Hydrogen embritllement study using UT

I am interested in knowing the techniques used in identfying the presence of Hydrogen embrittlement in hydrocracking vessels in oil refineries ( thickness about 100 mm. )

Re: Hydrogen embritllement study using UT
The easiest method for you may be to utilize a manual Rockwell hardness tester. Compared to a known calibrator, you may establish RC hardness guidelines.

Re: Hydrogen embritllement study using UT
AEA Sonomatic BV has been working in this area for over
a decade now and has build up a vast reference in this
application. Procedures were validated with clients and
Authorised Inspection bodies such as Stoomwezen (1992)
and TueV Nord (1999). Procedures are based upon research
of established research institutes and our own research
and practical experiences.

Product Spotlight


Next generation for Phased Array UT is here now with FMC/TFM! Have higher resolution imaging, impr
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
