Obsolete allowable stress values

[AmDg2]

Has anyone ever heard of a publication listing past allowable stress valves from previous Codes?

As an Engineer working in an older plant, I spend some time looking at original Codes of construction (which we have in their original context, back to the 1930's). It would be nice to have allowable stress values, with notes, in one location.

Thank you

If you are doing a major repair on a pressure vessel, you have no choice but use the code used at the time of manufacturing, therefore you may get involved with obsolete stress values.

If you are performing weld repairs to a pressure vessel, they can fall under the National Board Inspection Code (NBIC). This is a repair code that does allow for later editions of the code of construction to be used. The "original" code of construction pertains to the code the vessel was designed and fabricated NOT the original year of construction.
