Reliability of turbine-generators is critical for fossil and combined cycle power production.
Structural Integrity Associates, Inc. (SI) provides comprehensive turbine and generator inspection and life assessment services for rotors, turbine disk bore/keyways, rim blade attachment dovetails, retaining rings, turbine main inlet sleeves and nozzle chambers, turbine and valve casings, blades, tenons, shrouds, and all other critical components. Our life assessment analytical services include EPRI®-licensed SAFER-PC© rotor analysis, EPRI LPRimLife© rotor disk rim dovetail analysis, EPRI RRingLife© generator retaining ring analysis, and ANSYS® finite-element stress analysis of shafts, turbine disks, and other components. In the case of turbine failures, our metallurgical testing laboratory also offers a full range of testing services for rotor, disk, and blade failure analyses.
As part of our turbine-generator condition assessments, Structural Integrity now offers full rotor bore machining services as well as plug removal, honing surface preparation, corrective machining, plug manufacturing, and plug re-assembly. In cases where rotor or disk material evaluations are required, non-destructive material sampling (via shallow scoop removal) can also be performed.
