The Above ground fuel storage tank (AST) represents a critical choice in fuel infrastructure, favored by many operators for its inherent accessibility and simplified maintenance regime compared to underground systems. An AST's design must compensate for its visibility and exposure by incorporating specialized features for fire resistance, spill prevention, and structural stability against external forces. A failure in an Above ground fuel storage tank can lead to immediate operational disruption, fire risk, and significant environmental exposure.
Above ground fuel storage tank systems demand a design that is robust, versatile, and highly focused on readily verifiable safety, requiring exceptional attention to:
Integrated Safety and Fire Rating: The design must often include built-in secondary containment (double walls) and, in critical areas, fire-resistant construction to meet strict local and international fire codes.
Structural Resilience: Tanks must be engineered to withstand environmental stresses, including wind, seismic forces, and thermal expansion/contraction.
Corrosion Protection: Exposed surfaces require superior coating systems to resist weathering, UV degradation, and industrial atmosphere corrosion.
The globally recognized solution for secure, visible, and high-volume fuel containment is the custom-engineered welded steel tank. Its monolithic structure provides the necessary structural rigidity to handle internal hydrostatic pressure and external loads, while its versatility allows for the integration of essential safety features like double walls and sophisticated access points.
Shijiazhuang Zhengzhong Technology Co., Ltd, known globally as Center Enamel, leverages its extensive experience in large-scale steel fabrication and specialized quality management to excel as a China Above ground fuel storage tank Manufacturer. We deliver custom-engineered welded steel tanks that strictly adhere to relevant international codes, such as those set by Underwriters Laboratories (UL) and the American Petroleum Institute (API), ensuring our clients receive assets engineered for maximum accessibility, compliance, and operational reliability.
The design and manufacture of an Above ground fuel storage tank are driven by the need for visible integrity, environmental security, and robustness against external elements. Our expertise in specialized welded tank fabrication ensures every critical aspect is addressed, guaranteeing reliability across diverse commercial, industrial, and strategic environments.
Integrated secondary containment is the most effective modern safety feature for an Above ground fuel storage tank, simplifying environmental compliance by eliminating the need for large external concrete dikes in many jurisdictions.
Coaxial Welded Construction: We manufacture the tank using a primary internal welded steel shell and a concentric outer welded steel shell. This design creates a continuous, sealed interstitial space between the two walls, which serves as the secondary containment barrier.
Factory-Certified Leak Detection: This interstitial space is designed to be monitored continuously using electronic sensors or hydrostatic pressure. Should the primary wall fail, the secondary wall provides immediate containment, and the monitoring system triggers an instant alarm. This proactive detection is vital for rapid response and minimizing environmental impact.
Fire-Resistant Options: For tanks requiring enhanced fire protection, we utilize specialized designs, often involving a precise layer of fire-resistant material within the double-wall space. This construction enables the tank to meet standards like UL and significantly increases the tank’s endurance during adjacent fire events.
An AST must be inherently robust to withstand natural and operational forces throughout its life.
Wind and Seismic Engineering: Unlike underground tanks, ASTs are fully exposed. Our engineering process includes rigorous analysis to ensure the welded tank is anchored and structurally sound to resist high wind speeds and comply with regional seismic codes. This prevents overturning or structural deformation, which are critical safety concerns for tall, large-diameter tanks.
Robust Shell and Bottom Design: The welded steel shell and bottom plates are fabricated and joined using advanced, controlled welding procedures. The tank bottom is particularly crucial, often featuring a slight slope to facilitate water draw-off and is designed for appropriate foundation support, mitigating settlement stress.
Thermal Management and Venting: ASTs are subject to significant solar heat gain. Tanks are designed with appropriate coatings (often reflective) and correctly sized vents and emergency venting mechanisms. These are vital for safely managing the pressure fluctuations caused by temperature changes, preventing potential structural damage from over-pressurization.
The exterior visibility of an Above ground fuel storage tank means its external protection system must be durable, high-performance, and aesthetically sound.
Exterior Protective Coatings: Tank exteriors receive multi-layer, high-performance coating systems (e.g., epoxy primers and polyurethane topcoats). These systems are chosen for their superior resistance to UV exposure, weathering, and industrial atmosphere corrosion, ensuring the structural steel shell is protected for decades.
Water and Sediment Management (Internal): The presence of water and sediment within the stored fuel can cause internal corrosion. Tanks are designed with sloped floors and strategically located sumps to facilitate the collection and safe removal of settled water, preserving both the tank's integrity and the fuel's quality.
Foundation Corrosion Control: The steel bottom plate resting on the concrete foundation requires specific protection. This is achieved through corrosion barriers, specialized membranes, and cathodic protection systems to prevent moisture ingress and resulting bottom-plate corrosion.
The advantage of an AST is its accessibility, which we capitalize on by integrating features that simplify maintenance, inspection, and operation.
Access Platforms and Walkways: Tanks are fabricated with strategically located nozzles and fittings for fuel transfer, gauges, and safety devices. Furthermore, for large vertical tanks, we design and install compliant stairs, ladders, and peripheral walkways, ensuring safe and easy access for required inspection, maintenance, and product sampling.
Instrumentation Ports: Tanks are manufactured with dedicated ports for the easy installation of essential monitoring equipment, including continuous level gauges, temperature probes, overfill prevention devices, and electronic leak detectors, all of which are essential for ongoing compliance.
Blending and Circulation: For commercial operators, tanks are often equipped with ports to facilitate external blending or internal circulation systems, ensuring a homogeneous product before distribution, particularly important for blended diesel or fuel additives.
