Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) stands at the forefront of the global energy sector as a premier Welded Steel Aviation Fuel Tank Manufacturer. Jet fuel (Jet A, Jet A-1, and increasingly Sustainable Aviation Fuel, SAF) powers global air travel, making the integrity and purity of its storage paramount to passenger safety, national security, and operational reliability. Storing aviation fuel demands a containment solution that is engineered to an entirely different level of precision, requiring absolute zero contamination, stringent material and coating compatibility, robust structural integrity against external forces, and unwavering adherence to the most exacting international standards (API, EI, JIG, and NFPA codes).
Our specialization is in fabricating high-integrity, customized Welded Steel Tanks that are indispensable for airport terminals, pipeline hubs, and military installations globally. Our expertise is concentrated on delivering tanks that achieve superior internal cleanliness, precise fluid handling systems to mitigate water and particulates, verifiable structural strength, and strict compliance with global aviation fuel handling standards. Through rigorous quality control, mastery of automated welding techniques, and specialized internal coating expertise, our tanks are assets of maximum purity, reliability, and long-term service life, safeguarding the fuel quality required for critical aviation operations.
Aviation fuel is unique in the energy spectrum due to the catastrophic consequences of contamination. The storage requirements for a Welded Steel Aviation Fuel Tank are defined by safety, purity, and regulatory mandate.
Purity is Non-Negotiable: The presence of contaminants—even trace amounts of water, rust particles, sediment, or incompatible chemicals—can freeze at high altitudes, block filters, or damage delicate engine components. The tank must be designed to eliminate internal corrosion sources and facilitate the complete removal of any water or sediment.
Safety and Fire Suppression: Aviation fuel is highly flammable. The Welded Steel Tanks must be engineered with advanced fire prevention features, including specialized foam-delivery systems, adequate ventilation, and structural resilience to external thermal loads, often adhering to National Fire Protection Association (NFPA) standards.
Mitigation of Corrosion Sources: While jet fuel itself is not highly corrosive, the presence of microbiologically influenced corrosion (MIC) and free water at the tank bottom poses a constant threat. The tank design must proactively manage water accumulation and ensure the internal surface is inert.
Regulatory Oversight (EI and JIG Standards): Aviation fuel storage is governed by incredibly strict industry bodies like the Energy Institute (EI) and the Joint Inspection Group (JIG). Compliance with these detailed requirements regarding tank bottom design, coating selection, internal smoothness, and filtration integration is mandatory for global terminal operations.
Center Enamel focuses on providing this combination of structural excellence and absolute purity protection through an API-centric, aviation-focused engineering approach.
The fabrication of Welded Steel Aviation Fuel Tanks is defined by an extreme emphasis on internal cleanliness, fluid separation, and verifiable structural integrity.
The internal environment must be pristine to prevent fuel contamination.
Non-Reactive Internal Coatings: We utilize specialized, high-solids, non-reactive internal epoxy coating systems that are certified as compatible with aviation fuels (Jet A/A-1) and, increasingly, with modern Sustainable Aviation Fuels (SAF). The application process is rigorously controlled to achieve an immaculate, smooth finish that minimizes sediment trapping and prevents chemical leaching.
Elimination of Internal Impurities: The fabrication process includes specialized cleaning and surface preparation techniques to ensure the internal surface of the Welded Steel Tanks is free from mill scale, welding slag, and residual fabrication debris before coating application.
High-Grade Steel and NDT: We use certified, high-grade steel plate, fabricated using automated welding to ensure full-penetration, defect-free seams. Every critical weld is subjected to exhaustive Non-Destructive Testing (NDT)—including radiographic and ultrasonic examination—to confirm structural integrity and prevent any minute flaws that could compromise containment.
Controlling water accumulation is the primary defense against corrosion and microbial growth.
Precision Sloped Bottom Design: The tank floor is engineered with an acute and precise slope (steeper than standard oil tanks) leading to a dedicated low-point sump or water draw-off boot. This design ensures that any free water that settles out of the fuel is quickly and efficiently channeled for sampling and removal, a critical requirement under JIG guidelines.
Water Draw-Off and Sampling: The tank structure is fabricated with reinforced nozzles designed for the installation of specialized draw-off pipes and sampling systems, allowing terminal operators to frequently test and remove free water from the lowest point of the Welded Steel Aviation Fuel Tank.
Internal Smoothness and Sediment Control: The interior welding and surface finishing minimize rough edges or pockets where sediment (such as rust or particulates) can accumulate and evade the draw-off systems, ensuring maximum efficiency of downstream filtration.
The tanks must withstand external threats while ensuring personnel safety.
External Fire Protection Integration: The tank structure includes provisions for the seamless integration of sophisticated fire suppression systems, such as deluge cooling systems and high-expansion foam delivery equipment, designed to meet rigorous NFPA and local fire safety codes.
Reinforced Access and Safety Platforms: Custom-fabricated access platforms, stairways, and ladders are welded to the tank, providing safe, compliant access to the roof for gauging and monitoring vital functions like pressure/vacuum relief valves.
Seismic and Wind Load Engineering: The large, vertical Welded Steel Tanks are rigorously engineered to resist catastrophic failure under maximum wind loads and seismic events, securing the fuel supply continuity and preventing environmental release.
The specialized design and high standards of our Welded Steel Aviation Fuel Tanks are essential across various critical aviation and defense nodes:
Major Airport Storage Farms: Large-scale tanks are located at commercial airport terminals, providing the main storage for Jet A/A-1 that is then fed to the hydrant system for aircraft refueling. Purity and high flow rates are paramount here.
Pipeline Terminal Hubs: Tanks situated at pipeline breaks or junctions store massive inventory of aviation fuel being transported across vast distances. These tanks are critical to maintaining the logistics supply chain stability.
Military Airbases: Storage of specialized jet fuels (e.g., JP-8) for defense applications, requiring extremely robust construction, physical security integrations, and strict adherence to military fueling standards.
Sustainable Aviation Fuel (SAF) Production: Increasingly, our tanks are being engineered for SAF storage, often requiring stainless steel or specialized internal finishes to handle the unique chemical profile of these next-generation fuels while maintaining ultra-high purity.
Aviation Fuel Depots and Distribution Centers: Smaller tanks used for intermediate storage before final delivery to regional airports or specialized consumers, focusing on reliable batch segregation and quality control.
Our capability as a specialized Welded Steel Aviation Fuel Tank Manufacturer is founded on a deep understanding of the industry's zero-tolerance policy for fuel quality compromise.
JIG/EI-Centric Design Philosophy: Our engineering team possesses expertise in the specific requirements laid out by the Joint Inspection Group (JIG) and the Energy Institute (EI), ensuring that our tank designs are compliant with global best practices for jet fuel handling, minimizing client risk and accelerating terminal certification.
Purity-Driven Fabrication: We employ unique internal fabrication protocols focused on cleanliness, including specialized surface preparation and the flawless application of aviation-grade internal coatings, which directly addresses the core mission of Welded Steel Aviation Fuel Tanks: fuel preservation.
Verifiable Integrity: Our strict adherence to API standards, coupled with comprehensive NDT testing of every critical weld, provides verifiable proof of structural integrity, a crucial document for regulatory and insurance purposes in the high-stakes aviation sector.
