Stainless Steel Welded Pipe Making Machine
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 edge of the steel plate is melted by making use of the proximity effect and skin effect of high frequency current. Then, the plate is extruded and welded into the pipe by extruding roller. Straight seam welded pipe mill also is called ERW mill.
The forming styles of straight seam welded 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, the ERW line can be divided to API standard pipe mill and national standard mill.
API standard straight seam HF welded pipe mill introduction is mainly used for producing the high grade pipe such as oil, gas delivering and casing pipe in the oil well. These high grade pipes strictly require the pipe material and pipe quality. This kind of straight seam HF welded pipe mill has IF annealing, air cooling roller rail, UT detector, high pressure hydrotester, diameter drifter and other detect equipments and art craft.
National standard mill is mainly used for manufacturing the low pressure fluid pipe and structure pipe.

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.
Stainless steel pipe welded mill adopts total 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.

Stainless steel welded pipe mill is mainly used for manufacturing the industrial pipe in chemical, the bottom sea, oil, gas delivering and other fields. 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 hydro tester and other detector equipment.
