The High frequency straight seam welded pipe mill 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.

Technical Process:
