Abstract
The utility model discloses a duplex metal composite pipeline, which is formed by pipe bodies. Each pipe body is formed by a stainless steel pipe lining and a carbon steel pipe arranged outside the stainless steel lining. The duplex metal composite pipeline is low in manufacture cost, strong in corrosion resistance, abrasion resistance and external force resistance, long in service life and the like. Simultaneously, cold extruding composite technology has the advantages of being low in energy consumption, high in efficiency, high in yield rate and the like. Thus, the duplex metal composite pipeline is excellent in combination strength, compactness and yield rate, and stable in product performance.
Description
Technical field
The utility model relates to the multiple tube field, is specifically related to a kind of bimetal compound pipeline.
Background technique
One to the fluid-transporting tubing that is called as " industrial blood vessels ", and its application almost relates to all industry and civilian department, so various countries all attach great importance to its production and development.With the steel pipe is example, each main developed industrial country man, and its proportion of production accounts for the 15%-20% of steel total amount, and China only accounts for 8-10% at present.
The pipeline that uses now all belongs to single material basically, and performance is more single, can not have advantages such as sterilization, anticorrosion, withstand voltage, anti-aging and cost be low simultaneously concurrently, always has defective.
For example, (1) fine copper pipeline is though have superior corrosion resistant, wear-resisting, sterilization and keep function such as fluid cleaning; But the fine copper pipeline costs an arm and a leg; And owing to himself have plasticity, cause pipeline to hit flat, crooked and distortion easily, so leak, major accident such as burn into explosion.
(2) Coating Steel Pipe, though cheap, in air, very easily corrode, not only working life low, and cause the secondary pollution of fluid, influence people ' s health.
Plastic pipes such as the PE that (3) is now just using, PEX, PVC; Have advantages such as cost is low, light and handy, easy to connect, but their easy ageing, working life is low; And not anti-external force punching press, especially the lead as the stable Ji of plastic hot very easily causes pollution of heavy metals through fluid to human body.
A kind of metal compounded pipe utilizes copper tube as liner, at copper tube outer installment carbon steel tubing as parent tube; This multiple tube has multiple advantages such as anticorrosion, withstand voltage concurrently; But because the red copper cost is higher, the fabricating cost of multiple tube is provided significantly, has been unfavorable for applying of this pipeline.
The model utility content
The purpose of the utility model is to overcome the deficiency of existing technology, and the bimetal compound pipeline that a kind of cost is low and have good anticorrosion compression resistance is provided.
To achieve these goals, the technological scheme of the utility model employing is:
Said bimetal compound pipeline is made up of body, and said body is by the Stainless Steel Tube liner and be located at the outside carbon steel tubing of Stainless Steel Tube liner and constitute.
The Stainless Steel Tube liner of said body and carbon steel tubing interference fit.
Said Stainless Steel Tube thickness of inner lining is 0.3～0.5mm, and said carbon steel tubing thickness is 1.0～5.0mm.
The advantage of the utility model is: said bimetal compound pipeline; With the superior carbon steel tubing of cheap and crashproof intensity is parent tube; The Stainless Steel Tube that reduces with cost is as liner; Make pure Stainless Steel Tube liner reach critical plastic deformation through unique cold extruding technique, so with compound the combining together of carbon steel tubing zero-clearance physics interference, become environmental protection bimetal compound fluid conveyance conduit.Said bimetal compound pipeline; Have corrosion resistant concurrently, wear-resisting, external force resistance ability reaches functions such as long service life by force; Energy consumption is low, efficient is fast and the high outstanding advantage of productivity because the cold hobbing complex technique has simultaneously; It is optimum that bimetal pipeline adhesive strength, compactness and molding rate after compound all reaches, and product performance are more stable.
Description of drawings
Face the content of each width of cloth accompanying drawing expression of the utility model specification and the mark among the figure down and make brief description:
Fig. 1 is the structural representation of the utility model bimetal compound pipeline;
Mark among the above-mentioned figure is:
1, body, 2, the Stainless Steel Tube liner, 3, carbon steel tubing.
Embodiment
Contrast accompanying drawing below,, the embodiment of the utility model is done further detailed explanation through description to optimum embodiment.
As shown in Figure 1, said bimetal compound pipeline is made up of body 1, and body 1 is by Stainless Steel Tube liner 2 and be located at the outside carbon steel tubings 3 of Stainless Steel Tube liner 2 and constitute.
Said bimetal compound pipeline, Stainless Steel Tube liner 2 have corrosion resistant, advantage such as wear-resisting; Carbon steel tubing 3 is set outside Stainless Steel Tube liner 2, because carbon steel tubing 3 good rigidlies, said bimetal compound pipeline is not easy distortion, can anti-extraneous external impacts, and the long service life of bimetal compound pipeline.
For further guaranteeing the performance of said bimetal compound pipeline; Through cold-drawn complex technique cold hobbing Stainless Steel Tube liner 2; Make it form body 1 with carbon steel tubing 3; Cold hobbing can make Stainless Steel Tube liner 2 reach threshold state moulding distortion takes place to expand and outside carbon steel tubing 3 generation interference fit, fit tightly.The cold-drawn complex technique makes adhesive strength, compactness and the molding rate of Stainless Steel Tube and carbon steel tubing 3 all reach optimization, and energy consumption is low, and speed is fast, can make that performance of products is more stable, structure is more perfect.The Stainless Steel Tube liner 2 and carbon steel tubing 3 interference fit of body 1.
For further guaranteeing the performance of said bimetal compound pipeline, make bimetal compound pipeline satisfy advantages such as cost is lower, weight is lighter, Stainless Steel Tube liner 2 thickness are 0.3～0.5mm, carbon steel tubing 3 thickness are 1.0～5.0mm.
Said bimetal compound pipeline; Because the stainless steel cost is far below red copper; The cost of bimetal pipeline is descended significantly, can reduce the cost of production of pipeline greatly, thereby price has been established in the industrial especially universal use in ocean engineering and raw material are basic for supply water in town and country in modern times.
Above the utility model has been carried out exemplary description; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
