1. Internal Wall: Conductive & Oil‑Resistant Coatings
- Specialized oil‑resistant, conductive epoxy coatings – isolate metal from oil‑induced corrosion and safely dissipate static electricity.
- Rigorous abrasive blasting prior to application; primer and topcoat thickness must meet specifications.
- Forms robust anti‑corrosive barrier for internal tank walls.
2. External Wall: Heavy‑Duty Coating Systems
- Primer + intermediate coat + topcoat system – epoxy zinc‑rich primer for cathodic protection; micaceous iron oxide for impermeable barrier.
- Highly weather‑resistant aliphatic polyurethane or fluorocarbon topcoat as outer armor.
- Ensures long‑term gloss, color retention, and resistance to UV, rain, and salt spray.
3. Tank Bottom Reinforcement & Cathodic Protection
- Thick‑film epoxy glass flake coatings – physical barrier against saline water accumulation.
- Install sacrificial anodes (aluminum or zinc‑based) on external or internal bottom surfaces.
- Electrochemical protection completely halts corrosion process in critical zone.
4. Summer Protection: Thermal Insulation & Radiation Resistance
- Radiation‑resistant, sun‑blocking coatings – reflect solar radiant heat to lower tank surface and internal temperatures.
- Suppresses "small breathing" phenomenon and reduces diesel evaporation.
- Mitigates fire risk and prevents accelerated coating aging from high‑temperature, high‑humidity environments.
