[labnetwork] Stainless Steel Tubing

[David Wolff]

For what gas ?  The denser the gas, the more the pressure drop in smaller tubing.  For hydrogen, the ¼" is fine.

I have gotten recommendations that I should use 3/8" SS tubing EP 316L, but the availability of that is out into May or June of 2023.  ¼" is better.

But can I use ¼" with a process that runs <1slm?  The fittings to most of the tools is ¼" VCR or swagelok.  But I have a 90ft run in one case.  Any guidance is appreciated.
