Setting up the Fin Section
The primary job of the fin section on any tube or pipe mill is to prepare the edges of the strip (parallel) for welding, and set the body of the tube. The only way this will take place, is if we properly set (work) each and every driven and side pass station in the fin section as per the tooling design and set up chart.
Solving problems on the tube mill
