Dismantling a double hull stainless tank
 

I have this tank, which I craned today:

http://igor.chudov.com/tmp/Stainless...-Hull-Tank.jpg

(craning was done before wine consumption)

It is carbon steel on the outside, stainless inside, cork insulation
in the middle.

I need to separate stainless and carbon steel for scrap.

My question is how is the inside typically attached to the outside.

My best hope right now is that the inner hull was simply inserted into
the outer hull with very little welds between them. So, I hope, I can
just make a circular cut on one side where the mouth is, and pull out
the inner body from the outer.

Makes sense?

Cork is very compressible, so I would expect some type of supporting
structure on the bottom of the inside. I would guess it is welded feet
on the bottom of the inner tank.

Should still be a slip fit if you can cut and end completely off

Might be a spider or arms and not attached to either.
Might be disks or any form depending on the weight
of the center tank...
I'd take an end off and see what you find.

Id hang a quanity of C4 directly in the center, both vertically and
horzontally and then set it off. Will crush the cork and break the
welds

It woild even be cooler if the tank was filled with water.
Wouldnt need more than an oz or 2 of C4 depending on the size of the
tank.

Wouldn't a bit of det cord do the trick?

Pop the end and drag out the inner tank.

My brother used to be a scrapper.
He told me that the stainless steel milk tanks made by the "ZERO Corporation" were clearly labeled with their net scrap value....
Very similar construction.
SS liner, and insulation, with out shell.

Probably work fine, but Id use "trim stick" instead of primacord. Its
got a more focused energy path.

If you're talking about linear shaped charges , they are fun . Basically a
tube full of explosive with one side dented in to form a vee shape , and
they work better if you stand them off the surface to be cut a little . It's
been over 30 years since I worked at Thiokol , but a lot of that kind of
thing just sticks with you - like the time we "disassembled" a shed with an
8 lb block of C4 Poseidon propellant . There were a few pieces bigger than a
toothpick ...

Sounds like you were a blast to be around, Terry.

P.S: Were you a _real_ rocket scientist? ;)
