In-service inspection of turbine rotors
requires dismantling of rotors. A combination of an Ultrasonic
Phased Array system with a small magnetic scanner allows the
inspection of rotors after opening of the turbine housing.
The inspection is performed from the narrow lanes between
the turbine discs / blades. Considerable timesavings can be
achieved using this system. Results of the Phased Array inspection
of turbine rotors are presented along with operation experience
with the new magnetic scanner.
