Examining tube mill roll tooling, setup, and maintenance
3. Length minimum and maximum. 4. Notching or secondary operations. 5. Reference to mating parts. 6. Attention to critical areas. If a worn-out sample roll is submitted instead of a roll drawing, the manufacturer should take the time to reverse-engineer the roll, make a new drawing, and get it approved by the customer to avoid …
Custom Tube Mill & Pipe Mill Machine | Roll Forming …
Tube Mill: A tube mill is a machine used to manufacture round or square tubes from flat metal strips or coils. The process typically involves the following steps: a. Uncoiling: The metal coil is unwound and fed into the tube mill. b. Forming: Roll forming stands or rolls shape the flat metal into a cylindrical or square shape. c.

Coil joining criteria for tube and pipe mills
Gas metal arc welding (GMAW) is the next most commonly used technique in tube and pipe mills. It operates successfully in 0.055- to 0.500-in. gauges or thicker. Because GMAW wire is driven into the weld seam and becomes a part of the nugget, buildups of 10 percent or so can be expected. However, GMAW speeds are 25 to 50 IPM.
Wall thickness measurement for hot seamless tube and pipe mills
The Lut 2.0 thickness gauge continuously monitors production and helps operators ensure that the mill is operating at full capacity. Avoid loss when rolling a high-tolerance short production lot in which every piece needs to be perfect. Monitor slow drifts in the tube characteristics during long production runs caused by wear in the mill.

Achieving faster, more efficient tube mill changeovers
Tube mill changeovers involved more than just tooling. Fast changeovers require control over many variables (entry equipment, side pass stands, and so on). ... The weld rolls should be set up with a plug gauge of the same diameter as the welded tube size to match the radius of the weld rolls. This is especially effective in three- and four …

Best practices for roll form tooling maintenance
The resources used for a setup, time and material, should be consistent and predictable from one setup to the next. Another best practice is to clean the rolls and inspect them every time they are removed from the mill. Use profile gauges to measure the amount of wear on the working surfaces (see Figure 1 ).

Do a progressive set up. This means jog the material through the first driven breakdown, through the first 1-2 side roll pass, (if your mill configuration has side passes) and into the second driven breakdown, then stop. Many firms jog the material all the way through the entire mill before starting any set up checks.

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.
