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.
An article describing this in some more detail can be found
on this site under:

a product descriptor can be found under

Please do not hesitate to contact me
if you require any more information.
