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.

A standard fin blade works the entire strip edge and prepares it for welding. A straight fin or one with altered angles is used to work the inside edges of the strip to reduce the I.D. bead. Special attention must be used in setup to avoid having a cold I.D. weld and possible cracks. A round fin pass design is most recommended unless the mill ...

Tube mills produce pipe and tube by taking a continuous strip of material and continuously roll forms it until the edges of the strip meet together at a weld station. At this point, the welding process melts and fuses the edges of the tube together and the material exits the weld station as welded tube. Basic components include an uncoiler ...

Weld Roll Configuration (C): This configuration of four (4) rolls, (two (2) bottoms & two (2) tops), are normally found on larger tube/pipe mills from 3.000" O.D. and up, with wall thickness of .250" and above using High Frequency (HF) "coil and contact" welding. These four (4) roll weld boxes are normally very robust in design and integrity ...
