Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) is a recognized global leader in containment solutions, operating as a premier Above Ground Fuel Storage Tanks Manufacturer. These storage vessels—often massive in scale—are the most visible and critical link in the petroleum and chemical supply chain, storing everything from crude oil and refined gasoline to diesel, jet fuel, and biofuels. The exposed nature of Above Ground Fuel Storage Tanks (ASTs) necessitates that they be engineered for the highest standard of uncompromising structural integrity against all external forces (including wind, snow, and seismic activity), rigorous corrosion defense, precise fluid management for purity, and unwavering adherence to the most stringent international safety and environmental codes (API, UL, NFPA, and local regulatory mandates).
Our expertise is concentrated on fabricating customized Above Ground Fuel Storage Tanks that set the industry benchmark for durability and operational performance across refineries, pipeline terminals, power generation sites, and large distribution centers. We focus on delivering solutions that integrate superior structural strength (calculated according to specific site conditions), advanced internal and external corrosion protection systems, specialized features for vapor and contamination control (such as floating roofs and sloped floors), and strict adherence to major international construction codes. Through rigorous quality control, mastery of automated welding techniques, and depth of material science knowledge, our Welded Steel Tanks are essential assets of maximum reliability, safety, and long-term service life, safeguarding the critical supply chain of global energy infrastructure.
Above Ground Fuel Storage Tanks present unique engineering challenges due to their exposed location and the hazardous nature of the stored liquids. Addressing these factors precisely is the core mission of a dedicated Above Ground Fuel Storage Tanks Manufacturer.
Structural Resilience to Environmental Loads: ASTs must withstand a continuous array of external stresses, including high winds, snow accumulation on the roof, and the dynamic forces generated by seismic events. The design must rigorously follow the API 650 standard (the primary global code for atmospheric storage tanks), ensuring proper shell thickness, wind girder placement, and robust anchorage systems are specified based on the tank's exact geographical location.
Corrosion Mitigation (Internal and External): ASTs are susceptible to two main forms of corrosion. External Atmospheric Corrosion attacks the shell and roof, necessitating high-performance, multi-layered coating systems. Internal Corrosion typically occurs at the tank bottom due to the settlement of water and acidic contaminants, requiring sloped floors, sumps, and sometimes cathodic protection or internal linings.
Vapor and Emission Management: For volatile products like gasoline and crude oil, controlling vapor loss is vital for both economic loss prevention and meeting strict environmental regulations concerning Volatile Organic Compound (VOC) emissions. This challenge often requires the specialized fabrication and integration of internal or external floating roof systems.
Contamination Control and Fuel Purity: Maintaining the quality of the stored fuel requires tank designs that actively prevent the ingress of external contaminants (rain, dust) and allow for the efficient management and removal of internal contaminants (water, sludge, sediment) through features like precision sloped bottoms and dedicated draw-off sumps.
Safety and Containment: Due to the large volumes stored, primary containment integrity is critical. Furthermore, many jurisdictions require secondary containment (such as concrete berms or liners) to be integrated into the tank's foundation or surrounding area to catch any potential spill, a factor the tank design must accommodate.
Our engineering approach centers on providing this combination of structural endurance, advanced safety features, and verifiable quality assurance through our mastery of Welded Steel Tanks fabrication.
The manufacturing process for Center Enamel's Above Ground Fuel Storage Tanks is a large-scale, precision operation focused on achieving flawless containment and compliance with API and UL standards.
Structural excellence is the non-negotiable foundation of AST safety and longevity.
API Standard Adherence: Our tanks are overwhelmingly designed and fabricated in strict accordance with API Standard 650 for vertically cylindrical, atmospheric storage tanks. This involves meticulous calculation of shell thickness, material selection of certified, high-grade carbon steel, and dynamic load modeling for the specified service life.
Automated and Verified Welding: Center Enamel employs state-of-the-art automated welding systems (including submerged arc welding) for both circumferential and vertical shell seams, as well as floor and roof plates. This automation guarantees a consistent, full-penetration, defect-free weld, creating a unified, monolithic structure that stands up to decades of hydrostatic load.
Non-Destructive Testing (NDT): Prior to and during construction, every critical weld and plate material is subjected to rigorous Non-Destructive Testing (NDT)—such as ultrasonic testing, magnetic particle inspection, and radiographic examination—to confirm structural integrity. This provides the auditable quality documentation required for regulatory approval and certification worldwide.
Protecting the steel from its operating environment is paramount for asset life cycle management.
External Coating Systems: The exposed shell and roof surfaces receive multi-layered, industrial-grade external coating systems, selected based on the operating environment (e.g., coastal, industrial, or arid). These systems resist atmospheric corrosion, ultraviolet degradation, and chemical splash, providing the primary defense for the steel structure.
Internal Corrosion Mitigation: To combat corrosion at the base, the tank floor is fabricated with a sloped bottom leading to a dedicated sump or draw-off boot. This design actively prevents the accumulation of free water, which is the catalyst for corrosion and microbial growth. Specialized internal coatings or bottom plate materials may also be utilized for enhanced protection.
Foundation and Underside Protection: The tank's foundation often incorporates corrosion-mitigating elements, and our design can accommodate the integration of under-tank cathodic protection systems (either sacrificial anodes or impressed current), ensuring the hidden underside of the floor plate is actively protected from soil-side corrosion.
The design must incorporate specialized features to manage the inherent risks of storing flammable and combustible liquids.
Vapor Control Systems: For high-volatility fuels, we manufacture and integrate Internal Floating Roofs (IFRs) or External Floating Roofs (EFRs). These structures float on the liquid surface, significantly reducing the vapor space, cutting evaporative product loss, and minimizing the risk of vapor ignition, thereby meeting stringent air quality and safety codes. .
Fire Safety Provisions: The tanks are designed and fabricated with reinforced connection points for the integration of fire safety equipment, including foam delivery systems, deluge cooling piping, and emergency relief venting that meet rigorous NFPA and local fire safety codes.
Venting and Pressure Relief: Tanks are equipped with precision-calibrated pressure/vacuum (P/V) relief valves and emergency vents. These devices are critical for preventing structural damage (rupture or collapse) caused by sudden internal pressure fluctuations from temperature changes or rapid filling/emptying operations.
