Background
The steel pipe comprises a circular steel pipe body outside, an inner cavity is formed in the steel pipe body, and the steel pipe is generally applied to urban water delivery; in order to prevent the inner cavity and the outer surface of the steel pipe from being corroded, the technical scheme is that an anticorrosive layer is arranged inside and outside the steel pipe body, and the anticorrosive layer is an inner anticorrosive layer and an outer anticorrosive layer respectively; in the prior art, the anticorrosive coating is generally a material, for example, the anticorrosive coating is sprayed hot melt plastic, and the hot melt plastic has the advantage of low cost, but also has the defect of poor corrosion resistance; for another example, the corrosion-resistant layer is a zinciferous layer, which has a good corrosion resistance, but has a disadvantage of high cost. Can not meet the requirements of low cost and good corrosion resistance.
Disclosure of Invention
The purpose of the utility model is to provide a steel pipe with zinc impregnation layer at the end, which has low cost and good corrosion resistance.
The purpose of the utility model is realized like this: the steel pipe with the end part provided with the zincizing layer comprises a round steel pipe body outside, wherein an inner cavity is formed inside the steel pipe body, and an anticorrosive layer, namely an inner anticorrosive layer and an outer anticorrosive layer, is arranged inside and outside the inner cavity of the steel pipe body; the method is characterized in that: the steel pipe comprises a steel pipe body and is characterized in that inner zinc-infiltrated layers are arranged on the inner sides of the end parts at the two ends of the steel pipe body, outer zinc-infiltrated layers are arranged on the outer sides of the end parts at the two ends of the steel pipe body, an inner hot-melt plastic layer is arranged in the middle of the inner side of the steel pipe body, and an outer hot-melt plastic layer is arranged on the outer side of the.
Furthermore, the inner cavity of the steel pipe body is provided with a diameter expanding part, the inner hot-melt plastic layer is arranged in the diameter expanding part, and the inner hot-melt plastic layer and the inner zinc-infiltrated layer are arranged on the same plane.
Furthermore, the middle of the outer side of the steel pipe body is provided with a contraction ring, the outer hot melt plastic layer is arranged in the contraction ring, and the outer surface of the outer hot melt plastic layer and the outer zinc-infiltrated layer are arranged on the same plane.
The utility model has the advantages that: such steel pipe has with low costs, the effectual advantage of anticorrosion.
Drawings
Fig. 1 is a schematic cross-sectional view of the present invention.
Fig. 2 is an enlarged view of a portion a in fig. 1.
Wherein: 1. the steel pipe comprises a steel pipe body 2, an inner cavity 3, an inner zinc-infiltrated layer 4, an outer zinc-infiltrated layer 5, an inner hot melt plastic layer 6, an outer hot melt plastic layer 7, a diameter expanding part 8 and a contraction ring.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the steel pipe with the zincizing layer at the end comprises a round steel pipe body 1 outside, wherein an inner cavity 2 is arranged inside the steel pipe body, and an anticorrosive layer, namely an inner anticorrosive layer and an outer anticorrosive layer, is arranged inside and outside the steel pipe body; the method is characterized in that: the steel pipe is characterized in that inner zinc-infiltrated layers 3 are arranged on the inner sides of the end parts at the two ends of the steel pipe body, outer zinc-infiltrated layers 4 are arranged on the outer sides of the end parts at the two ends of the steel pipe body, an inner hot-melt plastic layer 5 is arranged in the middle of the inner side of the steel pipe body, and an outer hot-melt plastic layer 6 is arranged on the outer side of the middle of the steel pipe body.
The utility model discloses having taken the zincizing layer with the both ends of steel pipe body, having good anticorrosive effect, having taken hot melt plastic layer with inboard and the outside in the middle of the steel pipe body, having advantage with low costs, because the both ends of steel pipe body often damage because anticorrosive not good, the utility model discloses setting up like this, having reduced two sections anticorrosive poor, and the phenomenon that other places also can not use can reach the same life-span in each position of steel pipe basically, can also reduce cost, realize the utility model aims at.
Furthermore, the inner cavity of the steel pipe body is provided with an expanding part 7, the inner hot-melt plastic layer is arranged in the expanding part, and the inner hot-melt plastic layer and the inner zinc-infiltrated layer are arranged on the same plane.
The utility model discloses set up like this and guaranteed the smoothness nature that the inner chamber was carried, also more can guarantee the steadiness of interior hot-melt plastics.
Furthermore, the middle of the outer side of the steel pipe body is provided with a contraction ring 8, the outer hot-melt plastic layer is arranged in the contraction ring, and the outer surface of the outer hot-melt plastic layer and the outer zinc-infiltrated layer are arranged on the same plane.
The utility model discloses set up like this and guarantee outer hot melt plastics's steadiness.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
