for the containment vessel shell, which is listed with a 6720psi
bursting pressure; and

0.6" diameter? Small one then. So it is just a piece of small pipe.
Forget ASME then.

Anyway, the pressure rating is not at 500C, but I doubt it will be
a problem except perhaps at connections.. You propably do ok with
thick-wall tubing and ferrule-connectors.

The C-Ring seal suggestion is /much/ appreciated and I'm planning to see
what other metals are available (since Iconel is primarily a nickel
alloy and this particular reactor considers Ni to be food). :-)

Guess what there is about 14% in 316..

Yuppers. The 14% might be tolerable, but the plan is to copper plate all
interior surfaces of the containment vessel/reaction chamber to avoid
problems there - but I'm not very confident that this approach would
work well for seals.

According to Wikipedia, Iconel varies from 50% to 72% nickel - so I've
been looking at C-ring and omega-ring seals in other metals/alloys.

The seals are something I didn't even know to look for before your post,
so you've (already) been a real help!

Thank you.
