Figure 2 shows specific pipe identification and characteristics (zone 1); Historical data and batch trends (zone 2); pipe radial illustration (zone 3) and current tube longitudinal wall thickness and eccentricity profiles (zone 4).
Easy-to-interpret visuals deliver valua-
ble information in the blink of an eye. An easy-to-navigate dashboard allows plant operators and managers to quickly access various powerful software features and the information most relevant to them for agile decision-making. Let’s take a look at some of them.
A picture is worth a thousand words:
Lut 2.0 gives operators the complete picture. In the illustration below, Section
A (Thickness/Length in yellow) shows the historical average wall thickness per tube (each dot represents a pipe). We can see that it is quite consistent from pipe to
pipe and well within target throughout the batch. However, Section B (Thickness on roller face) shows that two roll positions have broken away from the pack: the blue line and the green line. These rollers and their relative position are shown in the top right radial illustration (rollers at position R-180 and R-240). We can clearly see that these rollers are applying more pressure on the tube, resulting in a thinner wall at that location. Moreover, this pressure forces some of the material to move in the oppo- site direction, to the gap between adjacent rollers, creating an overfill. In Section C (Thickness on gap), the purple line breaking away from the pack shows that the tube wall is thicker. This overfill and its relative position are clearly detailed in the top right radial illustration, at the gap 360 position.
Powerful real-time knowledge:
Quality information presented in a us- er-friendly format in real time is crucial
in monitoring dynamic processes. Lut 2.0 displays and collects highly accurate data essential for the early detection of trends and potential deviations in wall thickness, eccentricity and polygonization before they become non-compliant. These may be caused by uneven billet heating, piercing tool wear or inaccurate roll-stand settings. Lut 2.0 identifies and tracks sources of devi- ations using a detailed automated analysis for each tube spectrum profile. Each peak in the tube spectrum profile relates to, or points to, a single cause of eccentricity. Lut

Figure 3 – The thickness on roller face graph (Section B) shows that positions R-180 (in blue) and R-240 (in green), the tube wall is thinner relative
to the other roller positions. The thickness on gaps graph (Section C) shows that at position 360 (in purple), the tube wall is thicker relative to the other positions.
