Heat exchanger: non-metal tube to tubesheet assembly

Heat exchanger: non-metal tube to tubesheet assembly

(OP)
Hello,

I'm working with some ceramic tubes of small diameter (~0.08"OD) that I need to implement in a heat exchanger. I'm looking for documentation or design advise on how I could connect/seal them to a tubesheet as I don't have lot of experience in this. Pressure expected are around 200psi.

Thanks

And what is the temperature?

Temperature would be a max of 1600K for 3sec. The thing can bleed and not be perfectly sealed, it's not a big deal. I just need to get a "best effort" in the first place (and by that I mean as soon as possible).

RE: Heat exchanger: non-metal tube to tubesheet assembly

If they don't have to seal, ceramic cement- refractory mortar- muffler cement- glue them into a close tolerance hole.

Otherwise, good luck.

Yep that's approximately what I'm doing with mitigate result.

Thanks though

RE: Heat exchanger: non-metal tube to tubesheet assembly

One end sealed with cement, the other end sealed with metal foil rings.
I have seen them folded to make a "V" and then rolled into a ring.
They try to spring open and sort of block the gap.

Hey Ed,would you mind when you have a few minutes do a basic (like paint) drawing to show the general idea? Not sure I get exactly what you mean.
