Abstract
Localized corrosion occurred in a 27-mile (43-km) phosphate slurry pip eline in mountainous terrain of southeast Idaho. Sulfate-reducing bact eria, Desulfovibrio sp., found within pits appeared to be responsible for the localized attack. However, dissolved oxygen in the slurry caus ed the primary corrosion in the pipeline. Preventive maintenance invol ved corrosion monitoring and periodic replacement of upstream pipeline sections where corrosion damage exceeded design specifications.
