Seawater is used at many facilities, including desalination plants and power plants that use large amounts of cooling water. However, stainless steel and other materials corrode in seawater. Ebara has extensive knowledge and experience in dealing with the causes of corrosion, e.g., sea-area-dependant salt concentrations and temperatures, material types, difference of potential between materials,water flow, and velocity differences. Thus, we can ensure the stable pumping of seawater through the proper selection of materials, cathodic corrosion protection, BEM-based corrosion prediction analysis, the development of duplex stainless steel fabricated pumps, etc.
