They use steel tanks for scuba...although most everyone has converted to
aluminum for
various reasons. The point here is that on the steel tanks, if there was rust
and/or pitting you
would have to have them rolled. This is where you fill it with gravel of a
specific type and
roll the tank on it's side so the gravel wears away the pits and rust leaving a
clean surface.
I believe the procedure is used with the scba tanks the firefighters use as
well.

I would recommend going at this rather carefully. Where I used to
work we had CO2 piped in around the plant in liquid form and they did
it in steel pipe. Whenever someone would make a new connection to the
valves in the system it was normal to blow out the crud from the
lines before making the connection. It turns out that in the liquid
form the CO2 is somewhat corrosive to the inside of the pipes and the
valves being the low points in the system would collect all kinds of
rust and other debris that was traveling in the system.
I guess what I am saying is open up one of the tanks and see what
condition the inside surface of it is. It might be rough and rusty
and not feasible to clean up and silver plate.
