Thanks for you help guys. Totally unrelated but the P number for our zirc is P61, not 66. Sorry about that.
I believe for now, thats all we have DVWE. I have submitted an ASME Sec IX interpretation request. Now for the 6-12 month wait.
Dekdee, in response to your first statement. That's...
Again, your assuming the term Process is only related to the method of how its applied. Where does section 9 define process as only a method and not a process with related variables. The interpretation clearly states "for which welding variables have been established. I can copy and paste...
Gents,
Supporting interpretation first.
Question : “What is the definition of the word “process” as it is used in QW-322?”
ASME Reply : “The word “process” refers to those welding processes for which welding [highlight #FCE94F]variables[/highlight] have been established in...
Looking for these as well.

Little bit. I see where it indicates increased corrosion rates at elevated temperatures. Temperatures aren't specific. Acids, water, and salts make for accelerated corrosion as well. Contaminants such as water, sulfides, acids and various organic compounds can increase corrosion significantly...
I have exhausted my personal resources. Looking for some guidance. We have a two SB-96 C65500 vessels that typically operate at 118 to 133°C. The previous vessels lasted +30 years and I'm not positive on their operating temperatures then. Current vessels have lasted 10 years and are on the...
