Turbine Rotor Examination and Evaluation System (TREES)

The SwRI turbine rotor examination/evaluation system (TREES) possesses unique examination capabilities and excellent flaw resolution achieved by computer-designed focusing lenses attached to ultrasonic transducers. Six lens configurations are employed to examine zones within the rotor with beam diameter sizes from 0.031 to 0.125 inch.

Nondestructive Evaluation

The SwRI turbine rotor examination/evaluation system (TREES) possesses unique examination capabilities and excellent flaw resolution achieved by computer-designed focusing lenses attached to ultrasonic transducers. Six lens configurations are employed to examine zones within the rotor with beam diameter sizes from 0.031 to 0.125 inch.

SwRI offers numerous nondestructive evaluation techniques for inspection of turbine rotors, disc steeples, and keyways, including periphery ultrasonic, dye penetrant, magnetic particle, and eddy current inspection services.

SwRI developed the turbine rotor examination/evaluation system (TREES), an automated rotor bore ultrasonic examination system for steam turbines that incorporates features such as focused search units and a volumetric cell structure to produce unique examination capabilities and excellent flaw resolution. Focused beam search units provide a reliable means of detecting and sizing flaws without using conventional signal amplitude techniques. An automated data acquisition and processing computer system processes the data. SwRI can custom assemble the TREES package and provide boresonic inspection services.

SwRI has extensive laboratory and field experience in developing and implementing internationally recognized inspection and evaluation procedures. Under a utility consortium program, an ultrasonic disc rim inspection system was developed that detects and sizes cracks in blade attachment areas without blade removal.

SwRI also conducts hardness measurements, replication, and microstructural assessments in the field using portable equipment.
