Press releases
The new Lut 2.0 Dual Probe Scanning (DPS)
has been installed at the exit of the extrac-
tor mill on an SMS PQF® (Premium Quality
Finishing) line. In this configuration, two
probes move rapidly back and forth across
the tube to scan the wall thickness at the
mill exit. Successive scans build a high-res-
olution circumferential profile of the wall
thickness as the tube advances, allowing
operators to easily detect any roll misalign-
ment or setting deviations within the PQF
mill. Lut 2.0’s accuracy and scanning speed
make it ideally suited to capture the com-
plex circumferential thickness variations
typical of three-roll mills, providing a direct
path to improved process control and yield
stability.
This installation also marks the first intro-
duction of Tecnar’s Digital Twin technology
into a production environment. The Digital
Twin is an advanced post-processing of
the data acquired from the Lut 2.0 sen-
sors, providing enhanced visualization of
both average and min–max wall-thickness
profiles. This powerful analytical layer gives
operators a clearer understanding of pro-
cess trends and enables more responsive
mill adjustments. Together, Lut 2.0 and its
Digital Twin interface set a new benchmark
for real-time process monitoring and yield
improvement in tube manufacturing.
At the core of Lut 2.0 is Tecnar’s proprietary
laser-ultrasonic technology, a non-contact
ultrasonic measurement technique. In this
approach, a pulsed laser generates ultra-
sonic waves on the tube surface, while a
38
second laser detects the resulting vibra-
tions without any physical coupling. By
accurately measuring the propagation time
of these ultrasonic waves through the tube
wall, Lut 2.0 provides direct and absolute
wall-thickness measurements that remain
unaffected by temperature variations, tube
motion or vibration, and the presence of
a mandrel inside the tube—significantly
expanding the range of positions along the
mill where reliable online thickness mon-
itoring can be performed. This makes la-
ser-ultrasonic technology the most reliable
and versatile method for online wall-thick-
ness measurement in hot tube and pipe
processes, seamless and welded.
