Public agencies struggle with the cost of desalination and water treatment projects, and expect expensive stainless steel materials to last as long as the bond payment period for their capital improvement projects (typically 20 to 30 years). However, the misapplication of stainless steel, which can lead to premature corrosion, continues to be a costly and common problem. Engineers and owners lack the resources to understand how to properly select these materials and specify the appropriate methods for their construction. The central objective of this project was to develop guidelines for water and desalination engineers to help them:
  1. Understand the types of stainless steel used for different applications based upon water quality considerations.
  2. Properly specify construction standards that, if followed, will help extend the useful life of stainless steel materials to a period greater than 20 years.
  3. Identify appropriate operating conditions such that stainless steel corrosion can be avoided to the greatest extent possible.
