Abstract:
There
have been many recent changes in the technology surrounding materials in H2S
service. ISO 15156 was recently
released and will be replacing MR-0175.
Interest has also recently increased in improving the understanding
of the mechanism of corrosion in H2S service so that general corrosion and
pitting can be more accurately predicted.
The discussion will focus on some of these recent changes.
Robert Badrak will make a short presentation on
the new ISO 15156 document that will be replacing MR-0175.
Stephen
Smith will give a short presentation on corrosion mechanisms in H2S
containing environments.
