Abstract
A composite steel pipe comprises a steel base material layer (1), an outer corrosion-rust resisting layer contacted with the outer circumferential surface of the steel base material layer (1), and an inner corrosion-rust resisting layer contacted with the inner circumferential surface of the steel base material layer. As for the inner layer and the outer layer of the composite steel pipe, the same or different corrosion-rust resisting materials can be selected according to the different requirements for the corrosion-rust resisting property of the contact mediums of the inner wall and the outer wall of the steel pipe, for example, due to the composite of stainless steel plate and steel plate, the service life of the composite steel pipe is greatly prolonged, the engineering construction cost is remarkably reduced compared with that of a complete and high corrosion-resistance stainless steel pipe, and the manufacturing cost of the steel pipe with corrosion-rust resisting property is obviously lowered. The composite steel pipe is suitable in occasions where long service life is required and corrosive fluid is conveyed, and also suitable for being used as a sewage discharge pipeline.
Description
Technical field
The utility model relates to a kind of steel pipe, particularly, relates to a kind of composite steel tube.
Background technique
Existing steel pipe mainly is divided into seam steel pipe and seamless steel pipe.But these steel pipes generally all are steel pipes of single material, need prevent the application of corroding at some, need to use the material with anti-corrosion capability to make steel pipe, and this can significantly increase the manufacture cost of steel pipe.
Therefore, need a kind of novel composite steel tube.
The model utility content
The purpose of this utility model provides a kind of composite steel tube, to overcome the above-mentioned defective of prior art, makes this steel pipe not only have high anticorrosion embroidery performance, and has significantly reduced manufacture cost.
Above-mentioned purpose is achieved through the following technical solutions: composite steel tube comprises steel substrate layer, the outer anticorrosion interior anticorrosion embroidery layer of embroidering layer and contacting with the inner peripheral surface of this steel substrate layer that contacts with the outer circumferential face of this steel substrate layer.
Preferably, described outer anticorrosion embroidery layer is the compound layer of outer stainless steel, and described interior anticorrosion embroidery layer is the compound layer of interior stainless steel.
Preferably, the compound layer of compound layer of described outer stainless steel and interior stainless steel is reeled by stainless-steel sheet and is formed.
Preferably, described composite steel tube is the seam steel pipe, this composite steel tube also comprise the base material overlay cladding of the seam that is used to engage described steel substrate layer, the outer stainless steel weld overlays and being used to that is used to engage the seam of the compound layer of described outer stainless steel engage described in the interior stainless steel weld overlays of seam of the compound layer of stainless steel.
By technique scheme of the present utility model, because described composite steel tube comprises steel substrate layer, outer anticorrosion embroidery layer and interior anticorrosion embroidery layer, because the internal and external layer of this composite steel tube can be according to the different preventing corrosivity requirement of the contact medium of steel pipe inside and outside wall, select the anticorrosion embroidery material (for example stainless-steel sheet) of identical or different material compound, make prolong greatly the working life of steel pipe, engineering cost reduces significantly than overall height corrosion-resistant stainless steel pipe, has significantly reduced the manufacture cost of the steel pipe with anticorrosion embroidery performance.Composite steel tube of the present utility model is fit to require the occasion that working life is long, be used to carry corrosive fluid, also is suitable as sewage vent line.
Description of drawings
Fig. 1 is the structural representation of the composite steel tube of the utility model embodiment.
Among the figure: 1 steel substrate layer; The compound layer of 2 outer stainless steels; The compound layer of stainless steel in 3; 4 base material overlay claddings; 5 outer stainless steel weld overlays; Stainless steel weld overlays in 6
Embodiment
The embodiment of the utility model composite steel tube is described below in conjunction with accompanying drawing.
The basic technical scheme of the utility model composite steel tube is: this composite steel tube comprises steel substrate layer 1, the outer anticorrosion interior anticorrosion embroidery layer of embroidering layer and contacting with the inner peripheral surface of this steel substrate layer that contacts with the outer circumferential face of this steel substrate layer.
On the basis of technique scheme, referring to shown in Figure 1, preferably, described outer anticorrosion embroidery layer can be the compound layer 2 of outer stainless steel, and described interior anticorrosion embroidery layer can be the compound layer 3 of interior stainless steel.Being somebody's turn to do the compound layer 3 of compound layer 2 of outer stainless steel and interior stainless steel all can be formed by the stainless-steel sheet coiling.In addition, according to the requirement of different Corrosion Protections, the compound layer 2 of described outer stainless steel can freely be selected different stainless-steel sheet materials with the steel plate materials of the compound layer 3 of interior stainless steel, for example 316 stainless-steel sheets, 304 stainless steels or 202 stainless steels etc.
Referring to shown in Figure 1, composite steel tube among Fig. 1 is the seam steel pipe, during fabrication, can in turn the compound layer 3 of interior stainless steel, steel substrate layer 1 and the compound layer 2 of outer stainless steel be wound into tubulose, correspondingly, this composite steel tube also comprise the base material overlay cladding 4 of the seam that is used to engage described steel substrate layer, the outer stainless steel weld overlays 5 and being used to that is used to engage the seam of the compound layer of described outer stainless steel engage described in the interior stainless steel weld overlays 6 of seam of the compound layer of stainless steel, thereby form seam composite steel tube shown in Figure 1.Certainly, in technical conceive scope of the present utility model, composite steel tube of the present utility model also can be a seamless steel pipe.
By last description as seen, because described composite steel tube comprises steel substrate layer, outer anticorrosion embroidery layer and interior anticorrosion embroidery layer, because the internal and external layer of this composite steel tube can be according to the different preventing corrosivity requirement of the contact medium of steel pipe inside and outside wall, select the anticorrosion embroidery material (for example stainless-steel sheet) of identical or different material compound, make prolong greatly the working life of steel pipe, engineering cost reduces significantly than overall height corrosion-resistant stainless steel pipe, has significantly reduced the manufacture cost of the steel pipe with anticorrosion embroidery performance.Composite steel tube of the present utility model is fit to require the occasion that working life is long, be used to carry corrosive fluid, also is suitable as sewage vent line.
Each concrete technical characteristics described in above-mentioned embodiment can carry out combination in any by any suitable manner, and it falls within the scope disclosed in the utility model equally.In addition, also can carry out combination in any between the various mode of execution of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
Below describe preferred implementation of the present utility model in conjunction with the accompanying drawings in detail; but; the utility model is not limited to the detail in the above-mentioned mode of execution; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.Protection domain of the present utility model is defined by the claims.
