Corrosive Chronicles (Green Theater) / Booth 2011

Corrosive Chronicles

Contamination of Stainless Steels

3:00 p.m. to 4:30 p.m.

There are many potential sources and types of contamination of stainless steel (SS) equipment and piping components.  And when the problem does happen, schedules get held up, valuable resources are brought to bear, money is spent, and company reputations suffer.

Most often, it is iron contamination that is seen.  The heat tint from welding may be considered another.  In industrial strength hydrogen peroxide services, even tungsten contamination from the arc strike of a gas tungsten arc weld (GTAW) electrode can spell disaster. So, what is it about not-so-stainless, stainless steel equipment and piping that causes its outright rejection?  What are the real corrosion issues?  What is the technical basis for rejection?  And what are the options to treat it?

Attendees are invited to bring both their views and practical experiences to this open forum.  We can discuss how to identify the types of contamination, how to assess their risk, how to remove them, and how to specify against them.  This will be a great opportunity to network with those like yourself who are likely to contend with this reoccurring problem.
