MARC Steam Turbines The Modular Steam Turbine Generation

Quality Assurance
The most important principle of turbine
manufacture is to ensure high quality
standards for all components. The
turbines are subjected to the following
checks during the manufacturing
process.
18
Material inspections
Castings inspection
Production inspection
Assembly inspection
Continuous quality control is ensured
by the ISO 9001 quality management
system.The turbine and baseframe are
erected and the internal piping is installed
on the assembly bed. The gearing/generator
modular unit is assembled
at the generator manufacturer and
subjected to a functional check. As with
the other modules, both oil modules are
tested at the manufacturer prior to their
installation adjacent to the turbine on
site.
In order to meet the requirements for
quiet running, operational safety and
high availability of the steam turbines,
each turbine rotor is subjected to highspeed
dynamic balancing and spin
testing in a vacuum spin test facility.
After this acceptance test the rotor can
be installed.
