How do you fix pitting corrosion?

Fixing pitting corrosion involves several steps to remove the damaged areas and prevent further deterioration. Here are effective methods to address pitting corrosion:

  1. Alloy Selection: Choose alloys with higher PREN values like 316 stainless steel for better resistance.
  2. Design Practices: Optimize designs to minimize crevices and promote proper drainage to reduce stagnation.
  3. Barrier Coatings: Use coatings like paints, epoxies, or Armoloy to protect metal surfaces from corrosive environments.

Preventive Maintenance:

  • Conduct regular inspections to detect early signs of pitting corrosion.
  • Apply corrosion inhibitors to protect susceptible metals.
  • Ensure proper drainage and avoid stagnant water or corrosive deposits.

By following these steps, you can effectively repair pitting corrosion and extend the lifespan of your metal components.
