LIMAB, Sweden, manufactures laser
measurement systems for the steel industry
and is a pioneer in non-contact laser
measurement, with sensor development,
engineering, design and manufacturing all
done in-house. It has developed several
measurement solutions for the steel
industry such as diameter, ovality, length,
thickness and width measurement.
The company presents two different
key systems for diameter and ovality/
shape measurement: HotProfiler
and Tubeprofiler. HotProfiler is a non-
contact laser measuring system for hot
and cold applications in bar and tube
rolling mills. The system can be equipped
with 18 sensors placed in an oscillating
measurement frame. Tubeprofiler is a non-
oscillating measurement system, equipped
with up to 18 sensors, for hot and cold
applications in bar, tube and pipe mills.
The system can easily measure on
round, square, hexagonal, flat or any
other type of tubes. The unique design of
measuring using distance sensors mounted
around the tube will detect any type of
shape error, which means that there are no
blind zones. All measured dimensions are
processed and displayed in the operator
software. The results are shown as real-
time numbers, trend graphs as well as in
2D and 3D graphs for easy viewing. The
database provides an excellent source of
production data for long-term monitoring
and process improvements and will output
key dimensions and alarm signals if any
of the tolerance or warning limits are
exceeded.
The Hotprofiler and the TubeProfiler
are very easy to install in the existing line
and easy to relocate to other parts of the
mill, using the built-in lifting hooks and
the quick change electrical connectors.
The core part of the system is the laser
sensor itself, which has no moving parts
for zero maintenance. The sensors are
completely sealed with digital processor
inside and capable of withstanding hot and
dirty industrial environments.

True tube profile measurement system Solution for
cleaning inside
of tubes and pipes
TUBE Clean GmbH is a Swiss manufacturer
and distributor of equipment for hose, tube
and pipe cleaning, providing complete and
fully integrated solutions.
The company states that the Bison
4000 W/D is the first plant available in
the industry that allows a combined wet
and dry cleaning of tubes and pipes. The
machine can clean inside diameters from
1.8 to 32mm, and the company claims
it is fast (intervals of two seconds) and
environmentally friendly.
All necessary parameters are fed
into the system via a touch-screen. The
modular design allows for customer-
specific solutions or integration into existing
processing lines.
