Webinar: Detect and Assess High Temperature Hydrogen Attack (HTHA)

In the Oil and Gas industry, High Temperature Hydrogen Attack (HTHA) can occur in steels operating at high temperature, usually above 205°C (400°F). Early stages of HTHA are very difficult to detect because of the small size of the methane voids, much smaller than the commonly used ultrasonic wavelengths. The degradation can build up over time, ultimately resulting in unexpected plant downtime, reduction in productivity, employee safety hazards and even catastrophic damage to critical assets. Due to the inspection challenges presented by HTHA damage, a combination of advanced ultrasonic examination techniques, with carefully selected instruments and probes, is recommended in order to achieve an efficient and reliable inspection. Also, operators that have been specifically trained using these techniques will gain a significant inspection advantage. View this webinar presented by Guy Maes, Sales Engineer Director UT for Zetec. The webinar demonstrates how these advanced ultrasonic techniques, implemented on the TOPAZ64 portable phased array UT system, are deployed for HTHA inspections. The session will include the following topics: • Introduction on HTHA, the specific inspection challenges related to this damage mechanism, and the recommended inspection strategy • Principles and application of various advanced ultrasonic techniques • Discussion of UT examination results on samples with confirmed HTHA damage • Considerations on probe design optimization If you are involved in NDT inspections in the Oil & Gas industry, this webinar will provide new insights and clarification about the benefits of these advanced ultrasonic techniques.
