Abstract
The utility model relates to a pipe with a corrosion-proof nickel layer, which comprises a substrate steel strip which is rolled and welded into a pipe and is characterized in that a corrosion-proof nickel layer is plated on one side of the substrate steel strip, and the substrate steel strip which is plated with the corrosion-proof nickel layer is rolled and welded into the pipe with the corrosion-proof nickel layer on the inner surface. The pipe with a corrosion-proof nickel layer has the beneficial effects that the corrosion-proof ability of the inner surface of pipelines in the automobile and refrigeration industries is improved, and the reliability and the safety of devices in the automobile and refrigeration industries are improved. Since metal nickel tools have strong corrosion resistance, thereby the corrosion resistance of an oil pipe after nickel plating treatment is improved by 10 to 20 times compared with an existing product. Furthermore, since a thin layer of iron-nickel alloy is generated between a nickel-plated layer and the steel strip due to high temperature treatment, the abrasive resistance of the pipe to fluid is improved, the binding force between the nickel layer and the steel strip is improved on one hand, and the corrosion-proof ability is improved by three times compared with a common nickel-plated layer on the other hand. The pipe also has excellent welding performance simultaneously.
Description
Technical field
The utility model belongs to tubing, particularly a kind of tubing with anticorrosion nickel dam that is applicable to that automobile, air-conditioning, refrigerator, refrigeration industry are used.
Background technique
Automobile industry at home at present, the tubing that air-conditioning, refrigerator, refrigeration industry use. adopt individual layer or double coiled welded tube mostly.Especially the tubing of the brake system of automobile industry, oil-fired system, power steering system use adopts individual layer or double coiled welded tube to replace steel pipe and seamless steel pipe basically; The tubing that air-conditioning, refrigerator, refrigeration industry use also adopts individual layer or double coiled welded tube to replace copper pipe mostly.Because individual layer or double coiled welded tube have internal surface turbidity test height, the intensity advantage greater than steel pipe.Help environmental protection, simplify working process, reduce cost, so its purposes more and more widely.But along with using scope more and more widely, automobile and refrigeration industry are employed new technology, new material is more and more higher to the requirement of individual layer or bimetallic tube.Especially the antiseptic property of individual layer or double coiled welded tube internal surface is had higher requirement.Such as: automobile industry is because the high standard of energy shortage and environmental protection.A large amount of at present gasoline that contain ethanol that adopt, this steam oil ratio (SOR) regular gasoline wants much serious to the corrosion of the internal surface of transport pipe.The existing single laminate roll welded tube that uses does not all also have desirable preservative efficacy.Event short-term inner oil tube internal surface can also be held non-corrosive reluctantly eventually, but the corrosion meeting of time one long oil pipe inside has a strong impact on the heavy wear that the normal gusher of engine electric spray system causes engine cylinder-body.This Security and reliability effect to automobile is huge.For expensive automobile, transport pipe but is a key components and parts in the car load.Therefore, at this defective of present China transport pipe, develop corrosion-resistant tubing and become trend of the times.
The model utility content
The purpose of this utility model is intended to overcome the defective of above-mentioned existence, and a kind of tubing with anticorrosion nickel dam is provided, and it effectively improves the internal surface antiseptic power of automobile and refrigeration industry pipeline, improves the reliability and the Security of automobile and refrigeration industry equipment.
Realize that the technological scheme that the purpose of this utility model adopted is: a kind of tubing with anticorrosion nickel dam, comprise that volume is welded into the base material steel band of tubing, it is characterized in that: the one side at the base material steel band is coated with anticorrosion nickel dam, and the base material steel band pipe crimping welding that is coated with anticorrosion nickel dam forms the tubing that internal surface has anticorrosion nickel dam.
Above-mentioned anticorrosion nickel dam is thick to be 3-5 μ.
Above-mentioned anticorrosion nickel dam also has one deck layer of iron-nickel alloy through high temperature processing and steel band junction plane.
The beneficial effects of the utility model are: improved the antiseptic power of the internal surface of automobile and refrigeration industry pipeline, improved the reliability and the Security of automobile and refrigeration industry equipment.Because metallic nickel has powerful corrosion resistance, so improve 10-20 doubly than the corrosion resistance of existing product through the oil pipe of Nickel Plating Treatment.Because through high temperature processing, make the very thin one deck layer of iron-nickel alloy of nickeling layer and steel band generation again, the wear resistance that this has not only increased its convection cell has improved the combination force of nickel dam and steel band, has improved 3 times again to the anti-corrosion capacity of common nickeling layer.Has remarkable weldability simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Details are as follows to embodiment structure characteristic that foundation the utility model provides below in conjunction with accompanying drawing and preferred embodiment:
A kind of tubing with anticorrosion nickel dam. comprise that volume is welded into the base material steel band of tubing, be coated with anticorrosion nickel dam 2 in the one side of base material steel band 1, anticorrosion nickel dam is thick to be 3-5 μ.Because metallic nickel has powerful corrosion resistance. so improve greatly than the corrosion resistance of existing product the oil pipe inside of process Nickel Plating Treatment, its anticorrosion nickel dam also can make nickeling layer and steel band junction plane also have one deck layer of iron-nickel alloy 3 through high temperature processing, has improved 3 times again than common nickel plating corrosion resistance.Both improve the combination force of nickel dam and steel band, improved the anti-corrosion capacity of nickeling layer again.The tubing steel band pipe crimping welded pipe seam 4 that is coated with anticorrosion nickel dam at last forms the tubing that internal surface has anticorrosion nickel dam.
The utility model is specially adapted to oil delivering pipe of car.
The above. only be preferred embodiment of the present utility model. be not structure of the present utility model to be made the every foundation of any pro forma restriction technical spirit of the present utility model any simple modification equivalent variations that above embodiment did is all given preferential treatment to the families of the armymen and martyrs in the model of the technical solution of the utility model with modification.
Claims (3)
1, a kind of tubing with anticorrosion nickel dam comprises that volume is welded into the base material steel band of tubing, and it is characterized in that: the one side at the base material steel band is coated with anticorrosion nickel dam, and the base material steel band pipe crimping welding that is coated with anticorrosion nickel dam forms the tubing that internal surface has anticorrosion nickel dam.
2, the tubing with anticorrosion nickel dam according to claim 1 is characterized in that: above-mentioned anticorrosion nickel dam is thick to be 3-5 μ.
