Abstract
The invention discloses an anti-corrosion and anti-rust compound steel pipe, and relates to the technical field of civil engineering. The anti-corrosion and anti-rust compound steel pipe comprises a pipe body, wherein a ceramic thermal insulating layer is arranged on the inner wall of the pipe body; a carbon layer is arranged on the outer wall of the pipe body; a sand inclusion layer is compounded on the outer surface of the carbon layer; an outer protection layer is arranged on the outer surface of the sand inclusion layer. Compared with the prior art, for the anti-corrosion and anti-rust compound steel pipe disclosed by the invention, the inner and outer walls of the steel pipe is high in anti-rust performance; the service life of the steel pipe is greatly prolonged; the construction cost is greatly reduced compared with that when full-height anti-rust stainless steel is adopted; the manufacture cost of the steel pipes with anti-corrosion and anti-rust performances is remarkably reduced; the rigidity and the intensity of the steel pipes are greatly enhanced by compounding the carbon layer and the sand inclusion layer, so that the anti-corrosion and anti-rust compound steel pipe is applicable for supporting pieces, such as piers and pillars, of civil engineering structures.
Description
Technical field
The present invention 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.
Summary of the invention
The invention provides a kind of anti-corrosion anti-rust composite steel pipe, 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 solution adopted in the present invention 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 present invention 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 invention.
Detailed description of the invention
Below in conjunction with attached Example, the invention will be further described:
The present invention 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 present invention 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.
