Abstract
The invention discloses a galvanized iron pipe which comprises an iron pipe body, a zinc-aluminum coating layer on the outer surface of the iron pipe body and a zinc-nickel coating layer on the inner surface of the iron pipe body. The iron pipe body is made of stainless steel. Both ends of the galvanized iron pipe are respectively provided with threads. The weight percents of zinc and aluminum in the zinc-aluminum coating layer are 54% to 65% and 35% to 46%. The weight percents of zinc and nickel in the zinc-nickel coating layer are88% to 94% and 6% to 12%. The galvanized iron pipe is silvery white and smooth in appearance, and both the zinc-aluminum coating layer on the outer surface of the galvanized iron pipe and the zinc-nickel coating layer on the inner surface of the galvanized iron pipe have good corrosion resistance, is not prone to causing friction losses, and can effectively protect the iron pipe body from being corroded to enable the galvanized iron pipe to have a long service life.
Description
Technical field
The present invention relates to a kind of ornament material, be specifically related to a kind of galvanized iron conduit.
Background technique
Existing aluminium-plastic plate iron pipe all adopts plating lacquer to protect mostly on the current market, but lacquer is easily by frictional loss, thereby causes inner iron pipe to be corroded, and shortens iron pipe working life.
Summary of the invention
The object of the present invention is to provide a kind of galvanized iron conduit of firm, corrosion-resistant, long service life.
Technological scheme of the present invention is, a kind of galvanized iron conduit, comprise the zinc-aluminium coating of iron pipe body, this external surface of iron pipe and the Zinc-Nickel coating layer of iron pipe body internal surface, described iron pipe body is made of stainless steel, described galvanized iron conduit two ends have been respectively arranged with screw thread, zinc and the shared weight percentage of aluminium are respectively 54%-65% and 35%-46% in the described zinc-aluminium coating, and the shared weight percentage of zinc and nickel is respectively 88%-94% and 6%-12% in the described Zinc-Nickel coating layer.
In a preferred embodiment of the present invention, zinc and the shared weight percentage of aluminium are respectively 58% and 42% in the described zinc-aluminium coating.
In a preferred embodiment of the present invention, zinc and the shared weight percentage of aluminium are respectively 62% and 38% in the described zinc-aluminium coating.
In a preferred embodiment of the present invention, the shared weight percentage of zinc and nickel is respectively 92% and 8% in the described Zinc-Nickel coating layer.
In a preferred embodiment of the present invention, the shared weight percentage of zinc and nickel is respectively 89% and 11% in the described Zinc-Nickel coating layer.
In a preferred embodiment of the present invention, the thickness of described zinc-aluminium coating is 1.2mm-1.6mm, and the thickness of described iron pipe body is 1.9mm-2.4mm, and the thickness of described Zinc-Nickel coating layer is 0.4mm-0.7mm.
Of the present invention is a kind of galvanized iron conduit; this galvanized iron conduit smooth in appearance, be silvery white in color; the zinc-aluminium coating of outer surface and the Zinc-Nickel coating layer of internal surface all have fabulous corrosion resistance; and be not easy to cause friction loss; can effectively protect the iron pipe body not weather, make the galvanized iron conduit longer service life.
Description of drawings
Fig. 1 is the structural representation in galvanized iron conduit one preferred embodiment of the present invention;
Each mark is as follows in the accompanying drawing: 1, iron pipe body, 2, zinc-aluminium coating, 3, Zinc-Nickel coating layer.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
Of the present invention is a kind of galvanized iron conduit, referring to shown in Figure 1, comprise the zinc-aluminium coating of iron pipe body, this external surface of iron pipe and the Zinc-Nickel coating layer of iron pipe body internal surface, described iron pipe body is made of stainless steel, described galvanized iron conduit two ends have been respectively arranged with screw thread, zinc and the shared weight percentage of aluminium are respectively 54%-65% and 35%-46% in the described zinc-aluminium coating, and the shared weight percentage of zinc and nickel is respectively 88%-94% and 6%-12% in the described Zinc-Nickel coating layer.
In a preferred embodiment of the present invention, zinc and the shared weight percentage of aluminium are respectively 58% and 42% in the described zinc-aluminium coating.
Further, zinc and the shared weight percentage of aluminium are respectively 62% and 38% in the described zinc-aluminium coating.
Further, zinc and the shared weight percentage of nickel are respectively 92% and 8% in the described Zinc-Nickel coating layer.
Further, zinc and the shared weight percentage of nickel are respectively 89% and 11% in the described Zinc-Nickel coating layer.
Further, the thickness of described zinc-aluminium coating is 1.2mm-1.6mm, and the thickness of described iron pipe body is 1.9mm-2.4mm, and the thickness of described Zinc-Nickel coating layer is 0.4mm-0.7mm.
Of the present invention is a kind of galvanized iron conduit; this galvanized iron conduit smooth in appearance, be silvery white in color; the zinc-aluminium coating of outer surface and the Zinc-Nickel coating layer of internal surface all have fabulous corrosion resistance; and be not easy to cause friction loss; can effectively protect the iron pipe body not weather, make the galvanized iron conduit longer service life.
The above only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
