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.

A Perfect Match: How to Select the Right Valve for Your Piping System

Valve is a control element in the pipeline system, it is used to regulate the flow of media or pressure, its functions include cutting off or connecting the medium, control flow to change the flow, change the direction of the media flow, to prevent the medium from flowing back, control pressure or discharge pressure. The ultimate goal of using valves is to ensure the normal operation of the pipeline, improve pipeline safety and efficiency. Therefore, it is very important to use suitable and correct valves.
