Double Wall Fuel Tank Quality Assessment
Material Inspection
- Inner wall should be made of corrosion-resistant materials like high-grade steel or HDPE
- Must withstand long-term fuel exposure without degradation
- Outer wall requires robust durability and thickness consistency
- Should resist environmental stress (UV rays, temperature fluctuations)
Interstitial Space Design
- Properly sealed gap between walls is essential
- Should include leak detection ports or sensors
- System must allow for easy monitoring
- Early leak identification capability is crucial
