I always thought it was not a good idea to add anything to the boiler.
I even heard flushing out the boiler and adding new water is bad cause
it adds more oxygen, which means more corrosion.

I used a corrosion inhibitor in my hot water system, but can't speak
for residential steam boilers.
Since it's pretty new, you should check the manual.
You should replace that pipe ASAP.
If it breaks with somebody nearby it could kill them.
Guy I worked with got killed opening an overhead steam trap on a
depressurized line.
Just the water running out scalded him to death.
