For example, free caustic in the boiler water can concentrate along a waterline in a horizontal tube by repeated splashing and evaporation, resulting in parallel longitudinal gouges. If the upper portion of the tube is exposed to a heat flux, boiling action can also contribute to concentration of aggressive compounds and result in localized corrosion damage.
