New Phased Array Application for Inspection of Contact Point Corrosion on Piping

This presentation is directed at NDT practitioners, responsible Level IIIs, and asset owners faced with the challenges posed by aging infrastructure and inspection of contact point corrosion.

Visit Website

Inspection of contact point corrosion has been a longstanding challenge in NDT. Pipe resting on supports often exhibits corrosion at the touch point, which due to limited access cannot be inspected by traditional direct methods. Numerous techniques have been developed and deployed over the past 20 years to address this challenge including piezoelectric and EMAT ultrasonic methods. Recent research into the application of phased array ultrasonic testing (PAUT), developed as the PA-CATTM technique, provides a robust, effective solution which utilizes existing PAUT instruments, probes, and scanners.

This presentation is directed at NDT practitioners, responsible Level IIIs, and asset owners faced with the challenges posed by aging infrastructure and inspection of contact point corrosion.

By the end of this webinar you should:

  • Understand the basic approaches for contact point corrosion inspection
  • Identify the advantages and challenges of different methods
  • See how PAUT can be used for improved inspection results
