Product Description

High Precision Automatic Customized ERW Pipe Mill Line

The steel coil after slitting is unfolded and leveled. Then, they are sent into forming machine. Used the roll, the coil is bent into pipe state. The edge of the steel coil is melted by making use of the proximity effect and skin effect of high frequency current. Then, the coil is extruded and welded into the pipe by extruding roller. Then, the final pipe is manufactured out after the IF annealing and cut to length. API grade ERW pipe mill is mainly used for producing the high-grade pipe such as oil and gas delivering and casing pipe in the oil well. These high-grade pipes strictly require the pipe material and pipe quality. The API grade ERW pipe mill has IF annealing, air cooling roller, UT detector, high pressure hydrotester and other detect equipment. 
The forming styles of ERW pipe can be divided into roll forming, flexible forming, full auto flexible forming. The mill developed by our company adopts roll forming when producing small diameter pipe (Φ≤114). Flexible forming or fully automatic flexible forming is adopted when producing large diameter pipe (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 machine does not need to change the roll. All the forming section does not need to change the roll, which solves the problem of the change in precise forming section and non-change in rough forming section. Therefore, it saves the roll investment and decreases the time of roll changing. Besides, during the diameter changing, all are controlled by computer. The roll will automatically reach the position by inputting the pipe diameter, pipe thickness, material and other parameters. It largely improves the mill efficiency and pipe qualified rate. This forming method is suitable for large pipe mill (219mm to 711mm), which saves the investment and improves the efficiency.
