Inspection, Measuring, Testing & Marking
94 March/April 2007
With the successful completion of an order
placed by one of Germany’s leading pipe
mills, Elmed has developed the next level
of the ISO-Automat inline holiday detection
system. The unique combination of the
high-capacity impulse voltage unit and the
sensitive DC module for film and epoxy
coatings enlarges the scope for testing of
corrosion protective coatings.
The new twin line testing electrode
(conductive rubber/brass brush) completes
an effective piece of equipment. The
company can provide a professional
analysis of specific requirements with
flexible implementation based on decades
of experience in high-voltage testing.
With numerous references, Elmed
undertakes continuous development work.
This ensures successful construction
of complete turnkey systems with the
adaptation to international test standards
and specific coating processes. These
processes include side extrusion and
crosshead extrusion and also semi and
fully automatic testing.
The network-compatible industrial PC
checks and documents the parameters of
the modular test system and acts as part of
an individual quality assurance system.

Online non-contact wall
thickness gauge for hot tubes
Tecnar, a world leader in non-contact
thickness gauges, has now made the
LUT gauge available in four different
configurations. The new configurations offer
greater flexibility for installation at several
key locations on a tube mill.
With the fixed configuration, the LUT
gauge is a low-cost solution for on-line
wall thickness measurement, excellent for
monitoring the output of a reeler or rotary
sizer.
In the dual-fixed configuration, the
LUT gauge provides simultaneous wall
thickness measurements along critical
angles of the processing machine. This
enables, for example, real-time feedback
of roller positions. With the scanning
configuration, the LUT gauge gives cross-
sectional information on a tube processing
system with only a linear motion, such as
a reducing mill.
Finally, the LUT gauge is also supplied with
a robotic arm, which is useful when the
probe must be removed from the production
