I need some heavy wall tubing sst 316, .083 thick with a 12" OD.
Especially need Elbows and Tee's. I'm not finding any elbows or tee's or any other similar components from traditional vacuum parts vendors. Looked at sanitary tubing vendors, they don't go up to 12". I'm thinking oil refineries or other chemical processing plants must use something like this but can't find anything. I hate to have to fabricate these parts. Traditional spiral lockseam ducting will not work in this application.
I need to weld on ASA flanges. MDC Part # 160019, asa-19B Nor-Cal Part #'s asa-16-1200r, & asa-16-1200n

Trying to find anything that large in stainless steel piping is pretty tough. When I was working for Cummins Diesel we had a similar problem because we needed corrosion resistant tubing for a very high volume of air.
What we were looking into was either forming our shapes (elbows, fittings, etc) or investing in some pretty expensive molds. Probably not really good news. But that is what I was able to find.
