Linear cage forming for
stainless steel from Italy
OLIMPIA 80 has specialised for over 40
years in engineering and manufacturing
a wide range of tube mills for carbon
steel, stainless steel, titanium and non-
ferrous materials to produce round,
square, rectangular and special profiles.
The company can also supply turnkey
systems, find custom-made solutions,
offer suggestions to upgrade old
systems, and provide a complete after-
sales technical and personnel training
service. The company can propose the
innovative and patented technology
named Linear Cage Forming, in two
different solutions: for round tubes; and
for square and rectangular tubes.
The Linear Cage Forming system is
the result of many years of experience
and knowledge in the tube field. This
method brings advantages in terms
of flexibility, production capability
and production cost reduction. The
innovation consists in the possibility to
produce any tube in any size, included
into the mill range, without roll change
and in few minutes with an extreme
reduction in set up time.
The tube forming system, developed
and realised by Olimpia 80, makes use
of the latest technologies which allow the
user to vary the diameters of the tubes
to be produced without any changing
of the rolls. The compact system
consists of 11 sequential stations,
eight of which operate as breakdowns
and three operating as finpasses. This
combination allows a final and complete
closure of the tube before the welding.
The 86 independent axles, operated
by computerised servomotors and
an easy-to-use operating interface
system, help to reach in a quick and
simple way the optimal position for the
correct tube forming. Strip feeding is
assured by a system of independent
pinch-rolls, which are installed on the
first six stands.
The main advantages of the system
are adjustment flexibility; automatic
change of tubeODand gauge; significant
change over time savings; tool cost
reduction for round
tubes; labour
cost reduction;
and easier and faster maintenance.
The Linear Cage Forming for square
and rectangular tubes, developed and
patented by Olimpia 80, can carry out
the forming change operation in a very
short time and without any replacement
of rolls. The system is applied to any
part of the production line: forming,
welding, sizing or straightening.
The line set up is, as a result, totally
automatic.
The square or rectangular shaping
is directly carried out before the tube
welding, with important advantages
in terms of power and material cost
reduction.
Olimpia 80 has put into operation tube
mills with this technology in Germany,
Turkey, Italy and USA.

Welded pipes
added to
Stellar range
SINCE it was founded, Stellar Tube & Pipe Group has been
dedicated to high quality stainless steel seamless tube and
pipe manufacturing, and has taken a vital role in the industry.
In order to satisfy customers’ needs, Stellar joined with
Irestal Group of Spain, to set up the joint venture Irestal
(Shanghai) Stainless Pipe Co, Ltd, which professionally
manufactures welded pipes. The total investment in the plant
is around US$45mn. Its designed annual capacity is around
30,000 tonnes, with continuous process lines, the OD can
range from 10 to 219mm, WT 0.5 to 8mm; while with bending
process lines, OD range is 273 to 2,500mm, WT 3 to 25mm.
All key machines and testing facilities are imported from
leading European manufacturers.
