The coils are picked up from the storehouse and longitudinally cut by an appropriate slitting line,
in order to obtain strips with a width corresponding to the circumference of the tubes to be produced.
Once cut, the strips are inserted into the different tube forming lines, where they take a
circular shape through driven and idle rolls, and then longitudinally TIG or Laser welded.
The tubes are successively scarfed, sized, brushed, marked and cut in 6m-length .
Some further available processing may include pickling, polishing and mirror-polishing.
