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:

• Tank bottom Testing without removal of product.
  
• Inspection of Insulated Piping & Vessels
  
• Real time monitoring during cool-down & start-ups
  
• Real Time Monitoring Saves Money and Improves Safety
  
• Make informed decisions on when and how to conduct further condition assessment programs.
  
• Prioritize capital expenditures by enacting a selective repair and replacement program that is based on current distress levels.
  
• Manage the inherent risks of operating pressurized concrete pipe. A long-term monitoring program enables an operator to establish the rate of infrastructure deterioration.
  
• Accurately value pipeline assets on there current condition, thereby complying with legislative requirements
