Short answer: Desalination and water treatment select metal by chloride and brine severity – duplex and super-duplex stainless for seawater duty, 316L for cleaner loops, titanium for the harshest erosion zones and lined carbon steel for tanks – to survive chloride, erosion and biofouling.
At a Glance
Seawater and Chloride Duty
Intake and brine lines meet high chloride, so Dúplex 2205 and super duplex lead, with the chloride science in our Corrosion Resistance Guide and marine context in our Marine and Offshore Guide.
Membranes, Pumps and Heat Exchangers
Membrane housings use 316L for clean weldability from our Placa de acero inoxidable 316 page, high-pressure pumps use duplex or Titanio for erosion, and chemical dosing ties to our Chemical Processing Guide; welding is in our Stainless Steel Welding Guide.
Tanks and Structures
Larger tanks balance cost with lined carbon steel or stainless, the coating choice in our Galvanized vs Stainless guide and surface prep in our Surface Treatment Guide; the structure follows our Stainless Steel Supplier ranges.
Specification and Care
Buyers set chloride rating, temperature and biofouling plan, then confirm with our Mill Test Certificate Guide and pack per our Export Packing Guide.

Preguntas frecuentes
Duplex 2205, with super duplex for the harshest brine and high-temperature zones.
For cleaner, lower-chloride loops yes; not for direct seawater at temperature.
In high-erosion pump and valve parts exposed to hot, sandy brine.
Only lined or coated, for tanks and low-risk structures.
Double the strength and far better chloride pitting resistance at similar cost per unit.
