Collapsing 55 gal drums

[philkasza]

We have filled several different 55 gal drums this year and a couple drums changed shape after cooling. We canned them at 190-195 degrees, it that too hot or what would cause them to do that? Or are the drums just not strong enough?

Thanks

What kind of drums are they? Did you fill them all in one session or were they filled a little at a time so it took a few days to fill them?

Sounds like they were cheap drums,like the ones nys ***.bought a few yrs back ,they did the same thing,not heavy enough gage stainless steel,you need to put it in a barrel 185 and above
