Synergy for turnkey tube
manufacturing
FASPAR, a specialist in coil processing
equipment, and Olimpia 80, an expert
in systems and equipment for welded
tubes, have shared their experience
and core business to ensure the quality
of strip products at the entry of tube
mills.
This operation can be underestimated,
but it is important in order to fully exploit
the capacity of the tube mill.
Faspar has been a producer of
turnkey equipment for the processing of
metal coils since 1966.
Its main product range includes slitting
lines; levelling, straightening and cut-to-
length lines (with feeder, rotary shear
or flying shear); surface finishing lines;
feeding and pressing/punching/bending
lines; and tension/stretch levelling
lines.
Olimpia 80 Srl has specialised in
the engineering and manufacture of
systems and equipment for welded
tubes since 1980.
The main product range of Olimpia
80 consists of complete tube mills and
components.
Faspar and Olimpia 80 recently put
into operation one slitting line and two
tube mills, positioned side by side, in
a Ukrainian plant of one of the world’s
largest titanium producers. The final
use of these titanium tubes is in
the energy field (nuclear) and heat
exchangers.
The Faspar slitting lines can process
grade 1 and 2 coils, VT1-0 up to 10 tons,
at line speeds up to 200m/min, and in
thickness from 0.4 to 2.5mm, in order
to produce strips with width from 35 to
200mm, suitable for the tube mill lines
and final output tube diameter.
Olimpia 80 tube mills lines can process
tubes with outside diameters from 12
to 60.3mm, and thickness from 0.4 to
2.5mm, welded with a TIG system. The
final tube length is from 4 to 26m.

Faspar and Olimpia lines and final products
Straightening of oil and gas tubes
TUBES, square bars and profiles, which
were previously straightened almost
exclusively through the rolling process
or by simple manual presses, can now
be precision straightened to ensure tight
linearity tolerances.
Heavy-duty automatic straightening
machines have improved through
the use of sophisticated kinematics,
actuators and electronics. Applications
in fields such as energy, oil and gas, steel
mills and hydraulics require processes
that guarantee high quality finished
products. For example, in the oil and
gas and nuclear fields the increasingly
stringent international API guidelines
and recent events have made quality
standards of pipes for these applications
among the most rigorous in the world.
The Galdabini Gantry heavy-duty
machine is designed for straightening
long raw tubes and bars, forged or
finished. Workpiece measurement takes
place by continuous scanning (laser),
which allows reading and reconstruction
of the actual deformation curve.
Fully automatic straightening is fast
and optimises machine parameters,
in addition to controlling workpiece
deformation (absolute and linearity
error).
The advantage of this process
is the straightness results over the
entire length, certified and repeatable
measurements and high productivity of
the system, especially when operating
24 hours a day, equipped with loading/
unloading units.
The aim of reducing longitudinal
dimensions to the minimum is achieved,
maintaining machine frame stability
and flexibility of use. The machine is
electromechanically or hydraulically
controlled, depending on the tonnage.
Measuring before and after
straightening allows full traceability of
the product, with an important impact
on the quality of the production cycle.
Easy maintenance is assured by
diagnosis and maintenance messenger
systems for the remote control of
customer service.
