Getting the most for your money

When the time came to replace their aging gamma-ray thickness gauges installed on tube mill 4 & 5, Ovako selected the Lut 2.0 as their new standard for online thickness monitoring. Taking advantage of their cross rolling sizing mill, Ovako installed the Lut 2.0 SPF at the last step of the manufacturing process, enabling them to achieve full cross-sectional wall thickness measurement coverage and highly accurate eccentricity monitoring with a single probe.

Safer work environment

by replacing gamma-ray based gauges with Lut 2.0 units

Accurate eccentricity monitoring

by taking advantage of cross rolling processes to get full surface coverage

Accurate thickness profile

vital for tube mills with short production lots and hundreds of product sizes

Tight wall tolerance

Ovako is a world leader with its very tight tolerances across the entire size range, both in outer diameter and wall thickness, as well as other parameters, such as straightness and ovality. In practice, this means less machining and better yield for their customers, resulting in lower component production costs. The key to attaining these high tolerances is the Lut 2.0’s highly accurate online thickness monitoring during the hot rolling process.
