Slited coil is uncoiled
and feed into forming section passing through the equipment of
entry section. Entry section enables tube mill to run continuously
by using strip joining and accumulator. Before 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.
Then in sizing section, pipe is formed to specified size and
converted into specified shape. After sizing, pipe is cut to
required length by using flying saw cut off equipment and delivered
to collecting table after passing through run out
