Being American Standard I think it's for coating the unthreaded,tapered nipples between boiler sections

Correct, sagefinds...my 46 year career was in the jobbing foundry business.  Made various sizes of radiator and boiler section nipples by the thousands for U.S. Boiler, Dunkirk (NY) Radiator, etc.  Very lucrative Class 30 grey iron jobs to include machining them.  Great value added.

 

Next time you see a few radiator sections joined together there are pressed fit nipples joining them.  (yes, folks grey iron is brittle yet once machined they press fit simply due to the tapered machining.)
