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.

SITEX CPSERIES

Teledyne ICM’s CPSERIES has been designed with a view to revolutionizing the handling and perfor
...
mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
