Abstract
The invention discloses a metal pipeline which comprises a metal pipeline body, wherein an anti-corrosion sleeve is arranged outside the metal pipeline body; a plurality of annularly arrayed insulation supporting blocks are symmetrically arranged at two ends of the anti-corrosion sleeve; the thickness of the anti-corrosion sleeve is the same as that of the metal pipeline body; and the heights of the insulation supporting blocks are greater than the thickness of the anti-corrosion sleeve. According to the metal pipeline, a phenomenon of short circuit between a steel bushing and the metal pipeline is avoided; and when the metal pipeline is used and invaded by electrolytes, such as water and soil, the anti-corrosion sleeve can be used for effectively reducing the electrochemical corrosion on the metal pipeline, so that the service life of the metal pipeline is prolonged.
Description
Technical field
The present invention relates to a kind of metallic conduit, particularly be a kind of metallic conduit that is used in the Steel Sleeve.
Background technique
Metallic conduit is one of capital equipment of carrying liquids and gases.Outside metallic conduit, be typically provided with Steel Sleeve; Play the effect of protective money metal conduit; But steel pipeline also can produce corrosion to metallic conduit, influences the working life of metallic conduit, and wherein causing reason for corrosion mainly is to be short-circuited between Steel Sleeve and the metallic conduit.Simultaneously, owing to have point of contact between metallic conduit and the Steel Sleeve, make through section Steel Sleeve ground connection; Annular space at metallic conduit and Steel Sleeve; If there are electrolyte such as water or soil to immerse, metallic conduit very easily suffers electrochemical corrosion, influences the working life of metallic conduit.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind ofly to avoid being short-circuited between Steel Sleeve and the metallic conduit and the metallic conduit of electrochemical corrosion resistant.
Technical solution of the present invention is achieved in that a kind of metallic conduit, comprises the metallic conduit body, and said metallic conduit body is provided with the corrosion protection cover outward; The two ends of said corrosion protection cover are arranged with the dielectric support block of a plurality of annular arrays.
Preferably: the thickness of said corrosion protection cover is identical with the metallic conduit body thickness.
Preferably: the height of said dielectric support block is greater than the thickness of corrosion protection cover.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Metallic conduit of the present invention, because the metallic conduit body is provided with the corrosion protection cover outward, the two ends of corrosion protection cover are arranged with the dielectric support block of a plurality of annular arrays, have avoided being short-circuited between Steel Sleeve and the metallic conduit; In the process of using, when electrolyte such as water or soil immersed, the corrosion protection cover can effectively reduce the electrochemical corrosion that metallic conduit receives, and has prolonged the working life of metallic conduit.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the stereogram of metallic conduit of the present invention;
Accompanying drawing 2 is the structural representation of metallic conduit user mode of the present invention;
Wherein: 1, metallic conduit body; 2, corrosion protection cover; 3, dielectric support block; 4, Steel Sleeve.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of metallic conduit shown in accompanying drawing 1 comprises metallic conduit body 1, the said metallic conduit body 1 outer corrosion protection cover 2 that is provided with; The two ends of said corrosion protection cover 2 are arranged with the dielectric support block 3 of a plurality of annular arrays; The thickness of said corrosion protection cover 2 is identical with the thickness of metallic conduit body 1; The height of said dielectric support block 3 is greater than the thickness of corrosion protection cover 2.
Like accompanying drawing 2 described a kind of metallic conduits of the present invention, in the process of using,, avoided being short-circuited between Steel Sleeve 4 and metallic conduit 1 body owing to be separated with corrosion protection cover 2 and dielectric support block 3 between metallic conduit body 1 and the Steel Sleeve 4; When electrolyte such as water or soil immersed, corrosion protection cover 2 can effectively reduce the electrochemical corrosion that metallic conduit body 1 receives, and has prolonged the working life of metallic conduit body 1.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (3)
1. a metallic conduit comprises the metallic conduit body, it is characterized in that: said metallic conduit body is provided with the corrosion protection cover outward; The two ends of said corrosion protection cover are arranged with the dielectric support block of a plurality of annular arrays.
2. metallic conduit according to claim 1 is characterized in that: the thickness of said corrosion protection cover is identical with the metallic conduit body thickness.
