Combatting Localized Galvanic Corrosion at Bolted Connections in Gravity Sludge Thickeners and Clarifiers in Wastewater Treatment Plants

This paper will describe this commonplace corrosion problem associated with protective coating damage at dissimilar metal bolted connections and present a typical case history. The paper will go on to explain why slotted bolt holes are more susceptible to more aggressive corrosion damage than round bolt holes. In addition, the paper will present successful measures that can be taken to prevent this prevalent problem.

This paper will describe this commonplace corrosion problem associated with protective coating damage at dissimilar metal bolted connections and present a typical case history. The paper will go on to explain why slotted bolt holes are more susceptible to more aggressive corrosion damage than round bolt holes. In addition, the paper will present successful measures that can be taken to prevent this prevalent problem. Those measures include proper coating system selection, the use of non-metallic washers with stainless steel washers, reducing the number of bolted connections, and application of a flexible polysulfide sealant to seal bolted connections following proper coating application.
