Marine Boiler-safe working pressure after finding pitting marks

[renjith_p]

On finding pitting on a water tube marine boiler, after inspection, how do i check for its safe operating pressure? Would it be safe to fire it and bring it up to its design pressure as stated by the maker?

I wouldn't operate this boiler without obtaining a thorough inspection of the unit from a reputable boiler inspection authority.
