How to Combat the Hidden Killer of Valve Materials—Chloride Ions

Chloride ions, as small yet highly reactive anions, can easily penetrate the passivation film on metal surfaces, triggering pitting and crevice corrosion. They are known as the “deadly toxin” for valve materials.Selecting valve materials for chloride-ion corrosion environments is a technical task requiring comprehensive consideration of multiple factors. The fundamental prioritization principle for material selection is: corrosion resistance > temperature > pressure > cost. Proper material selection not only extends equipment lifespan and reduces maintenance costs but is also a critical element in ensuring production safety.
