Description
Technical field
The utility model is related to a kind of stainless steel pipes, more specifically, it relates to a kind of corrosion-proof steel pipe.
Background technology
Steel pipe is a large amount of conveyings for being used as fluid, the manufacture of machine components and engineering structure, with higher intensity
Lighter weight is a kind of very ideal tubing.
Steel pipe can be divided into two major classes by production method：Seamless steel pipe and seamed steel pipe, seamed steel pipe are referred to as steel pipes with straight.
Seamless steel pipe can be divided by production method：Hot seamless tube, drawn tube, precision tube, hot-expanding pipe, cold spinning pipe and extruded tube
Deng.Seamless steel pipe is made of Fine Steel Casting iron or steel alloy, there is hot rolling, cold rolling（It pulls out）Point.Seamless steel pipe can be used for various rows
The liquid air-pressure duct of industry and gas pipeline etc..Welded pipe line can be used for aqueduct, gas piping, caliduct, electric appliance pipe
Road etc..
Since the application field of steel pipe is various, keep the application environment faced also sufficiently complex, steel pipe can face strong rotten often
The application environment of corrosion.Existing steel pipe corrosion resistance is poor, is not applied in corrosive environment, and make steel pipe applies model
It encloses and is subject to certain restrictions.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of corrosion-proof steel pipe, have
Good corrosion resistance can use in some corrosive environments.
To achieve the above object, the utility model provides following technical solution：
A kind of corrosion-proof steel pipe, including tube body, are provided with epoxy resin layer on the inner wall of the tube body, the tube body it is outer
By introversion to be disposed with the first zinc layers and zirconium oxide layer on wall.
Preferably：Matcoveredn is arranged in the inside of the epoxy resin layer.
Preferably：The second zinc layers are provided between the epoxy resin layer and the inner wall of tube body.
Preferably：The protective layer is polyethylene layer.
Preferably：The inner and outer wall of the tube body is frosting.
Preferably：The thickness of the zirconium oxide layer is 0.05-0.1mm.
Preferably：The thickness of the epoxy resin layer is 0.2-0.5mm.
Compared with prior art, the utility model has the advantages that：The steel pipe, by the way that one layer of ring is arranged on the inner wall of tube body
Oxygen resin can make the inner surface of tube body have outstanding anti-corrosion since epoxy resin has good rotproofness and wear resistence
Corrosion energy and wear-resisting property, when the inner surface of tube body touches corrosive substance, epoxy resin is by corrosive substance and tube body
Isolation, and epoxy resin does not react with corrosive substance, thus can be well protected inboard wall of tube body.And by tube body
Outer wall on plate the first zinc layers, due to zinc have anti-oxidant and corrosion resistance, the outer wall of tube body can be played protection make
With in addition, be also coated with one layer of zirconium oxide outside the first zinc layers, zirconium oxide chemical property is stablized, and is insoluble in water, hydrochloric acid and dilute
Sulfuric acid, and its extreme hardness, the surface for being covered in the first zinc layers is first can be anticorrosive, and followed by zirconium oxide layer is not easy
Breakage plays a protective role to the first zinc layers, makes the first zinc layers be difficult to be scratched, is damaged, having ensured that the first zinc layers are normally sent out
Wave corrosion-resistant, antioxidation.Therefore the steel pipe has splendid corrosion resistance, can cope with a variety of application environments.

Specific implementation mode
Referring to Fig.1, a kind of corrosion-proof steel pipe, including tube body 1, are provided with epoxy resin layer 5 on the inner wall of tube body 1,
By introversion to be disposed with the first zinc layers 2 and zirconium oxide layer 3 on the outer wall of tube body 1.Here, the thickness of zirconium oxide layer 3 is
0.05-0.1mm, and the thickness of epoxy resin layer 5 is 0.2-0.5mm.
Since the application scenario of tube body 1 is more complicated, acid, the water etc. containing electrolyte or salt are often faced, these
Substance may be corroded after all there is corrosivity, steel pipe contacts for a long time with these substances, thus need to the inner wall of steel pipe with
Outer wall is all effectively protected, and corrosion resistant performance is made it have, to extend its service life.In the present embodiment, by
One layer of epoxy resin is set on the inner wall of tube body 1, since epoxy resin has good rotproofness and wear resistence, tube body can be made
1 inner surface has outstanding Corrosion Protection and wear-resisting property, when the inner surface of tube body 1 touches corrosive substance, ring
Oxygen resin completely cuts off corrosive substance and tube body 1, and epoxy resin does not react with corrosive substance, thus can protect well
Protect 1 inner wall of tube body.
And by plating the first zinc layers 2 on the outer wall of tube body 1, it, can be with since zinc has anti-oxidant and corrosion resistance
It plays a protective role to the outer wall of tube body 1, in addition, being also coated with one layer of zirconium oxide in the outside of the first zinc layers 2, zirconium oxide is chemically
Matter is stablized, and water, hydrochloric acid and dilute sulfuric acid, and its extreme hardness are insoluble in, and the surface for being covered in the first zinc layers 2 is first can be with
Anticorrosive, the followed by not cracky of zirconium oxide layer 3 plays a protective role to the first zinc layers 2, the first zinc layers 2 is made to be difficult to be scratched,
Breakage has ensured that the first zinc layers 2 normally play corrosion-resistant, antioxidation.
In addition, though epoxy resin layer 5 is more wear-resisting, but exposed, it is made directly to be contacted with corrosive substance, still
So it will appear the case where epoxy resin layer 5 is worn, it is therefore desirable to be protected to epoxy resin layer 5, to further increase steel
The corrosion resistance of pipe.In the present embodiment, it is also covered with layer protective layer on the surface of epoxy resin layer 5, which is poly- second
Alkene layer 6, polyethylene have very high wearability and intensity, and good protection can be played to epoxy resin layer 5, extend asphalt mixtures modified by epoxy resin
The service life of fat.
In addition, the second zinc layers 4 are also provided in the present embodiment between epoxy resin layer 5 and the inner wall of tube body 1.Due to
One zinc layers 2 and the second zinc layers 4 are all there is certain risk to fall off, to reduce the risk, here by the way of zinc-plated
The inner and outer wall of tube body 1 is processed into frosting, since frosting has the hole much smiled, can be made when zinc-plated
Zinc enters in hole, to increase the adhesive force of zinc layers, the first zinc layers 2 and the second zinc layers 4 is made more reliably to be attached to tube body 1
Surface reduces the risk to fall off.
The steel pipe has splendid corrosion resistance, can cope with a variety of application environments.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
