Product Structure
-
Inner Steel Layer: Fabricated from high-grade carbon steel (Q235B) to provide the primary structural framework and pressure resistance.
-
Outer FRP Layer: A secondary containment shell made of resin and glass fiber, providing a seamless, corrosion-proof barrier against external soil elements.
-
Interstitial Leak Detection Space: A permanent gap between the two layers, typically equipped with vacuum or liquid sensors for real-time monitoring.
-
Manway & Integrated Access: Heavy-duty manhole covers with flanged connections for filling, suction, and vapor recovery lines.
-
Lifting Lugs & Support Ribs: Strategically placed for secure transport, positioning, and structural reinforcement against burial loads.
Product Advantages
-
Environmental Safety: The double layer oil tank design with a leak detection system eliminates the risk of underground pollution.
-
Extreme Corrosion Resistance: The FRP outer shell is immune to electrochemical corrosion, common in underground soil environments.
-
Long Service Life: Engineered to last over 30–50 years with minimal maintenance compared to single-wall steel tanks.
-
Superior Structural Strength: The inner steel core handles high internal pressure and prevents deformation under the weight of the backfill.
-
Cost-Efficiency: Reduces long-term costs by avoiding expensive leak cleanups and frequent cathodic protection inspections.
