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

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....

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.

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.

photo number 2 is an real factory autoclave on first im think to buy that tank. it cost me with delivery 500 pounds.

Hi there...

Using an old "pressure vessel" or Tank as a homemade "autoclave" may seem like a good idea, but it all depends on the pressure levels you are looking for  and the temperatures.


Normally tanks of that type are made for the sort of pressure levels found in water mains or compressed air tanks, in effect a maximum of 7 - 10 Bar ..

Someone with the right skills could cut off one domed end and weld on sufficiently thick flanges to allow the tank to be opened, but doing the specialized revolving door "Bayonet" fitting setup seen on the commercial autoclave, takes a lot of knowhow and machining.. and money ...

only other way is to use a large number of bolts and wing-nuts or similar on straight flanges, welded on to the end of the tank and use one curved end as the lid/door, also with a welded on flange.  It will be very slow to open and close, and a right pain to keep it pressure tight..  (Large rubber seals needed around the flanges)

Then you need to think of the heating systems inside a pressurized tank... heating up the air will increase pressure ... quite a lot actually ...

There is a reason why commercial autoclaves are so expensive.....

The written word is the only truly efficient vehicle for transmitting a complex concept from mind to mind...

103% of all people do not understand statistics...

Do not adjust our mind, theres a fault in reality :-)

yes i agree this hold 8 bars. and in good condition. i talked to guy to cut and to do doors to other genious i talked he do everything inside and outside and third guy do sensors and computer that can regulate air preassure and heating with digital monitor and sensors all over!

Hi Tom

so guys maybe then i order already builded tank? how much preassure and temperature it has to hold inside?
