LAP GmbH, Germany, has introduced a
new, robotized laser measurement system
that provides 100 per cent quality control
of tube end dimensions compliant with API
requirements. This system enables precise
measured data for each individual tube in the
finishing shop and during tube inspection.
Tube end rectangularity and welding bevel
measurements can be included as optional
features. Inline measurement by laser
triangulation sensors dispenses with the
manual offline random checks, which were
common in the past.
The
measurement
system is designed for
tube diameters from
168mm to 1,500mm.
The accuracy of the
diameter
measure-
ment is between
0.1mm and 0.3mm
depending on the
measurement range.
The company has
also developed Calix,
a new laser-based
thickness
sensor
that measures strip
thickness inline. The
Calix system carries
out
measurements
independently of the
material properties.
For the user this often means that
it is unnecessary to input material
parameters and maintain the material
data in a database, as required by
radiometric
gauge
measurements.
In addition, there is no handling of
radioactive material.
Due to its novel design, Calix requires
no calibration onsite, either when it
is first installed or during operation.
Even optically challenging surfaces
like black varnished, glossy sheet can
be measured by Calix with accuracies
better than ±5µm under production
conditions.
The system is highly compact: it is no
longer necessary to design complex
measuring bridges. All it needs is the
single compact, easy to install C-frame,
which can simply be traversed across the
width of the material.
The new RDMS-40 profile measuring
system for inline profile measurements
has been specially developed for wire
rod mills operating at speeds of up
to 150m/s. It rounds off LAP’s range
of measurement systems for long
products.
Using the novel series of Metis laser
micrometers designed by LAP, the
company now offers measurement
solutions for all diameters between a few
millimetres and more than one metre.

With the new laser based system it is possible for the first time to have
precise measured data at hand for each individual tube in the finishing shop
