Before pipe welding, pipe is formed in
round shape passing through a series of driven and idler rollers of
forming section. In welding section pipe is longitudinally welded by
using high frequency induction welding method. Outside bead is removed
and formed in shape of scrap. The weld seam is ironed and pipe passes
through the cooling section.Nota:(1)I valori nella tabella sono adatti per il campione standard a grandezza naturale.
