Assuming the tank is built to take significantly more than 2 atm of
positive pressure, could you possibly implode it even if it had a
perfect vacuum inside?

I dunno for sure, but probably not.

there was a thread in rcm a couple of years back about rail and truck
gas transport tanks collapsing, after being serviced or repaired. the
tanks were at closed up at 1 atm, (IIRC). --Loren
