Comments
Hydrogen damage is an under-deposit corrosion mechanism. Damage occurs in high heat areas (e.g. above burners). Often associated with one or more low pH excursions in the boiler and/or long-term contamination (condenser tube leak). High probability that other tubes are similarly affected. All affected tubes must be replaced.
