China High Precision Automatic Customized ERW Stainless Steel Welded Steel Pipe Mill

Stainless Steel Welded Pipe Mill introduction:
The plate in certain width after slitting line and stripping is unfolded and leveled. Then, they are sent into forming machine. Used the roller, the plate is bent into pipe state. The pipe is welded by plasma welder and Tig welder.
The forming styles of stainless steel welding pipe can be divided into roll forming, flexible forming, full auto flexible forming. The mill developed by our company adopts roll forming when having small diameter (Φ≤114). Flexible forming or full automatic flexible forming is adopted when having middle or large diameter(Φ≤711).
In recent year, our company developed the precise control forming. The advantage of this kind forming is to guarantee the excellent forming quality in rough forming section through the precise control. Then it is no need to have the repair management in precise forming section. Therefore, the precise forming in this forming method does not need to change the roller. All the forming section does not need to change the roller, which solves the problem of the change in precise forming section and non-change in rough forming section. Therefore, it saves the roller investment and decreases the time of roller changing. Besides, during the diameter changing, all are controlled by industrial computer. The roller will automatically reach the position by inputting the pipe diameter, pipe wall thickness, material and other parameters. It largely improves the mill efficiency and pipe qualified rate. This forming method is suitable for medium and large mill from 219mm to 711mm, which saves the investment and improves the efficiency.
According to the pipe application, stainless steel pipe welding machine can be divided to industrial pipe model and decoration pipe model.
Industrial pipe welding mill is mainly used for manufacturing the industrial pipe in chemical, car, oil, and other field. The pipe requirement on the material and quality is very strict. The machine has internal welding seam leveling treatment, solution annealing, X-ray detector, UT detector, high pressure hydrotester, and other detector equipments and art craft.
Decoration pipe mill is mainly used for manufacturing the pipe for decoration.
