Abstract
The invention relates to an anti-corrosion anti-rust composite steel pipe which comprises a steel pipe and is characterized in that a stainless steel composite layer is arranged on the periphery of the steel pipe, the stainless steel composite layer is a stainless steel pipe formed by winding and welding a stainless steel plate, the inner wall of the steel pipe is provided with a polyethylene powder coating anti-corrosion layer, the steel pipe and the stainless pipe are connected through rivet welding, and the steel pipe is a seamless steel pipe. The technical scheme is adopted, the stainless steel pipe is adopted outside the composite steel pipe to prevent rusting, the polyethylene powder coating is adopted inside the composite steel pipe to prevent corrosion, so that the service life of the steel pipe is greatly prolonged, the engineering cost is greatly reduced as compared with the full-height corrosion-resisting stainless steel pipe, and the manufacturing cost of the steel pipe with corrosion resistance and rust resistance is obviously lowered. The anti-corrosion anti-rust composite steel pipe is applicable to occasions having requirements for long service life and used for transporting corrosive fluid and is also suitably used as waste water drain pipeline.
Description
Technical field
The present invention relates to a kind of steel pipe, particularly relate to a kind of structure with composite steel tube of antiseptic and rustproof performance.
Background technique
Existing steel pipe mainly is divided into seam steel pipe and seamless steel pipe, and the anti-corrosion protection performance of steel pipe is poor, still; These steel pipes generally all are steel pipes of single material, need prevent the application of corroding at some, need to use to have antirustly to make steel pipe with material anti-corrosion capability; This can significantly increase the manufacture cost of steel pipe; And general steel pipe can not satisfy the requirement of its applied environment, therefore, need a kind ofly have antirust and novel steel tube anti-corrosion capability.
Summary of the invention
The purpose of this invention is to provide a kind of antiseptic and rustproof composite steel tube,, make this steel pipe not only have high antiseptic and rustproof performance, and have significantly reduced manufacture cost to overcome the above-mentioned defective of existing technology.
The objective of the invention is such realization: antiseptic and rustproof composite steel tube; Comprise steel pipe, it is characterized in that said steel pipe periphery is provided with the compound layer of stainless steel; The Stainless Steel Tube that the compound layer of said stainless steel is reeled and is welded by stainless-steel sheet; The steel pipe inwall is provided with the polyethylene powder coating anticorrosive coat, adopts rivet welding to be connected between steel pipe and the Stainless Steel Tube, and said steel pipe is a seamless steel pipe.
The present invention adopts with technique scheme; Antiseptic and rustproof composite steel tube adopts Stainless Steel Tube antirust outward; The interior polyethylene powders coating antiseptic that adopts; Prolonged the working life of steel pipe greatly, and engineering cost reduces than overall height corrosion-resistant stainless steel pipe significantly, has significantly reduced the manufacture cost of the steel pipe with anticorrosion embroidery performance.Antiseptic and rustproof composite steel tube of the present invention 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 a structural representation of the present invention.
Among the figure: 1 steel pipe, 2 Stainless Steel Tubes, 3 anticorrosive coats.
Embodiment
As shown in Figure 1, antiseptic and rustproof composite steel tube is provided with the compound layer of stainless steel by the seamless steel pipe periphery.Adopt the rivet hot weldering to be connected between the Stainless Steel Tube of the compound layer of stainless steel for forming at the outer coiling soldering stainless steel of seamless steel pipe steel plate, seamless steel pipe and Stainless Steel Tube, the steel pipe inwall is provided with the polyethylene powder coating anticorrosive coat.
On the basis of technique scheme, the compound layer of outer stainless steel can be reeled by stainless-steel sheet and welded or the vertical Stainless Steel Tube that is welded that wraps.In addition, according to the requirement of different rustless properties, the stainless-steel sheet material can freely be selected different stainless-steel sheet materials.According to the requirement of different Corrosion Protections, can freely select the coating of different Corrosion Protections equally.The coating of anticorrosive coat can apply once, also can apply twice, three times, selects to apply number of times according to the requirement of Corrosion Protection.
The compound layer of stainless steel is by stainless-steel sheet welding or the vertical bag Stainless Steel Tube that is welded of reeling, except that above-mentioned welding or the vertical bag of seamless steel pipe, reeling is welded.Also can be earlier being welded into Stainless Steel Tube, being nested with outside seamless steel pipe then, and between seamless steel pipe and Stainless Steel Tube, adopting glue to be connected with reel welding or vertical bag of stainless-steel sheet.Antiseptic and rustproof composite steel tube owing to be provided with antirust steel pipe and anticorrosive coat, makes prolong greatly the working life of steel pipe, and engineering cost reduces than overall height corrosion-resistant stainless steel pipe significantly, has significantly reduced the manufacture cost of the steel pipe with anticorrosion embroidery performance.Antiseptic and rustproof composite steel tube of the present invention 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 through any suitable manner, and it falls within the disclosed scope of the present invention equally.In addition, also can carry out combination in any between the various mode of execution of the present invention, as long as it is without prejudice to thought of the present invention, it should be regarded as the disclosed content of the present invention equally.
More than combine accompanying drawing to describe preferred implementation of the present invention in detail; But; The present invention is not limited to the detail in the above-mentioned mode of execution; In technical conceive scope of the present invention, can carry out multiple simple variant to technological scheme of the present invention, these simple variant all belong to protection scope of the present invention.Protection scope of the present invention is defined by the claims.
