About this document
Caustic Gouging in Boiler Tubes by Praveen Patil is a document available to read on EtoBox.
1. Dissolved oxygen in boiler water can cause severe pitting corrosion, especially at the water level in the steam drum. Variations from the optimal pH range of 10.5-11.5 can also cause general corrosion through acidic or caustic attack. 2. Acidic attack below a pH of 8.5 can cause waterside thinning and etching, while caustic attack above a pH of 12.9 can cause irregular gouging as high concentrations of sodium hydroxide form. 3. Steamside tracking in lower temperature areas is a form of corrosive attac
