Shipmates,
Please let me repeat what the archives are replete with. Propane
tanks are built to withstand intenal pressures. They are not built to
withstand external pressures. So their published (internal) pressure
ratings have absolutely nothing to do with their external pressure
ratings.
It would probably be a good educational exercise for one of the engineers
in the group to run the numbers on the internal and external pressure limits
of a standard propane tank, to show how much lower the external ratings are
than the internal ratings. Will anyone volunteer for the task?
