I agree with your sentiments in general -- however, these are not ICC/DOT
tanks which need to be recertified within 12 years after manufacture, but
ASME tanks which have no recertification requirement.  They are massively
overbuilt for the amount of pressure they contain (max 250 psi (relief
valve opens) , ordinarily considerably less -- call it a tenth of a welding
cylinder or SCUBA tank).
