Abstract
The utility model relates to a steel pipe, especially a corrosion -resistant new material galvanized pipe, the steel pipe inner wall is equipped with first galvanizing coat, is the roughness that the steel pipe outer wall was equipped with through the hairization processing 0.1 3.2 the superficial layer of micron, the superficial layer surface is equipped with the second galvanizing coat, second galvanizing coat surface is equipped with the tin coating, the tin coating surface is equipped with the alloy -layer, the tin coating menstruation heat melt and handle to form the alloy -layer, fused tin can flow and fill and lead up the tin coating hole and slightly make not the plane surface and paste the surface of obeying at the second galvanizing coat for the outward appearance becomes polished bright, in addition tin -plating also further reinforceed the corrosion resistance of galvanized pipe, the utility model discloses a set up the roughness that the superficial layer improves the galvanizing coat, make the gloss of surface become polished bright through the tin coating, further improved corrosion resisting property moreover, do not adopt technologies such as plastic -coated, all can not produce noxious material and also can not warp and discolour even be used for accepting high -temperature steam or hot water.
Description
Technical field
This utility model relates to a kind of steel pipe, a kind of corrosion-resistant new material galvanized pipe.
Background technology
Existing galvanized pipe mostly have employed plastic-coated and strengthens corrosion resistance further, but the most increasingly ignores the improvement of galvanized pipe itself, can not use the field of plastics coated tube in part, and existing galvanized pipe (not carrying out the galvanized pipe of plastic-coated process) can not meet requirement.
Improved in the industry, such as Chinese patent discloses a kind of multi-functional galvanized pipe, application number: 201410093239.8, the applying date: 2014-03-14, it is coated with one layer of zinc on the inwall of described body and forms zinc coat, the thickness of described zinc coat is 10～15 microns, and described zinc coat is covered with passivating film.
The deficiency of technique scheme is that only making inwall processes, outer wall corrosion-resistant；Certainly also there is two sides inside and outside part galvanized pipe the most zinc-plated, but owing to the gloss of zinc coat itself is gloomy, more can form black and white speckle after life-time service on surface, affect outward appearance (the hot water heating coil pipe that such as Northern Part of China uses).
Summary of the invention
For the deficiencies in the prior art, this utility model provides a kind of corrosion-resistant and that glossiness is excellent galvanized pipe.
The technical solution of the utility model is:
nullA kind of corrosion-resistant new material galvanized pipe，Including steel pipe，It is characterized in that: described steel pipe inner wall is provided with the first zinc coat，The thickness of described first zinc coat is 300-500 gram every square metre，Described outer wall of steel pipe is provided with the surface layer that roughness is 0.1-3.2 micron through frosting treatment，Described surface layer outer surface is provided with the second zinc coat，The thickness of described second zinc coat is 400-500 gram every square metre，Described second zinc coat outer surface is provided with tin coating，The thickness of described tin coating is 2.8-3.5 gram every square metre，Described tin coating outer surface is provided with alloy-layer，Described tin coating forms alloy-layer through hot melt process，Melted stannum can flow and fills and leads up tin coating hole and slightly make uneven surface docile on the surface of the second zinc coat，Outward appearance is made to become polished bright，The most tin plating corrosion resistance also further enhancing galvanized pipe.
The beneficial effects of the utility model are: this utility model improves the flatness of zinc coat by arranging surface layer, the gloss of outer surface is made to become polished bright by tin coating, and further increase decay resistance, owing to not using the techniques such as plastic-coated, i.e. it is used in undertaking high-temperature steam or hot water all will not produce noxious substance and also will not deform variable color, be suitable for making high-end home hot-water heating coil pipe.

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further:
Embodiment 1
nullAs shown in Figure 1，A kind of corrosion-resistant new material galvanized pipe，Including the wherein side being shown that steel pipe in steel pipe 1(figure，The most schematically illustrate，Whole steel pipe is not drawn)，Described steel pipe 1 inwall is provided with the first zinc coat 2，The thickness of described first zinc coat 2 is 300 grams every square metre，Described steel pipe 1 outer wall is provided with the surface layer that roughness is 3.2 microns 3 through frosting treatment，Described surface layer 3 outer surface is provided with the second zinc coat 4，The thickness of described second zinc coat 4 is 400 grams every square metre，Described second zinc coat 4 outer surface is provided with tin coating 5，The thickness of described tin coating 5 is 2.8 grams every square metre，Described tin coating 5 outer surface is provided with alloy-layer 6，Described tin coating 5 forms alloy-layer 6 through hot melt process，Melted stannum can flow and fills and leads up tin coating 5 hole and slightly make uneven surface docile on the surface of the second zinc coat 4，Outward appearance is made to become polished bright，The most tin plating corrosion resistance also further enhancing galvanized pipe.
Embodiment 2
nullAs shown in Figure 1，A kind of corrosion-resistant new material galvanized pipe，Including steel pipe 1，Described steel pipe 1 inwall is provided with the first zinc coat 2，The thickness of described first zinc coat 2 is 400 grams every square metre，Described steel pipe 1 outer wall is provided with the surface layer that roughness is 0.1 micron 3 through frosting treatment，Described surface layer 3 outer surface is provided with the second zinc coat 4，The thickness of described second zinc coat 4 is 500 grams every square metre，Described second zinc coat 4 outer surface is provided with tin coating 5，The thickness of described tin coating 5 is 3.5 grams every square metre，Described tin coating 5 outer surface is provided with alloy-layer 6，Described tin coating 5 forms alloy-layer 6 through hot melt process，Melted stannum can flow and fills and leads up tin coating 5 hole and slightly make uneven surface docile on the surface of the second zinc coat 4，Outward appearance is made to become polished bright，The most tin plating corrosion resistance also further enhancing galvanized pipe.
