Acoustic Emission non-destructive testing has the capability of monitoring of crack initiation and defect growth in high stress regions of components in real-time and without any shutdown. Failure analysis of a structure based on Fracture Mechanics methodology is a requirement of in-service inspection codes starting with the detecting of crack initiation, goes along the crack propagation and continues till final analysis of component failure. The activities of AEFA are summarized below:
- Determination of root cause of failures in plants during operation.
- Life assessment of cracked components by Fracture Mechanics.
- Assessment of sulphide-stress-cracking in sour environments.
- On-line crack growth monitoring of pressurized systems by multi-channel SPARTAN Acoustic Emission system.
