Welded tube and profile lines
BIRLIK Makina has more than 22 years’
experience in designing, manufacturing
and installing complete systems for the
production of welded tube and/or profile
lines and has more than 120 employees.
The company has highly trained
technical personnel and top-level
facilities with its own tube manufacturing
factories in Turkey and Azerbaijan
meaning it can offer its long-term
experience about which machine best
suits each customer. It also trains
specialist operators at its factories
in order to send them to customers’
factories to support productivity.
Birlik Makina had a steady increase
in sales in foreign markets last year and
exported to more than 30 countries. In
total it has manufactured two hundred
lines worldwide. It advises customers
in all aspects of the tube manufacturing
process, such as choosing optimum
machinery for their markets, projecting
their plants, supplying required cranes,
projects for oil and water tanks,
packaging solutions, welding systems,
ferrite core applications and production
organisation.

Processing of high-strength pipes
THE step-by-step shaping of a tube
end or a tube has been made possible
by a newly developed procedure for
processing high-strength and ultra-
high-strength materials. This could
revolutionise manufacturing, particularly
in industrial applications where the
requirements are set ever higher,
and straight tubes are formed into
increasingly extreme shapes.
Incremental tube shaping can be used
for weight reduction purposes in the
automotive industry, for example. A wide
variety of products manufactured with
this new type of process can be exposed
to heavier loads and are lighter.
The innovation of incremental tube
forming has arisen from cooperation
between transfluid Maschinenbau GmbH
and the Institute of Forming Technology
And Lightweight Construction at
Dortmund’s Technical University.
“Conventional forming processes are
over-taxed with the majority of high-
strength materials,” stated transfluid
managing director Gerd Nöker. “Our
machine can partially shape tube made
of such materials, in order to prepare
them for the next process.”
Hydroforming, for example, could
be such a subsequent process. For
this, a tube is pre-formed with different
diameters and different wall thicknesses
by means of the incremental shaping
forming. Particularly important for
hydroforming is that there is no change
in wall thickness in the locally reduced
tube area. High-strength and ultra-high-
strength materials can be cold shaped.
Bending radii and free-form radii can
be shaped in a continuous process with
high accuracy and without spring-back.
The rolling process also allows a
defined manipulation of the surface. The
tube forming machine from transfluid
is equipped with a simple bending
device. The shaped tube is bent with
very little force being required. The
rotatory shaping brings the material to
the plasticising zone, and tubes can
be simultaneously bent with relatively
tight radii without mandrels. Because
the tube spring-back is minimal due to
the plasticised material, the bending
angle achieved is almost identical to the
selected angle of the bending machine.
