If it's a used storage, probably has rust inside, so the thickness is less of 8 mm. Meanwhile, you can open it and see its condition. The biggest problem is that if it explode, it's like a bomb. The storage in photo is also damaged, so I would not use that.

yes but why you think this bad idea if welders cut front do doors and everything this can is big and good they holded water. and thickness 8mm of wall.

for me, it'a a bad idea use the storage in photo.  You can ask to a storage factory a new factory without a bottom, then do the door and settle and check the welds. Rimember, an autoclave is a big bomb...if you have a 1 m diameter door, with 5 bar of internal pressure, you have many tons of thrust....

what you guys think is it wortjk my friend sell this it was used for water and etc to store. so i thought i could buy and to ask factory to do doors and to ask other guy who genious with electricity to do heating inside and computer that rise and cool down inside on this canister big? what you think is it great option for autoclave? as normally i asked how much used autoclave so in uk they charged 180.000 euro. i do lotttttttt cheaper. I TRY TO DO INSIDE LIKE ON HOTO NUMBER 2. YOU THINK GOOD IDEA TO BUY SO BIG STORAGE LIKE FROM PHOTO 1? IT IS 3 METRES LONG 1.5 METRE HIGH AND 1.2 METRE WIDTH
