Abstract

The utility model relates to a single-surface zinc-plated pipe which comprises a basal body and a zinc-plated layer, wherein the basal body is a steel pipe body, and the zinc-plated layer is a zincic material layer which is formed by that a zincic material is attached to the surface of the basal body. The utility model is characterized in that the zinc-plated layer is only formed on the peripheral surface of the basal body. The utility model effectively improves the range of application of the zinc-plated pipe and reduces the degree of difficulty in repairing a pipeline system.

Description

The one side zinc coating pipe

Technical field

The utility model relates to metal pipe material, relate in particular to a kind of one side zinc coating pipe of making pipe-line system applicable to assembly, it only forms zinc coat in the single face of tubular matrix, and is improved the range of application of galvanized pipe, and reduces the degree difficult in maintenance of the pipe-line system of its assembly manufacturing.

Background technology

The pipe-line system that general chemical substance utilizes the metal tube assembly to form more is carried, be beneficial to the storage or the processing of material, for asking the pipe-line system can be in adverse circumstances (as the coastal area, high salt region-by-region etc.) the medium-term and long-term use, be not subjected to such environmental effects to produce corrosion, many utilizations have corrosion proof pipe fitting assembly and make pipe-line system, in various anti-corrosion pipe fittings, has cheap advantage with galvanized pipe again, and be widely used, utilize the anti-corrosion characteristic of galvanized pipe plating zinc on surface layer, avoid the salinity in the environment, its surface of moisture attacks, nationality is to prolong the service life of pipe-line system.

Galvanized pipe generally is as matrix with steel pipe fittings, this matrix is carried out operations such as degreasing, washing, pickling, cosolvent and remove the impurity such as grease, spot and corrosion on surface, could electroplate this matrix, make the zinc material be attached to this matrix surface and form zinc coat, last removing through washing again residues in surperficial electrolyte, can finish the preparation of galvanized pipe.

After the steel pipe fittings plating zinc on surface is finished, in the pipe fitting, outer tube wall surface and surface are all adhered to the zinc material and are formed zinc coat, but utilize in these, outer surface all forms the pipe-line system that the prior art galvanized pipe institute assembly of zinc coat is made, and can't be applied to carry zinc is had erodible, or can produce the material of chemical reaction with zinc, otherwise, the pipe-line system that the prior art galvanized pipe is made, will be owing to the stripping or the chemical change of zinc, influence is by the quality of its inner material, so, be applied to carry the occasion of these materials, generally be to adopt steel pipe fittings assembly pipe-line system, outer surface in steel pipe is coated with various corrosion resistance coatings again, and because the external surface area of pipe-line system is big, add after the pipe-line system assembly finishes, crisscross pipeline easily forms the dead angle, make the coating operational difficulty degree height of coating, and after after a while, these surface coatings peel off easily, must spray again, make that the degree difficult in maintenance of pipe-line system is high, so, how to overcome the problem of above-mentioned zinc corrosion, become the important topic of galvanized pipe.

Summary of the invention

The utility model provides a kind of one side zinc coating pipe, and its purpose is to overcome the prior art shortcoming, only forms zinc coat in the single face of tubular matrix, improving the range of application of galvanized pipe, and reduces the degree difficult in maintenance of its made pipe-line system.

The technical solution of the utility model is:

A kind of one side zinc coating pipe comprises a matrix and a zinc coat, and this matrix is the steel body, and these zinc-plated series of strata are attached to the formed zinc material of this matrix surface layer by Zinc material, and it is characterized in that: this zinc coat only is formed at the outer surface of this matrix.

The beneficial effect of technique scheme is: improved the range of application of galvanized pipe, reduced the degree difficult in maintenance of pipe-line system.

Description of drawings

Fig. 1 is the axial cutaway view of the utility model preferred embodiment

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

The utility model preferred embodiment as shown in Figure 1.

As shown in Figure 1, present embodiment comprises a matrix 10 and a zinc coat 20, wherein this matrix 10 is the steel body, this zinc coat 20 is that the zinc material is electroplated the zinc material layer that is attached to these matrix 10 surfaces, and this zinc coat 20 only is formed at the outer surface of this matrix 10, the inner pipe wall of this matrix 10 is plating zinc material not then, but steel plate face.

The utility model is owing to only electroplate at the outer surface of this matrix 10 and form this zinc coat, and the inner pipe wall of matrix 10 is plating zinc material not then.Therefore, the pipe-line system of utilizing the utility model to make, promptly can be used for conveying has erodible to zinc, perhaps can produce the material of chemical reaction with zinc, the problem of zinc corrosion can't take place, and the appearance of pipe-line system is because the formation of this zinc coat 20, can effectively avoid the salinity in the environment, moisture attacks influences its service life, and the combination stability height that this zinc coat 20 and this matrix are 10, can not peel off problem as corrosion resistance coating, so the utility model can effectively improve the range of application of galvanized pipe, and reduce the degree difficult in maintenance of its made pipe-line system.

Claims

1. an one side zinc coating pipe comprises a matrix and a zinc coat, and this matrix is the steel body, and these zinc-plated series of strata are attached to the formed zinc material of this matrix surface layer by Zinc material, and it is characterized in that: this zinc coat only is formed at the outer surface of this matrix.
