Following a fire event, a horizontal recontracting drum required a thorough forensic assessment to determine if it remained safe for continued service. The engineering team performed an extensive NDT evaluation to check for material degradation across the vessel's shell, heads, and nozzles under API 510 standards.
What this video covers
- Performance of ultrasonic thickness testing at 17 condition monitoring locations using Echo-to-Echo mode.
- Analysis of corrosion rates to confirm minimal material loss of 0.5 MPY.
- Metallography and hardness testing to compare fire-affected steel against unaffected sections.
- Execution of a visual and coating survey for the shell, ladder, platform, and structural nozzles.
These rigorous inspection procedures provide the data necessary to verify the structural integrity of equipment following significant thermal damage.
