Looking for sst tubing supplier

[davehaigh]

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

Let me clarify what my real issue is. I have been unable to find elbows and tee's in a 12" OD.

Straight sections are available in rough form. But I would rather have a vacuum or sanitary quality interior finish on it.

The thickness isn't a hard number it can be thicker. Can't be any thinner.

David Haigh,



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.

Thanks for all the suggestions. A lot of vendors I didn't know about, which is helpful.

I did find a vendor that has large diameter SST pipe elbows and other fittings.

Not really the most appropriate forum for asking "Where can I buy" the questions, surely?
