Macedonian producer of steel welded
pipes, IGM Trade, has expanded its
range of steel welded pipes. The
company’s new pipe line can produce
squarepipes up to 250x250x12mm and
rectangularpipesup to300x200x12mm,
increasing the capacity of the factory to
250,000tperyear.Thecompanyhasalso
invested innewslitting
slitting line, and one to accommodate
widths of 2,000mm, thickness of 16mm
and lengths of 15m.
Theownerof the factory,Mr IlijaGechev,
said that IGM Trade is the largest
green-field investment in South East
Europe,with an area of 400,000m2 and
covered space in buildings and halls of
Blue Ridge Numerics, Inc, a leader in
upfront CFD software, has announced
that CFdesign 2010 has been fully
tested and is compatiblewithMicrosoft
Windows 7. The process ensures that
CFdesign 2010 has passed Microsoft-
designedtestsforcompatibility,reliability
and performance on the Windows 7
platform, using both 32- and 64-bit
processors.CFdesign isalsocompatible
withWindows XP andWindows Vista.
“We are committed to leveraging and
supporting the latest and greatest
150,000m2. The company’s next goal is
to invest in a cold rollingmill.
The production programme of IGM
Trade also includes round pipes up
to 168.3x6mm, tested pipes under
pressure of 50 bar up to 88.9x4mm,
oval pipes andRP profiles.
The company supplies around 10% of
its pipes to the domestic market, and
exports 90% to the EU and Balkan
markets.Production iscertifiedwith ISO
9001 andCE-mark.

commented Derrek Cooper, product
manager,BlueRidgeNumerics.
“It is very important that our customers
are able to keep their equipment and
operating systems up-to-date and be
assured that CFdesign will ‘just work’
on new versi
platform.”
In addition, CFdesign 2010 supports
the new Core i7 processor from Intel,
providing users with up to 2.5 times
faster processing times than with
earlier processors. CFdesign upfront
CFD software integrates compre-
hensive fluid-flow and heat-transfer
simulation into early phases of design
and engineering, when companies can
improveproductquality, time-to-market,
and ultimately profitability through the
product life cycle.

Steelproducts fromTurkey
Hasçelik, amanufacturer and importer of steel products, holds stock of approximately 50,000 tons in six warehouses, to
meet urgent requirements.
In thecompany’scontinuoushot-rollingmill located inKocaeli,Turkey,hot rolled round, flat, squareandhexagonal steelbars
are produced,with a capacity of 200,000 tons per year.Hasçelik also produces cold drawn, peeled and ground steel round
bars, aswell as square, hexagonal, and flat bars in two service centres located in Istanbul andKonya.
The company’s product range consists of hot-rolled steel bars (round, flat, square and hexagonal), cold drawn bright steel
bars (round, flat, square and hexagonal), and peeled or ground bright steel round bars.Main grades are S235JR, St37.2,
S355JR,St52.3,C10,C20,C30,C40,Ck45,C60,SAE1010,SAE1020,SAE1030,SAE1040,SAE1045,SAE1050,55CR3 and
60SIMN5.
Besides production, Hasçelik imports special steel bars and seamless steel tubes from leading producers. Such products
include hot rolled round bars, forged round bars, forged square bars, hot rolled flat bars, seamless steel tubes and ground
round bars.

Tailored Orbitals
® from ThyssenKrupp
Tailored Blanks feature a function-
and load-oriented structure precisely
matched to the conditions in the part.
Unlike other tailored products, they are
made from tubular starting material,
rather than from flat blanks.
The rotationally symmetrical parts are
manufactured on a dedicated laser
welding line,onwhichuptofive individual
tube segments can be joined together
end-on. The individual segments can
consist of different materials such as
carbon steel and stainless steel, and
can have different diameters, different
wall thicknesses and different coatings.
The result is a starting material that is
optimised from theoutset foraparticular
application.
Typical areas of use for TailoredOrbitals
include car seats, exhaust systems,
cockpit support tubes and chassis
parts. For example, ThyssenKrupp
TailoredBlankshasdevelopeda tailored
orbital alternative for a rear seat back
reinforcementmade fromaconventional
tube. The new solution reduces weight
by around a kilogram because the
conventional structure is made from
a tube of uniform wall thickness, that
thickness being determined by the
highest loads occurring in the part. The
partmade from a tailored orbital on the
othr hand is of varyingwall thickness.
In the lower thirdof th seatback,where
the heaviest loads occur, thematerial is
1.5 to 2.5mm thick. In the other areas,
1 t 1.5mm is sufficient.
Tailored Orbitals for shock absorber
reservoir tubes achieve claimed weight
reductionsofup to30%.ThyssenKrupp
Tailored Blanks has
eveloped a new
solution for a currentmid-size platform.
Unlike the conventional solution, with
uniform wall thickness, the Tailored
Orbitals solution has a thickness of
around2.5mmonly in thehighlystressed
lower section of the tube. Further up,
wall thicknesses ofwell below 2mm are
sufficient.
In view of the high cost of the stainless
steel used in exhausts, wall thickness
reductions have a large impact in the
shapeof reducedmaterialcosts.Further
savings opportunities are offered by the
ability to combine different materials.
The use of expensive, highly corrosion–
resistant materials can be limited to
areas exposed to particular attack
from heat and aggressive exhaust gas
constituents.
Tailored Obitals can be fabricated just
like conventional straight-seam welded
tubes.Theorbitalsdonothave tobe cut
to length first,because this ispart of the
manufacturing process, as ismachining
of the tubeends.Dimensional tolerances
are similar to those of straight-seam
weldedtubes.Inaddition,TailoredOrbitals
can shorten production processes by
combining severalmanufacturing steps.
The orbitals are available in lengths of
up to 2,500mm, and in diameters that
can vary between 30 and 90mmwithin
one tube. They can be made in all
carbon and stainless steels suitable for
laserwelding.
