Rotor, casings, fuel nozzles and weld repairs can often be carried out during a major overhaul directly on-site.
Some of the critical areas that are examined include compressor blades, rotor journal and turbine wheel conditions. In addition, NDT blades and dovetails, blade migration and balance weight locations are all inspected to the OEM’s specifications. A review of Bulletins and Technical Information Letters (TILs) are also completed to ensure up to date compliance.
A compressor component’s anti-corrosion and increased efficiency coating, WG-50, is Sermatel 5380DP equivalent and can be applied to the individual components or to the assembled rotor. Additionally, turbine section anti-corrosion coatings and bucket anti-rock can be applied to the wheel/ buckets, individual components or the assembled rotor.
