Water treatment relies on stainless steel's resistance to brackish conditions:
Saltwater Resistance:
2507 super duplex channels (PREN ≥40) resist 70,000ppm salinity, lasting 20 years in RO systems-5x longer than 316L. Saudi Arabia's Ras Al-Khair plant uses these.
Pressure Handling:
Channels with 12mm thickness withstand 8MPa feed pressure, maintaining membrane alignment within 0.5mm. Israel's Sorek desalination plant employs these.
Cleanability:
Smooth-channel surfaces reduce biofouling by 70%, extending membrane life by 2 years. Australia's Perth Desalination Plant uses these.
Global Preferences:
Middle Eastern plants use ASTM A790 S32750 channels for extreme salinity, while Mediterranean facilities prefer EN 10088-3 X2CrNiMoN25-7-4 channels for balanced cost and performance.
