Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) is a specialized leader in containment solutions, operating as a premier Welded Steel Aviation Gasoline (GA) Storage Tank Manufacturer. Aviation Gasoline, or Avgas (typically 100LL), fuels the global fleet of piston-engine aircraft—ranging from personal planes to essential utility and agricultural aircraft. While smaller in volume compared to jet fuel, the storage of Avgas is equally, if not more, critical, demanding structures that guarantee absolute fuel purity, rigorous management of leaded content, prevention of volatility loss, and unwavering adherence to the most stringent international standards (including relevant FAA, NFPA, and UL codes).
Our expertise is concentrated on fabricating customized Welded Steel Tanks that are indispensable for fixed-base operators (FBOs), small regional airports, flight schools, and private hangars globally. We focus on delivering solutions that integrate superior internal cleanliness, precise fluid handling systems to mitigate water and particulates, verifiable structural strength, and strict compliance with the specialized codes governing leaded fuel handling. Through rigorous quality control, mastery of automated welding techniques, and internal coating specialization, our tanks are assets of maximum purity, reliability, and long-term service life, safeguarding the fuel quality for the general aviation sector.
Avgas presents unique challenges that differentiate its storage requirements from both jet fuel and motor gasoline. As a specialized Welded Steel Aviation Gasoline (GA) Storage Tank Manufacturer, Center Enamel addresses these nuances meticulously.
Purity and Contamination Control: Avgas, particularly 100LL (low lead), is extremely sensitive to contamination. The presence of water, rust, particulates, or especially incompatible chemicals can severely compromise engine performance and air safety. The tank must be designed to eliminate internal corrosion sources and facilitate the complete and frequent removal of free water and sediment.
Volatility and Vapor Pressure: Avgas is highly volatile. Stored at ambient temperature, vapor pressure must be managed to prevent excessive evaporation (product loss) and to ensure safe operation. The tank structure, along with its venting and piping, must be engineered to prevent vapor lock and excessive breathing losses, a key difference from less volatile jet fuels.
Leaded Fuel Management: While classified as "low lead," Avgas still contains tetraethyl lead (TEL). This requires specialized internal coatings and materials that resist chemical interaction with the lead compounds and prevent the accumulation of lead sludge, which can foul filters and transfer systems.
Regulatory Focus (FAA, UL): Due to its application in general aviation, storage solutions must comply with specific Federal Aviation Administration (FAA) guidelines for airport safety and often the stringent requirements of UL 142 (Standard for Steel Aboveground Tanks for Flammable and Combustible Liquids), particularly for smaller FBO installations.
Our engineering approach centers on providing this high level of purity assurance, structural excellence, and regulatory adherence essential for the general aviation sector.
The fabrication of Welded Steel Aviation Gasoline (GA) Storage Tanks is defined by an extreme emphasis on internal cleanliness, secure containment, and specialized fluid management features.
The internal environment must remain pristine to ensure the integrity of the leaded fuel.
Non-Reactive Internal Coatings: We utilize specialized, high-solids epoxy or zinc silicate internal coating systems that are certified as compatible with Avgas (100LL). The coating application process is rigorously controlled to achieve an immaculate, smooth finish that prevents lead compound adhesion (sludge formation) and minimizes sediment trapping.
Superior Steel and Monolithic Integrity: We use certified, high-grade steel plate, fabricated using automated welding techniques 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 the structural integrity and prevent any minute flaws that could compromise containment.
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 the protective coating application.
Controlling water accumulation and sludge is critical for preventing microbial growth and maintaining fuel quality.
Sloped Bottom and Sump Design: The tank floor is engineered with a gentle but precise slope leading to a dedicated low-point sump. This design ensures that any free water that settles out of the fuel, along with lead sludge, is efficiently channeled for sampling and removal, preventing corrosion and filter fouling.
Water Draw-Off and Sampling: The tank structure is fabricated with reinforced nozzles designed for the installation of specialized draw-off pipes, allowing FBO operators to frequently sample and remove contaminants from the tank’s lowest point.
Internal Access: Where applicable, specialized manways and internal access points are designed to facilitate periodic tank cleaning and inspection, which is more frequently required for leaded fuels to manage sludge accumulation.
The tanks must withstand external threats while ensuring fire safety, a paramount concern for volatile gasoline.
Venting for Volatility Control: The tank design incorporates specialized venting systems, including pressure/vacuum relief valves, to manage the high vapor pressure of Avgas, minimizing evaporation losses while preventing structural damage from pressure fluctuations.
Compliance with UL 142/NFPA 30: For many above-ground installations, the tanks are specifically designed and fabricated to meet the robust containment and construction requirements of UL 142 and NFPA 30 (Flammable and Combustible Liquids Code), ensuring safe installation at airfields.
Fire Protection Provisions: The tank structure includes provisions for the seamless integration of fire suppression systems, ensuring the site meets rigorous local fire safety codes, which are especially strict around aviation facilities.
The specialized design and high standards of our Welded Steel Aviation Gasoline (GA) Storage Tanks are essential across various critical aviation nodes:
Fixed-Base Operators (FBOs): The most common application, where tanks provide bulk storage for fueling services offered to general aviation aircraft at regional and local airports.
Small Regional Airports: Tanks serving as the primary fuel supply for smaller commercial, charter, and cargo operations that rely on piston-engine aircraft.
Flight Schools and Training Centers: Storage of Avgas for high-frequency use by a fleet of training aircraft, demanding consistent purity and high throughput reliability.
Agricultural and Utility Airbases: Used for bulk storage of fuel for crop dusters, fire surveillance aircraft, and other specialized utility aircraft that require quick refueling access.
Private and Corporate Hangars: Smaller, dedicated tanks for corporate flight departments or individual aircraft owners who require onsite, high-quality fuel storage.
Our capability as a specialized Welded Steel Aviation Gasoline (GA) Storage Tank Manufacturer is founded on a deep understanding of the unique requirements of storing a leaded, high-volatility fuel.
Purity-Driven Fabrication for Leaded Fuel: Our engineering protocols are uniquely adapted to Avgas, focusing on internal surfaces that resist lead sludge accumulation and chemical interaction, directly addressing the core mission of Welded Steel Aviation Gasoline (GA) Storage Tanks: product preservation.
