metengr,
The service environment would be about 1100 F @ 50 psi and the process is typical thermal oxidation with NOx, CO, CO2, H2O. Increased oxidation is amongst my main concern in this reactor.
Thanks guys, the info you've provided has helped me to make a good decision. I really appreciate it.
thanks davefitz,
I'm not very familiar with the ASME code. From your reply I take that I can't go for 1.25 Cr-mo for this reactor. Perhaps I should just picked SS304 for this duty
I'd like to specify a Cr-Mo reactor (8 ft diameter) which can potentially see 1150 F @ 50 psig. SO far various info I've found suggests we cannot go beyond 1050 F. Our internal pipe spec however says 2.25Cr-Mo is good up to 1200 F. Can gurus out there give me some advice?
