Pitting Corrosion of Marine Steam Boilers - The Case Study

Abstract

On the grounds of the inspections performed and the results of metallographic tests, the causes of pitting corrosion of combined, auxiliary oil-fired boiler were described in this paper. The boiler generated saturated steam. The methodology and the scope of the carried out tests are indicated, photographs are included as well as the description of damages and documentation regarding the metallographic tests. Conclusions which arose from the abovementioned tests and operational recommendations for engine crew were developed.
