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.Welded tube internal surface bead cutting apparatus, chip US20020170940A1 Welded tube manufacturing apparatus Oct 24, 2002In the bead cutting apparatus of the present invention a cutting tool 22 is provided on the distal end of an impeder 21 so as to be able to swing.
