  1. 1. Corrosion and Scale
  2. 2. Pumps & Pipes 1 November 12, 2007 We Are Also In the Fluids Business Producing Transporting Storing Processing
  3. 3. Pumps & Pipes 1 November 12, 2007 Containment Integrity Unimpeded Flow With Similar Imperatives
  4. 4. Pumps & Pipes 1 November 12, 2007 Types of Corrosion General Localized Pitting Cracking
  5. 5. Causes of Corrosion and Cracking Electrochemistry Water Salt Low pH (CO 2 , H 2 S) Electrochemical cell Hydrogen embrittlement Load forces (stress) Embrittlement Hydrogen H2S Chlorides
  6. 6. Managing Corrosion Condition the fluids, keeping them non-corrosive pH control Method or Practice Example Non-corroding materials Corrosion resistant alloys Film forming inhibitors Water treating chemicals Coatings Paint, plastic linings Corrosion Coupons
  7. 7. Corrosion “Holy Grails” Corrosion free materials that are: <ul><li>As strong as carbon steel </li></ul><ul><li>Economic for very large projects </li></ul>Indestructible coatings: <ul><li>Impervious to everything </li></ul><ul><li>Will not scratch, chip, or tear </li></ul>Magic inhibitors: <ul><li>Effective at very small doses </li></ul><ul><li>Forming impervious barriers </li></ul>
