Duplex SS 2205 for pressure vessels
Duplex SS 2205 for pressure vessels
(OP)
Hy everybody, I'm working on the design of a heat exchanger and the client asked tubes of Duplex Stainless Steel 2205.
I couldn't find that material on ASME Section II - D, I could only find Duplex SS 2750.
Could the SS 2205 tubes be used for a pressure vessel calculated with ASME or should some other requs be fulfilled.
Please if anyone could give me some requirements or suggestions they'll be welcomed.
Thanks in advance!
Peter

RE: Duplex SS 2205 for pressure vessels
depends on the SA# probably SA789 or SA790 its alot easy to look up by P# 10H. Hope this helps.
RE: Duplex SS 2205 for pressure vessels
What do you mean with look up by P#?
RE: Duplex SS 2205 for pressure vessels
Please check Code Case 2488-2 regarding the use of these materials. It provedes the necessary information for your design.
RE: Duplex SS 2205 for pressure vessels
Maybe the Code Case fegenbush referred to allows it. Can you detail where in II-D 2205 can be found ASMEQC?
RE: Duplex SS 2205 for pressure vessels
Guys I opened my mouth to soon. LOL
The tubes that we use are SA789-2205 (UNS #S31803) i do apologize for the confusion. I looked all through SEC. II part D and i did not find any tube or pipe the is UNS # S32205. Or any material that has that UNS #
Peterway do you have the tube on hand if so what does the MTR say they are.
I have a MTR from our last job and it is duel certified.
