Experiences in Non- Destructive Examination of Steam Turbine Rotors

摘要

Non-destructive examination is an important means of determining the condition of highly- stressed turbine and generator components during inspections of the turbine generator. Both conventional examination methods (dye penetrant examination, magnetic particle examination, ultrasonic and radiographic examination) as well as part-specific special examination methods are used for non-destructive examination of areas which are subject to particularly high levels of stress (and therefore are especially at risk).
