Why get a thickness gauge?

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.

Reduce mill set-up time by 180h/year

See the impact of rolling parameter changes as soon as the first tube leaves the mill. Quickly attain tolerance, especially during size changes.

Increase yield up to 5%

By constantly monitoring the tube wall thickness, operators can track tool wear and slow process drift as they develop, helping them to react before the tubes are out of tolerance.

Thickness variation <7%

Set tighter tolerance on wall thickness and reduce end length and eccentricity. Use less material and roll better-quality tubes.

Reduce losses >10,000t/year

Use the Lut 2.0 wall thickness profile to increase overall yield by minimizing the length of the heavy ends.

Real-time monitoring

The Lut 2.0 fully automated measurement sequence easily integrates into your existing automation system for a fully seamless operation.

Safer work environment

The Lut 2.0 automates manual thickness sampling so operators can work more safely and efficiently.

Discover the innovations behind the Lut 2.0

The Lut is the first technology that provides true wall thickness measurement online with micron-level accuracy.

In addition, it is the only gauge that fully characterizes eccentricity under all plant conditions.
