tofd applications for hot hydrogen attack on carbon steel

I have heard of a TOFD application for measurement of hydrogen damage prior to the micro-cracking stages, I have a 3" carbon steel vessel that needs assessment work done, there are no available samples that have not been exposed for velocity ratio. Vessel is 18 years in service.

Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection

This set of two blocks has been specially designed for situations where ultrasonic examination tak
...
es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.
