Fire-Resistant Tank Design Features
Self Bunded Diesel Fuel Storage Tanks employ a combination of design features, material properties, and safety systems to pass stringent fire tests.
The inner tank stores diesel while the outer bund acts as secondary containment, preventing fuel leakage during fires.
- Non-combustible insulation between walls slows heat transfer
- Contains potential leaks within the bund structure
- Reduces risk of fire spread to surrounding areas
- Meets secondary containment regulations
High melting point withstands prolonged high temperatures
Maintains structural integrity during fire exposure
Fire-resistant paints form insulating char layers
Reduces flame spread across surfaces
- Pressure relief valves prevent tank explosions
- Flame arrestors on vents stop flame propagation
- Emergency shut-off systems isolate fuel supply
- Automatic fire suppression system compatibility
Regular inspection and testing of all fire protection components is essential to ensure system reliability. This includes valve functionality checks, coating integrity assessments, and emergency system drills.
These integrated design features enable tanks to meet international fire test standards including:
- UL 142 (Steel Aboveground Tanks for Flammable Liquids)
- EN 13530 (Cryogenic vessels - Large transportable vacuum insulated vessels)
- API 650 (Welded Steel Tanks for Oil Storage)
- NFPA 30 (Flammable and Combustible Liquids Code)
