Abstract
The utility model discloses a kind of anti-corrosion anti-rust composite steel pipe, relate to technical field of civil engineering, include body, described inboard wall of tube body is provided with ceramic thermal barrier layer, described tube wall is provided with one deck carbon element layer, described carbon element layer external surface is compounded with a stratified sand layer, this burning into sand layer external surface is provided with external protection coating, compared with prior art, the inside and outside wall of this steel pipe has high antiseptic property, extend the application life of steel pipe greatly, and construction costs also significantly reduces than overall height corrosion-resistant stainless steel, significantly reduce and there is anticorrosion, the manufacturing cost of the steel pipe of rustless property, and be compounded with carbon element layer and burning into sand layer, the Rigidity and strength of steel pipe is improved greatly, is suitable for the support member such as bridge pier and pillar of civil engineering structure.
Description
Technical field
The utility model relates to technical field of civil engineering, especially a kind of anti-corrosion anti-rust composite steel pipe.
Background technology
The steel pipe of existing civil engineering is mainly divided into seam steel pipe and seamless steel pipe, and the structure of these steel pipes also exists perishable and problem that is that get rusty, and because corrosion causes structural failure or destruction, the property even loss of life are of common occurrence.Steel pipe is generally the steel pipe of single material, and need at some the application scenario preventing corrosion, then need to do severe anti-corrosion protection at steel pipe surfaces externally and internally, common way is zinc-plated at steel pipe inner wall or plates other impregnating fluid.Situation according to current construction usage is seen, the antiseptic property of this way is not high, cause life cycle short, and rigidity is inadequate.
Utility model content
The utility model provides a kind of anti-corrosion anti-rust composite steel pipe, and it can solve existing common steel tube antiseptic property short problem in difference application life.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: it includes body, and described inboard wall of tube body is provided with ceramic thermal barrier layer, and described tube wall is provided with one deck carbon element layer, described carbon element layer external surface is compounded with a stratified sand layer, and this burning into sand layer external surface is provided with external protection coating.
In technique scheme, scheme can also be more specifically: described burning into sand layer is quartz sand layer.
Further: described external protection coating adopts nano polyaniline anticorrosive paint to make.
Owing to adopting technique scheme, the utility model compared with prior art, has following beneficial effect:
Owing to being provided with one deck ceramic thermal barrier layer at inboard wall of tube body, tube wall is provided with carbon element layer, burning into sand layer and external protection coating successively, the inside and outside wall of steel pipe is made to have high antiseptic property, extend the application life of steel pipe greatly, and construction costs also significantly reduces than overall height corrosion-resistant stainless steel, significantly reduce the manufacturing cost of steel pipe with anticorrosion, rustless property; And be compounded with carbon element layer and burning into sand layer, the Rigidity and strength of steel pipe is improved greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with attached Example, the utility model is described in further detail:
The utility model as shown in Figure 1, it includes body 4, inboard wall of tube body is coated with ceramic heat insulating coating 5, body 4 outer wall is provided with one deck carbon element layer 3, carbon element layer 3 external surface is compounded with one deck quartz sand layer 2, this is that quartz sand layer external surface is provided with one deck external protection coating 1, and this external protection coating adopts nano polyaniline anticorrosive paint to make.Because the utility model is compounded with carbon element layer and burning into sand layer, the Rigidity and strength of steel pipe is improved greatly, can be used for the support member such as bridge pier and pillar of civil engineering structure.
