Lessons Learned – Penetrant Evaluation of Metallic Tanks and Composite Overwrapped Pressure Vessel Liners
Year: 2009
Abstract: Abstract:
As the desired crack detection size is decreased and approaches the physical limitations of liquid penetrant inspection techniques, the approach of performing a probability of detection (POD) validation test at a single aspect ratio, and then extending the results to other aspect ratios based on equivalent area predictions may not be valid. POD testing for penetrant inspection of metallic pressure vessels and COPV liners should be performed at the bounds of the required range of crack aspect ratios.
