Well, we didn't find any tubercules or carbuncles or anything. Just looks like someone took a bevelled drill bit and machined clean, neat little holes from inside the 3/4" i.d. tube. Like boilerbores. Or boiler weevils. The holes are 5/16" diameter inside the tube (waterside), and tiny pinholes on the outside.
The boiler supplies cooking process steam to jacketed stainless steel kettles. Most of the condensate is returned. I can't imagine any other chemicals getting into the system unless it's from the water treatment. I'm thinking it's O2 corrosion.
Thanks.
