How to Prevent Corrosion in Storage Oil Tanks

2025-11-15 Leave a message

Tank Surface Protection

  • Regularly clean the surface of the tank to remove dust, oil, and corrosive deposits, keeping the appearance clean and dry.
  • If rust, scratches, or coating damage are found, promptly grind and remove the rust, and apply a suitable anti-corrosion coating evenly to form an effective protective barrier.
  • Avoid direct contact between the tank surface and sharp objects or rough surfaces to prevent coating damage and corrosion, ensuring the surface protective layer remains intact.

Internal Media Control

  • The stored media must meet the tank material compatibility requirements; avoid using highly corrosive media.
  • Regularly empty the tank of residual media and thoroughly clean internal deposits and impurities to prevent long-term adhesion and internal wall corrosion.
  • After cleaning, ensure the tank is completely dry to prevent moisture from reacting with the media.
  • Do not mix different types of media that may cause corrosion.

Storage Environment

  • When placing or using the tank, choose a dry, well-ventilated, flat, and firm location, away from damp areas and corrosive gases or liquids.
  • Avoid prolonged exposure of the tank to direct sunlight and rain; take shading and moisture-proof measures to mitigate the corrosive effects of environmental factors.
  • Keep away from areas containing corrosive substances such as acids and alkalis to prevent contact corrosion and ensure the surrounding environment is free of corrosion hazards.

Regular Inspection & Maintenance

  • Regularly inspect the condition of the anti-corrosion coating, checking for peeling, cracks, etc., and promptly repair any damage by recoating.
  • Inspect welds, joints, and other easily corroded areas. Address any rust immediately to prevent further corrosion.
  • Regularly inspect sealing components to ensure they are intact and prevent moisture and impurities from entering and causing internal corrosion.
  • Maintain accurate maintenance records to create a complete maintenance loop.
