Analysis of Seawater Butterfly Valve Salt Spray Corrosion Resistance Technology
In seawater transportation, marine engineering, and coastal industrial systems, seawater butterfly valves are exposed to high salinity, high humidity, and oxygen-rich environments for extended periods, making them highly susceptible to electrochemical corrosion and salt spray erosion. Chloride ions in salt spray have extremely strong penetrating power, damaging the passivation film on metal surfaces and causing pitting corrosion, crevice corrosion, and even stress corrosion cracking. Therefore, improving the salt spray corrosion resistance of seawater butterfly valves is crucial for ensuring the safe and stable operation of the system.
