Thanks. Not gunna use em…i drove 3 hrs to humboldt and paid 1k for ten of these fucks from hanz707…he didnt say anything about the dents…kind of scummy…i didnt have to buy them, but i didnt see an issue at the time. Forgot about running sub zero and how that would fuck it up. Next time some fucker is selling columns ill ask about dents lolz. Oh well… got a deal on some other shit that wasnt fucked up. Live and learn…8==D~~:heart:

I have some dented glass spd boiling flasks if your interested.
And if you want to summon someone, use an @ before their screen name. You called for @cyclopath for help, I’m sure we were nicer that he would be. Dented cls… oh boy.

Could be damaged, not visible to the naked eye, add really cold solvent, +/- pressure, heat,
A bit risky maybe
Can’t running with nitrogen also bump up the risk of bursting stainless spools if the stainless spool is already structurally damaged?

Brittle failure is not the singular possible failure modes. You have metal with stress concentration points i.e. visible indentations. First thing you need to get straight regardless of your cursory google searching is that no material gets stronger at reduced temperatures, austenitic or not. When things get colder, they get harder - when things get harder their strength (ability to withstand applied loads) reduces. Failures of all sorts notoriously propagate at stress concentration points. Embrittlement aside, you are STILL subject to fatigue failure or rupturing from cyclic loading and unloading of forces where cracks and imperfections form/spread from your stress concentrations.
While you MAY not ever have an incident running these columns, your attitude towards process safety is deeply concerning. So you got these columns for damn near free and for that minor savings you are willing to eschew practices which promote the well being of yourself and others (not to mention the reputation/growing integrity of our industry) over a tiny little bit of money saved. The essence of process safety and hazard analysis/avoidance is to be vigilant and exert zero tolerance for situations with significant or reasonable potential for failure, and to absolutely never prioritize production/cheaper solutions at any potential cost to operators or the community. Beyond this being a foolish endeavor, its also a greedy and unethical one. I would reconsider using damaged pressure equipment at this pre-operation stage, rather than risk damage to yourself, employees, emergency responders, the environment/community, and our industry as a whole via negligence. You can still pat yourself on the back for making a good decision and prioritizing safety. I get that folks have a hard time admitting that they are doing something wrong, but its easier to admit that you could do something better. And its okay to make mistakes from a momentary lapse of judgement or distraction/forgetfulness, but it is decidedly NOT forgiveable to have reckless indifference towards the safety of others.

Not that ive ever seen, but i also avoid that place like the plaque unless absolutely necessary. There pretty much done up here anyway.
Late to the party…
didn’t get the invite 
Not a lot left to say…thanks to @eyeworm, @TheGratefulPhil & @Concentrated_humbold.
Would I use those for hydrocarbon extraction? Nope!
Would I try and figure out some other way to use them? Quite probably…
One that stayed fairly close to ambient temps, and below 15psi. The only thing that comes to mind was stolen from @chempistry upthread…and if one could afford to pack those things with C18, then chances are one could afford more appropriate chromatography columns.
If we were moving milk around in a dairy, then the risks involved would seem pretty minimal, but given the intended use (thermal cycling, under pressure, while full of flammable gas), the risk doesn’t seem worth the cost savings.
@Rainbowp3nis, glad you’ve decided not to put the cannabis in these particular tubes.
Perhaps they could be used for stripping terpenes under vacuum?!?
bonus points if you get the “heat” by painting them black and racking them up (horizontally!) in the sunshine…

I’d love some beat up stainless to practice welding on.

Well he has them for 100 a pop
I almost have the $180 it’ll cost me to to outfit my Hobart mig with 308 wire and helium shield gas. To fix things like this.
I’ll experiment with scrap first. I’ve welded carbon steel air tanks so I think I can get it done. But I have to do some studying on how to prep for stainless and post treatment.
I only say this because it would be elevated temps and low pressure…
You could use them as shells for shell and tube heat exchangers/FFE solvent recovery. Not ideal, but certainly a better use than scrap.
