Caustic corrosion in boilers - Lenntech

Concentration of caustic (NaOH) can occur as a result of steam blanketing (which allow salts to concentrate on boiler metal surface) or by localized boiling beneath porous deposits on tube surface. Caustic corrosion occurs when caustic is concentrated and dissolves the protective magnetite (Fe 3 O 4 ) layer, causing a loss of base metal and eventual failure.
