Corrosion Risk Planning for Storage Tank

Risk Planning activity for a Storage Tank

What should form an integral part of a quality management system which includes corrosion risk planning for a tank?

What areas should one look at when planning for design/maintenance/inspection of a tank?

1.Inner walls – Risk :
Coating degradation
Corrosion due to water/dissolved oxygen

2. Outer walls/roof – Risk :
Atmospheric corrosion
coating degradation due to moisture + UV radiation + temperature

3. Pipes – Risk :
Atmospheric corrosion
Coating degradation

4. Railing – Risk :
Coating degradation
Wrong coating selection based on pure aesthetics
coating damage at joints and bends

5. Breather valve – Risk :
uniform corrosion/pitting depending on whether it is made up of carbon steel/stainless steel
Galvanic couple at the joining/welding point of valve to roof
