The OPD fitting is simply a new valve that is screwed into the tank, replacing the original valve. There is no welding involved in installing a new OPD valve. The certification dates are stamped (or engraved) onto the collar of the tank--there is no magic to this. While I am not advocating this, anyone could put a new date on the collar of the tank and it wouldn't be questioned.
Again, if you have a carbon steel tank and it is out of date, throw it away and get a new tank--they are not worth messing with. Also, any person who might fill your steel tank could refuse to fill it on the basis of rust, regardless of the last certification date.
