Corrosion Prevention
How self-bunded tanks prevent corrosion through material selection, design, and protective treatments
Self-bunded tanks prevent corrosion through a combination of thoughtful material selection, structural design, and protective treatments that shield the tank from factors causing metal degradation.
Corrosion Prevention Methods
Material Selection
- Corrosion-Resistant Metals: Use of alloys that naturally resist reaction with water, oxygen, and stored liquids
- Inherent Properties: Materials that slow or stop electrochemical processes leading to rust
- Structural Integrity: Maintains tank strength even when in contact with corrosive substances
Double-Wall Structure
- Environmental Barrier: Outer wall protects against rain, snow, and soil moisture
- Dry Interstitial Space: Designed to remain dry or equipped with moisture removal systems
- Hidden Degradation Prevention: Reduces corrosion risk on vulnerable surfaces between walls
Protective Coatings & Linings
- Specialized Coatings: Create physical barriers between metal and corrosive elements
- Multi-Purpose Protection: Chemical-resistant, waterproof, and UV-resistant treatments
- Non-Metallic Linings: Impervious materials for highly corrosive liquids
Monitoring & Maintenance
- Inspection Ports: Allow operators to check for early signs of corrosion
- Detection Systems: Monitor changes in material condition and alert operators
- Early Intervention: Prevents small issues from developing into major problems
This multi-layered approach ensures the tank remains durable and corrosion-free, extending its lifespan and maintaining reliability for storing various liquids.
