1. Inner Tank Pressure Design Standards
- Primary inner vessel capacity – engineered to withstand minimum design pressure of 0.8 MPa for skid‑mounted refueling devices.
- Construction strictly adheres to national and international pressure vessel safety regulations.
- Ensures safe handling of dynamic forces from stored liquids.
2. Outer Shell Atmospheric Pressure Tolerance
- Secondary outer shell – designed for atmospheric pressure conditions, not high internal pressure.
- Functions as robust secondary containment barrier.
- Withstands interstitial monitoring fluid pressure without deformation.
- Capable of containing accidental leaks from inner tank.
3. Interstitial Space Pressure Monitoring Limits
- Critical pressure management zone – excess fluid pressure must be strictly controlled.
- Standard limit: should not exceed 0.001 MPa.
- Continuous monitoring is essential – unexpected increases serve as early warning of inner tank breach.
4. Aviation & Extreme Dynamic Pressure Testing
- Rigorous aviation standards – must withstand extreme internal pressures (tested to 24.2 kPa / 3.5 psi or 125% of max ram air pressure).
- Exhaustive vibration and dynamic load testing simulates maximum acceleration.
- Ensures safe endurance under severe operational stresses without rupture or leakage.
