The tooling in the sizing section, in round designs, is designed to oval the tube out of each of the side pass station, and refine it round out of each of the driven stations. It is imperative that this process be set up and maintained throughout the entire sizing section to insure the process of sizing/stress relieving is accomplished.

Conversely, FIGURE B shows improper strip formation for the same tube size, material and mill configuration. The irregular spacing between passes indicates overwork in some passes and underwork in others. Many problems can arise from using this improper design. They include marking of the tube, roll over, buckling, bad welds and incorrect sizing.

adds a fifth roll at the bottom of the tube, allowing smaller diameter side rolls to be used. Many smaller mills use three rolls mounted 120 degrees apart. Some are orientated with a grooved roll at the top of the tube (D), others with a roll directly below the tube. D eliminates edge misalign-ment and is especially suited to D/T ratios above 10:1.
