Application of stainless steel pipe making machine and welding on exhaust steam pipe

The continuous progress of stainless steel material processing for stainless steel pipe production field has brought a unique opportunity. Specifically, manufacturers are being asked to make parts like exhaust pipes that are lighter in weight, but still have to be corrosion resistant and meet strength requirements. In addition, the spatial limitations of the body emphasize the importance of formability. Typical applications include exhaust pipes, fuel lines, fuel nozzles, and other components. 

Stainless steel pipe making machine in the production of stainless steel pipe, the first shape of flat steel strip, then make its shape into a round tube. Once formed, the joints of the pipe must be welded together nicely. The quality of this weld greatly affects the formability of the part. Therefore, in order to obtain a welding shape that can meet the strict testing requirements in the manufacturing industry, it is very important to choose the right welding technology.

In recent years, due to the world energy shortage and the deteriorating environment, the automobile industry to improve the thermal efficiency of gas, reduce the weight of the car and other aspects of the demand for exhaust system put forward higher requirements, constantly improve the engine exhaust temperature. Exhaust manifold operating temperature from 750℃-800℃ to 900℃-950℃, or even higher; Exhaust manifolds and fasteners are converted from carbon steel to stainless steel. The muffler exhaust gas temperature increases, aggravates the degree of corrosion, must also use stainless steel.
