Design phase
During the eleven-month developmenttime,
the project participants of both companies
worked closely together. Siempelkamp
contributed the know-how from a
number of similar projects and EUROPIPE
contributed with its experience from
operating pipeline manufacturing lines.
Because of the large technical experience
of the Siempelkamp engineers, EUROPIPE
gave them a lot of freedom during the
design process. During routine meetings,
mainly the integration of the new press in
the available space and the transport of
components with weights up to 216 t (238
US tons) all the way into the production
hall were discussed.
the blueprints of the old foundation could
be provided by EUROPIPE so that structural
engineers only had to check whether the
existing foundation would be suitable for
the new press.

the new press, just as the old one, is
expected to operate for many decades.
Siempelkamp used the finite element
method to prove the fatigue strength of
the main components including the frame,
the moving beam, and the foundation
stands.
Both parties will confirm that the partnership
at eye level was the base for the
project’s success. this success would not
have been possible without the high qualification
and the experiences in dealing
with extraordinary large presses on both
sides as well as realistic demands.
Exactly on schedule
After the castings, made in Siempelkamp’s
own foundry, were completed and the
press was assembled by Siempelkamp in
Krefeld, the functional test and performance
tests were carried out. they progressed
successfully so that EUROPIPE was

able to commence with the disassembly of
the old press as scheduled. the disassembly
of the old machine took almost two
weeks. In only five weeks, Siempelkamp
assembled and started up the new press.
the edges of the first plate were bent on
August 18, 2008 – on the scheduled date.
Already the first plate was according to
specifications and was made into a saleable
pipe. Since August 2008 the press produced
continuously in two-shift operation.
Siempelkamp specialists monitored the
start-up on site for three months. One employee
stayed until January 2009, but did
not have to get involved anymore at the
end of his time.
the first plates were bent by manual
operation. Already after three days the
press was operating in automatic mode
for individual plates, after a week for
several plates in series. Regular material
flow was achieved after two to three
