1. Secondary Safety Barrier Against Leaks
- Unique dual‑layer structure – inner and outer shell create robust secondary barrier.
- Contains flammable fuel if inner tank is damaged or corroded.
- Eliminates fire or explosion risk from leakage at the source.
2. Prevents Environmental & Soil Contamination
- Vital line of defense – fully contains fuel within interstitial space during leaks.
- Prevents hazardous substances from seeping into soil or groundwater.
- Combined with online leak monitoring, ensures ecosystem safety.
3. Reduces Fuel Evaporation & Product Loss
- Tightly sealed structure – minimizes evaporative losses from vapor space.
- Internal floating roof technology further reduces losses.
- Conserves energy and lowers VOC emissions to reduce pollution.
4. Enhances Overall Structural Strength
- Superior physical strength – interstitial space acts as buffer for thermal insulation and corrosion resistance.
- Withstands external erosion and impacts (e.g., vehicle loads).
- Boosts pressure and seismic resistance, extending service life.
