Wall thickness measurement for hot seamless tube and pipe mills

Tecnar has over 20 years of experience implementing non-contact ultrasonic thickness gauges in hot seamless tube mills. The Lut 2.0 is engineered to provide the most accurate wall thickness information in a robust, low-maintenance package.

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.

Laser ultrasonics technology

The only technique to provide true, direct wall thickness measurements.

Proprietary hardware

The Lut 2.0 core units are built around Tecnar’s proprietary designs and engineered to achieve one goal: bulletproof reliability.

User friendly software

The Lut 2.0 is equipped with a web-based user interface and a SQL database that can be accessed from anywhere in the plant.
