WebJun 3, 2001 · Galvanized steel performs best in solutions with a pH in the range of 5.5 to 12. pHs between 3 and 5.5 (acidic) or 12 and 13.5 (basic) are corrosive to galvanized steel, but the galvanized coating will still give corrosion protection to bare steel, although the protection will only last for a few years. If a longer service life is desired, then ... WebMay 10, 2024 · Decades ago, before cooling towers were allowed to operate at higher internal pH levels, internal white rust wasn’t really a problem. However, after consumers began to demand sulfuric acid’s removal from water treatment systems to maintain a neutral pH (7.0), systems were optimized for the more basic (around 9.0) internal water solutions. … Rust is a general name for a complex of oxides and hydroxides of iron, which occur when iron or some alloys that contain iron are exposed to oxygen and moisture for a long period of time. Over time, the oxygen combines with the metal forming new compounds collectively called rust.
