Multichannel tube wall thickness
measuring system for PQF mill
Vallourec & Sumitomo Tubos do Brasil Ltda (VSB) has contracted IMS Messsysteme
GmbH to deliver a multichannel tube wall thickness measuring system. This system,
to be installed behind the PQF extractor mill, will be used to measure tube shells at the
exit of its SMS Meer PQF mill.
In addition to the estab-
lished 13-channel measuring
geometry for PQF mills,
which is used for continuous
measurement of polygonal
wall distributions, the
measuring system will
be equipped with a high-
resolution diameter gauge. A
total of 18 laser triangulation
sensors will be fitted, which
will enable accurate detection
of out-of-round flaws and
profiling of the tube outside
diameter.
The laser-based measuring technology, integrated for the first time in an IMS tube wall
thickness measuring system, has already been used successfully for several years at
Ovako Steel AB, Sweden, as a standalone measuring system. The sensor and analysis
systems are now being integrated in the IMS measuring system in close cooperation
with the company LIMAB.
The system can simultaneously measure the wall thickness and eccentricity, outside
diameter and profile, temperature and length of tubes in a single compact gauge,
avoiding the need to install multiple individual systems.

From hacksaws
to bandsaws
The Hermann Klaeger Company, Germany,
is the manufacturer of hacksaw machines,
pipe bending machines, and bandsaw
machines. Established in 1928, the
company has sold over 135,000 machines
to date.
The company’s range includes band saws
with a capacity from Ø 220 to 325mm round,
fully automatic bandsaws, fully automatic
twin-pillar bandsaws, vertical bandsaw
machines, hacksaws (capacity from Ø 200
to 315mm round), ring rollers (universal
bending machine, capacity pipe maximum
Ø 70), and press benders for pipes up to 2"
(available in hydraulic and electro hydraulic
versions).
The company sells its machines both to
dealers and directly to the end user, and its
products are specified in the catalogues of
well-known dealers in Germany and other
countries.

PMC-Colinet, a division of Ajax Tocco
Magnethermic Corp, is the manufacturer
of advanced coupling starter and screw-on
machine systems for secure connections in
the oilfield. Designed for API and premium
connections, these systems use floating
spindles to automatically and precisely
fit a coupling onto a pipe end for OCTG
applications.
The systems have a high-powered motor
to screw the coupling on securely, applying
and recording the right torque. These
systems save time, labour and expense in
the customer’s application by giving a tight
and precise pipe-to-coupling fit – a must for
productive execution in the field.
The coupling starter and screw-on
machines assure connections for pipe sizes
ranging from 1.9" up to 20". The systems
are equipped to measure and control
torque, turns, stand-off and ‘J’ dimension
metrics. Accompanying operator interface
terminals display and store final values and
graphical profiles, using PC-based Windows
operating systems.
Other technical features include a coupling
starter, independently controlled spindle
speed, and a hydraulically actuated gripper
head and pipe chuck. The coupling screw-
on has a variable spindle speed, 75kW
(100hp) spindle motor power, and a make-
up torque of up to 35,000ft-lbs.
The starter and screw-on systems are
among the dozens of pipe-processing
systems manufactured by PMC-Colinet.
PMC-Colinet’s parent company, Ajax Tocco
Magnethermic, is a leading worldwide
designer and builder of heating, melting
and processing equipment for pipe
applications.
Specialities include quench and temper
lines, annealing furnaces, and heat treat-
ment solutions for seams and welds.
