1. Tank Roof Structure & Seal Maintenance
- Regular roof inspections – check welds, flanges, gauging ports; ensure sealing gaskets are intact, free from aging or cracking.
- Clear debris – remove leaves and debris to prevent standing water from damaging anti‑corrosion coating or seeping through gaps.
- Primary defense against rainwater ingress.
2. Breather Valve & Exhaust Vent Protection
- Rain and dust cover – install to prevent direct splashing into breather valve during heavy rain.
- Check flame arrester – ensure it is not obstructed by silt‑laden rainwater.
- Prevents over‑pressurization or tank collapse (implosion) from blocked airflow.
3. Containment Dike Drainage & Foundation Flood Protection
- Maintain dike integrity – keep containment wall in good condition; drainage valves tightly closed except during authorized operations.
- Clear drainage ditches – prevent rainwater from backing up into containment area during storms.
- Prevents prolonged immersion of tank base, avoiding severe corrosion.
4. Regular Drainage & Moisture Monitoring
- Increase drainage frequency – regularly drain accumulated water via tank‑bottom drain valve during rainy season.
- Monitor water level – use water‑finding paste or online moisture analyzer to track changes.
- Strictly prevents long‑term accumulation of free water at tank bottom.
