Advanced / Specialist Non-Destructive Testing

Acoustic Emission Testing  (AET)

The Acoustic Emission Testing NDT technique allows for real-Time 100% volumetric monitoring for structurally significant defects, yet is sensitive enough to detect inclusions, cracking, embrittlement, corrosion, stress corrosion cracking and other propagating defects. It requires stimulating defect sites by raising the pressure to 110 – 115% of the normal operating pressure. For static tests, it requires isolation and settling time for corrosion monitoring.

Main benefits of AET:
