is 40%.
The resistance of described copper-nickel alloy particle surface is 3~5M Ω, and the resistance of the copper-nickel alloy particle surface in the present embodiment is 3.6M Ω.
Method for prefabricating of the present utility model is:
Pipe 1 surface is through rust cleaning, cleaning in the steel, form neoprene anticorrosive coat 2 at the certain thickness neoprene film of its outer surface parcel bonding, wrap up the certain thickness neoprene film that has the copper-nickel alloy particle of bonding then again in neoprene anticorrosive coat 2 outsides, form anti-marine growth adhesive layer 3, by vulcanization plant coating is vulcanized at last, promptly formed ocean engineering of the present utility model neoprene anti-corrosion pipe.
Below in conjunction with the accompanying drawings and embodiments the utility model is schematically described, this description does not have restricted.Those skilled in the art will be understood that in actual applications the constituted mode of neoprene anticorrosive coat 2 described in the utility model and anti-marine growth adhering coating 3 and combination each other all some change may take place as the case may be; And under enlightenment of the present utility model, other staff also may make the design similar to the utility model.Special needs to be pointed out is that only otherwise break away from design aim of the present utility model, all conspicuous changes and have the similar Design that is equal to replacement all should belong to protection domain of the present utility model.
