Deformed pot

[cruizer8]

So I have been brewing for about 3 years now and its been in the same 8 gallon aluminum pot. About a year ago I decided to start BIAB and its worked great for 8 or so brews. However, today while I am brewing another one, I hear a pop and notice the bottom of the pot now caves upward and the base is now a hexagon instead of round. Looks like I will be getting a new kettle!

Anyone else have this happen to them?

And this is what the damage looks like.

Wow - how did the hell that happen? Did you dry heat it by any chance?

That's a piece of art!
It's a heptagon actually. Did you do that funny dance around the kettle again, teasing the brew gods?

But seriously, I've never seen anything like that, or even deemed possible from just heating.

Did you have your lid on? Any rapid cooling? Were you running a pump or using one of your valves?

It almost looks like some sort of vacuum was formed and your pot imploded.

Whoa!

Interesting deformation for sure.

 

[schematix]

looks like a crushed tank... lol. i've seen this happen in 50000lb tanks before but not like this. what were you doing?

Perhaps a Troll stepped on it

This is the only explanation.

That's crazy.

And... that's all I have to add.

Does this look familiar?

Looks like they cooled with the lid on and created a vacuum situation. It doesn't take much pressure difference to do this.

Hulk SMASH!

I kinda want to buy a cheap throwaway (<$10) pot and try to recreate this situation...

It would be pretty cool. Of course you might die too.

That pot must have had a hell of a good lid to seal that well.

I'm a little surprised this hasn't erupted into a SS vs. AL thread.

Perhaps a job for the Mythbusters

I've seen the bottom of pots bend upward if you cool them off with cold water while they are still hot, but nothing to this extreme.

I'm a little surprised this hasn't erupted into a SS vs. AL thread.

And this is why I want one of the thick 0.25" Al pots.

Think about it this way, you can whirlpool and aspirate from the center and get crystal clear beer.

I had about 5 gallons in it and had my grain in there for about 15 min with the water at 150° with the lid off. It was about 40° outside, but I have brewed with the same pot when it was below freezing. It looks pretty cool but I am surprised it didn't cause a geyser or something.

I guess I did add about half a gallon of room temp water but wouldn't think that would be enough to cause that.

Or you could try this...

Excitement is around 2:21 mark.
