Inspection of Process pipes into a guard pipe

Dear Sirs;

We have designed a piping system that include a guard pipe containing 4 process pipes (all pipes made of SS 316L) as you may see in the attached file.

Final client has asked if it would be possible to perform a corrosion /loss of thickness inspection of process pipes in some specific areas obtained from the stress analysis. Does anybody know any technique that allow this kind of inspection without cutting guard pipe?

In the attached file you may find dimensions and configuration of pipes

Thanks in advanced

Can you do RT thickness measurement at 2 directions (90 degree)? You can use outside diameters of the process pipes for reference comparator to determine the wall thicknesses.
Another option would be use IRIS for tube inspection.

...
oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
