Definition of a Changeover for Tube and Pipe Mills | Roll-Kraft
On "M" style mills, using solid tooling, the metal line drops, thus requiring the side roll passes to be lowered to match the new metal line. Part of a good tooling maintenance and set-up program, is knowing exactly how much to drop or raise the metal line of different roll sets at the time of set-up, not to just guess at their height.
Tips for maximizing tube, pipe mill efficiency (Part I)
Roll tooling suppliers vary, the ways they work the tube vary, and therefore their products vary. The yield also varies. "The surface of a roll has a continuously changing radius, so the rotational velocity of the tooling varies over the face of the tool," he said. The tube moves through the mill at just one velocity, of course.

Welded roll forming system versus tube mills: What's the …
In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been fine-tuned to run a specific diameter range, typically at fast speeds (see Figure 1 ). Diameter range is mentioned because a tube mill welds a round product.
