At that point you're not dealing with a "flimsy structure out of thin steel foil" that you can inflate to hundreds of psi. You described what's basically a submarine, multiple high and low pressure hulls able to withstand hundreds of psi of pressure.
Just for some reference, 1000psi is the kind of pressure you get ~700m depth (2300ft), double what a submarine would regularly withstand. Pressure in your average propane gas tank probably peaks around 200psi in high temperature. That steel isn't flimsy, it tends to get bulky and heavy even with creative ribbing and reinforcement.
It has to make a lot of sense practically and economically to consider such an option. So it ends up being used in places where weight or cost matter less.
- londons_explore 2y agoA CO2 fire extinguisher is about 1000 psi.
- buran77 2y agoA 1000psi fire extinguisher uses ~5mm thick steel even for that relatively small diameter cylinder. A typical extinguisher is ~200ish psi with a wall probably ~1mm thick. This highlights that high pressure and "thin steel foil" do not go well together and don't scale in your favor. Pressure makes any failure considerably more dangerous.
