ERW steel pipe production line: At first, the coil is loaded at the uncoiler, then but-welding the ends of coil, delivering to accumulator. After accumulator, the strip is pulled from accumulator contentiously by fixed speed, is formed to opened-pipe at forming machine, then welded by High frequency welder, deburred, cooled, shaped and sized as round pipe and rectangular&square pipe at the sizing area. Then the sized pipe is straightened after Turkey-head device and then cutt to fixed length by flying saw.
This ERW Pipe making machines is used to level the fixed strip after slitting line, and entry it to forming machine, bend to pipe by roller, melt the strip edges through the High frequency current, squeeze and weld the pipe by the squeeze roll. The high frequency pipe mill is also called ERW pipe mill.
