Condensate Induced Hammer Pipe Damage?

Condensate Induced Hammer Pipe Damage?

(OP)
Found this in a 50# condensate pipe run.  Any ideas on the damage mechanism? It's carbon steel pipe.

RE: Condensate Induced Hammer Pipe Damage?

I assume it is pitting corrosin in the photo? if so CO2 is likely the corrodent. You will need to vent the non-condensibles or provide additional amine inhibitors.

Or is it blistering?  What does it look like lightly cleaned?

Rounded pits with steep walls, I woulg agree looks like CO2 pitting, have water in your condensate accumulating/condensing here.

CO2 corrosion (carbolic acid is the classic mechanism in condensate piping systems.

But your picture looks more like an O2 corrosion mechanism
