Material Selection for Industrial Desalination Piping and Valve Networks
Why Super Duplex Stainless Steel and Special Bronzes are required to resist pitting and crevice corrosion in seawater desalination intake lines.
1. Seawater Corrosion Challenges
Seawater desalination plants operate in aggressive, high-chloride environments. Standard stainless steels like 316L rapidly fail due to pitting and crevice corrosion under hot seawater conditions.
Super Duplex Stainless Steel (25% Chromium, PREN > 40) is the preferred material for high-pressure reverse osmosis piping. It offers high mechanical strength, enabling thinner pipe walls, which offsets high material costs.
