Product Structure

Double-Layer Shell: Consists of an inner primary containment tank and an outer secondary protective shell, creating an interstitial monitoring space.
Reinforced Saddle Bases: Heavy-duty steel supports that ensure stable weight distribution and prevent structural shifting.
Integrated Nozzle Array: Multiple top ports for specialized functions including fuel inlet, discharge, emergency venting, and vapor recovery.
Monitoring Manway: Large-diameter access ports for internal inspection, equipped with high-tensile bolt-sealing flanges.
Lifting Lugs: Strategically placed reinforced eyelets for safe and balanced crane transport and positioning.
Leak Detection Port: A dedicated interface for electronic or mechanical interstitial leak sensors.

Product Advantages

Secondary Containment: The double-wall design eliminates the need for expensive concrete dikes or bund walls, as the outer shell acts as a built-in containment system.
Superior Corrosion Resistance: Treated with a high-performance industrial red anti-corrosive coating to prevent rust and chemical degradation.
Environmental Safety: Specifically engineered to prevent soil and groundwater contamination, meeting strict environmental compliance standards.
Structural Durability: Constructed using automated longitudinal and circumferential welding techniques for maximum seam integrity.
Versatile Configuration: The manifold system can be customized with various flange sizes to match existing piping and instrumentation.
