Non destructive
evaluation of metal tanks and pressure vessels is crucial to the
safety and operations of a plant. Most non destructive inspection
techniques require costly shut-downs and are time consuming
processes. Therefore, only certain areas of the structure are
inspected, usually those of higher defect probability, such as welds,
nozzles etc. Acoustic Emission (AE) is a non destructive evaluation
technique, offering in-service, global inspection of structures. The
vast majority of above ground metal tanks and vessels are assessed
according to ASME section V and MONPAC, Acoustic Emission evaluation
procedures. The present work outlines the use of AE for tank and
vessel testing and provides some representative examples.
