What are the manufacturing processes of stainless steel coils?

What are the manufacturing processes of stainless steel coils? The production of stainless steel coil goes through three steps: tube making, bending and cutting. The first step, using stainless steel strip as raw material, the pipe is continuously produced online by pipe making machine. Then bending, that is, conveying the stainless steel pipes after pipe making to a pipe bender, bending the pipes with a pipe bender or other bending equipment, conveying the pipes to a second pipe bender after the first pipe bender is completed, and successively bending the pipes until all the stainless steel pipes are bent into a single continuous pipe; Then, cut and bend the one-piece continuous elbow. After the pipe head is cut to length, the length of the single-piece coil is15 ~133m, and there is no radial weld.
