Stud tensioning machines
Stud tensioning machines in 2009 – eight completed
projects, nine new orders
The milestones in 2009 in the area of stud tensioning machines
included the completion of two projects for the French plant
operator EDF. Next to upgrading a plant we supplied new stud
tensioners for which a new technical concept was predominant.
Instead of using a massive support ring made of forged steel, we
designed this component group in sandwich construction. This
ring is equipped with a total of 58 assembled tensioning units
and has to withstand a pressure of up to 2,000 bar.
Further component deliveries that went to the Czech Republic,
China and Russia as well as the completion of a modifi cation
project in South Korea show how well-positioned our company
is in this market niche.
Despite partly drawn-out decision processes which were intensifi
ed by the global fi nancial crisis, the ambitious plans for new
constructions and equipment upgrades in many countries resulted
in a successful total order quantity for us in 2009. Noteworthy is
an order from France for the supply of a new stud tensioning
machine and the upgrading of eight plants. The order was topped
off by a ten-year service contract for the equipment of the French
producer.
Our hydraulic stud tensioning machines for the opening and closing of reactor
pressure vessels have been used throughout the world for almost 40 years. Next to
stud tensioning machines, which have a high degree of automation, our many
years of experience are also used for the development of customer-specifi c
solutions. In this area, we score with concept development and design engineering,
production and delivery including the start-up at the plant and, if desired, ongoing
support in the scope of service orders. Equipment and special tools complementing
the use of stud tensioning machines have an increasing demand.
