With versatile productivity at their heart, tube
mills and rollforming lines are the lifeblood of
the tube and pipe industry. Based on the skilful
orchestration of rolls that form strip into high
quality products, it is increasingly essential for
the tube mill operator to focus on mill alignment
and roll tooling setup. With fast changeover and
dual capability now even higher on the agenda,
mills and rollforming lines are also finding greater
occupation in the duties of continuous operation
– cut-to-length, punching and notching.

Focus on Tube & Pipe Mills
and Rollforming Lines
As in the natural world, protection for
manufactured products is of great importance if
corrosive attacks are to be repelled and wear
and tear prevented. Sometimes defence is
the best form of offence – crushing resistance
with state-of-the-art protection; tube and pipe
is subjected to a rigorous process in order to
withstand a lifetime of hardship. This arsenal
of technology includes continuous induction
annealing, acid pickling, intensive heat
treatment, and UV-curable coatings.
