Welded roll forming system versus tube mills: …

Forming some shapes on the tube mill simply isn’t possible, but a welded roll forming mill can form highly complicated shapes quite readily. Also consider the outside corner radii of those shapes. In some cases, a tube mill can form those radii down to 2 times the material thickness, but this isn’t typical. Usually a tube mill can form ...

The mandrel mill shell is then reheated in a reheat furnace so that it can complete the final rolling process and gain its final dimensions and micro-structural qualities. Upon exit from the reheat furnace, the tube receives a high-pressure water descale, removing the iron oxide scale that formed in the reheat furnace. A clean, scale-free surface is critical for good surface quality.
