Large Diameter Stainless Steel Welded Tube Mill Pipe Production Line

Product Description

Large Diameter Stainless Steel Welded Tube Mill Pipe Production Line
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.
Large stainless steel welded pipe mill adopts automatic flexible forming technology.
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.
Large stainless steel welded pipe mill is mainly used for manufacturing the industrial pipe in chemical, the bottom sea, oil, gas delivering 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 equipment.
