Abstract
The invention discloses a vehicle exhaust pipe made of a novel material. According to the technical scheme, the vehicle exhaust pipe utilizes a copper brazing double-layer steel tube which comprises smaller than 0.01% of C, smaller than 0.5% of Mn, smaller than 0.05% of P and smaller than 0.04% of S. The manufacturing process is simple, the two sides of a low carbon steel sheet containing C, Mn, P and S are copperized, then the low carbon steel sheet is made into a tube shape through rolling depression for twice, a tube with two layers of walls is obtained, and finally copper brazing is conducted to the tube through a brazing furnace in a reductive environment. The vehicle exhaust pipe made of the novel material has the advantages that the vehicle exhaust pipe can bear strong vibration when an engine stops or starts working, and the vehicle exhaust pipe can work well under bad conditions; by the adoption of the novel material of the exhaust pipe, noise can be greatly lowered, so that the vehicle exhaust pipe is broader in application range, durable, resistant to corrosion, high in strength and simple and convenient to process and manufacture.
Description
Technical field
The invention discloses a kind of automobile exhaust pipe of new material.
Background technique
At present, all there is following problem in many automobile exhaust pipes: must can bear the judder produced when motor is stopped during outlet pipe work, and after long-time use automobile, outlet pipe also there will be the king-sized problem of noise, and easily corrosion.Therefore, in order to overcome the above problems, the invention discloses a kind of automobile exhaust pipe of new material, judder when motor is stopped can be born, under severe conditions, also can well work; And due to the new material of outlet pipe, greatly noise problem can be reduced, so application is more extensive and durable in use, anticorrosive, intensity is high, and processing and fabricating is simple and convenient.
Summary of the invention
Object of the present invention is exactly the defect existed for prior art, provides a kind of automobile exhaust pipe of new material.
Its technological scheme is: automobile exhaust pipe adopts bundyweld tube, and its material composition is C content <0.01%, Mn content <0.5%, P content <0.05%, S content <0.04%.Manufacture process is fairly simple, copper facing is carried out on the two sides of the low carbon steel plate with C, Mn, P, S composition, is then rolled into tubulose through twice, make the pipe of two layers of walls, finally this pipe is carried out copper brazing by the hard soldering stove of reducibility environment.
Feature of the present invention: automobile exhaust pipe can bear judder when motor is stopped, under severe conditions, also can well work; And due to the new material of outlet pipe, greatly noise problem can be reduced, so application is more extensive and durable in use, anticorrosive, intensity is high, and processing and fabricating is simple and convenient.
Embodiment
Automobile exhaust pipe adopts bundyweld tube, and its material composition is C content <0.01%, Mn content <0.5%, P content <0.05%, S content <0.04%.Manufacture is that copper facing is carried out on the two sides of the low carbon steel plate with C, Mn, P, S composition, is then rolled into tubulose through twice, makes the pipe of two layers of walls, finally this pipe is carried out copper brazing by the hard soldering stove of reducibility environment.
In addition, the invention does not mean that specification limited to, and can change to some extent under the prerequisite not departing from design aim.
Claims (2)
