Abstract
The utility model relates to a metal pipeline which comprises a metal pipeline body, wherein a corrosion-preventing sleeve is arranged outside the metal pipeline body, a plurality of annular arrayed insulation support blocks are symmetrically arranged on two ends of the corrosion-preventing sleeve, the thickness of the corrosion-preventing sleeve is equal to the thickness of the metal pipeline body, and the height of the insulation support block is more than the thickness of the corrosion-preventing sleeve. According to the metal pipeline provided by the utility model, the short circuit between a steel sleeve and the metal pipeline is avoided, in a use process, when water or soil and other electrolytes immerse, the corrosion-preventing sleeve can effectively reduce electrochemical corrosion caused to the metal pipeline, and thus the service life of the metal pipeline is prolonged.
Description
Technical field
The utility model relates to a kind of metallic conduit, particularly be a kind of for the metallic conduit 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 protection metallic conduit; but steel pipeline also can produce corrosion to metallic conduit, affects the working life of metallic conduit, and the reason that wherein causes 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 the electrolyte such as water or soil to immerse, metallic conduit very easily suffers electrochemical corrosion, affects the working life of metallic conduit.
The model utility content
The utility model purpose is to provide a kind of to avoid being short-circuited between Steel Sleeve and the metallic conduit and the metallic conduit of electrochemical corrosion resistant in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of metallic conduit, comprise the metallic conduit body, and described metallic conduit body is provided with the corrosion protection cover outward; The two ends of described corrosion protection cover are arranged with the dielectric support block of a plurality of annular arrays.
Preferably: the thickness of described corrosion protection cover is identical with the metallic conduit body thickness.
Preferably: the height of described dielectric support block is greater than the thickness of corrosion protection cover.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Metallic conduit of the present utility model, 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 the electrolyte such as water or soil immersed, the corrosion protection cover can effectively reduce the electrochemical corrosion that metallic conduit is subject to, and has prolonged the working life of metallic conduit.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the stereogram of metallic conduit of the present utility model;
Accompanying drawing 2 is the structural representation that metallic conduit of the present utility model uses state;
Wherein: 1, metallic conduit body; 2, corrosion protection cover; 3, dielectric support block; 4, Steel Sleeve.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of metallic conduit as shown in Figure 1 comprises metallic conduit body 1, the described metallic conduit body 1 outer corrosion protection cover 2 that is provided with; The two ends of described corrosion protection cover 2 are arranged with the dielectric support block 3 of a plurality of annular arrays; The thickness of described corrosion protection cover 2 is identical with the thickness of metallic conduit body 1; The height of described dielectric support block 3 is greater than the thickness of corrosion protection cover 2.
Such as accompanying drawing 2 described a kind of metallic conduits described in the utility model, in the process of using, owing to be separated with corrosion protection cover 2 and dielectric support block 3 between metallic conduit body 1 and the Steel Sleeve 4, avoided being short-circuited between Steel Sleeve 4 and metallic conduit 1 body; When the electrolyte such as water or soil immersed, corrosion protection cover 2 can effectively reduce the electrochemical corrosion that metallic conduit body 1 is subject to, and has prolonged the working life of metallic conduit body 1.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
Claims (3)
1. a metallic conduit comprises the metallic conduit body, it is characterized in that: described metallic conduit body is provided with the corrosion protection cover outward; The two ends of described 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 described corrosion protection cover is identical with the metallic conduit body thickness.
