The general aviation sector, encompassing smaller aircraft with piston engines, relies entirely on avgas (aviation gasoline). This fuel is distinct from jet fuel and conventional automotive gasoline due to its extremely high octane rating, specific volatility requirements, and often the inclusion of tetraethyl lead (TEL) for engine performance. These unique properties make storing avgas in an Aviation gasoline (GAS) storage tank particularly challenging and critically important:
Lead Management: The presence of TEL requires specialized handling to prevent sediment buildup and maintain fuel quality.
High Volatility: Avgas is more volatile than jet fuel, demanding superior vapor control and stricter venting and pressure management systems to minimize evaporation loss and explosion risk.
Fuel Purity: As with all aviation fuels, the slightest contamination (water, particulates) can cause engine failure.
A failure in an Aviation gasoline (GAS) storage tank is a high-consequence event, risking fuel quality loss, environmental contamination, and operational shutdown for an airport.
Aviation gasoline (GAS) storage tank systems demand a design that is technologically advanced and purpose-built for volatility and purity management, requiring exceptional attention to:
Vapor and Pressure Control: Incorporating highly effective floating roof systems or robust pressure-rated construction to manage high volatility and explosive vapors.
Contamination Isolation: Designing the tank with internal features and coatings that prevent internal corrosion and facilitate the complete removal of water and sediment.
Strict Global Compliance: Adherence to specialized aviation standards (such as those from the Joint Inspection Group, JIG) and relevant fuel-specific codes.
The established, definitive solution for high-purity, volatile fuel containment is the custom-engineered, welded steel tank. Its monolithic structure provides the necessary structural resilience and versatility to integrate advanced vapor control systems, specialized linings, and high-security access points.
Shijiazhuang Zhengzhong Technology Co., Ltd, known globally as Center Enamel, leverages its deep expertise in specialized steel fabrication, advanced welding, and rigorous quality management to excel as a China Aviation gasoline (GAS) storage tank Manufacturer. We deliver custom-engineered welded steel tanks that strictly adhere to relevant international and aviation-specific codes, ensuring our clients receive storage assets engineered for maximum safety, product purity, and unparalleled operational reliability.
The design and manufacture of an Aviation gasoline (GAS) storage tank are fundamentally driven by the necessity of managing high volatility, preventing contamination, and ensuring long-term structural integrity. Our expertise in specialized welded tank fabrication ensures every critical aspect is addressed, guaranteeing reliability across general aviation airports and flight operations.
Avgas has a low flash point, making vapor control a primary safety and financial concern.
Vapor Management Systems: For large-volume storage, Internal Floating Roof (IFR) systems are often mandatory. The roof floats directly on the liquid surface, effectively eliminating the vapor space. This drastically reduces evaporative product loss (a significant cost factor due to high volatility) and minimizes the oxygen available to support combustion, thereby protecting safety and the environment.
Pressure Management and Venting: The tank is equipped with highly sensitive, correctly sized Pressure/Vacuum (P/V) relief vents. These devices are crucial for safely managing pressure fluctuations caused by temperature changes or rapid filling, preventing structural stress and ensuring vapors are safely controlled.
Grounding and Bonding: Comprehensive electrical grounding and bonding systems are integrated into the tank structure. These are essential for safely dissipating the static electricity generated during high-speed fueling and transfer operations, mitigating the risk of static-induced ignition of the highly volatile fuel vapors.
Maintaining avgas purity is essential for engine safety and longevity.
Internal Coatings and Corrosion: The interior of the welded tank is treated with specialized, high-performance internal linings that are chemically inert and designed to resist internal corrosion from water and sediment. These coatings are meticulously applied to prevent rust formation, which can quickly contaminate the fuel.
Sloped Floors and Sumps: Tanks are specifically designed with precision sloped floors leading to strategically positioned sumps and draw-off points. This gravitational design facilitates the rapid and complete collection and removal of free water (from condensation or transfer) and settled lead sediment, minimizing the risk of contamination and corrosion.
Filtration Interface: Tanks are designed to integrate seamlessly with the mandatory high-efficiency filtration and quality control equipment used in avgas transfer. This includes ports for quick-connect couplings to filter/separator units that remove particulates and trace water before the fuel is dispensed.
An Aviation gasoline (GAS) storage tank must provide absolute, long-term, verifiable containment integrity in compliance with environmental and safety codes.
Robust Welded Construction: We utilize certified, high-grade steel, processed and joined using advanced, automated welding procedures. The commitment to full-penetration, leak-proof welding on every seam ensures the monolithic welded tank structure provides a reliable, long-term barrier against hydrostatic pressure and external loads.
Double-Walled Options: For smaller commercial tanks used at local airports, double-walled aboveground (AST) or underground (UST) welded steel tanks are manufactured. This integrated system provides a monitored interstitial space, offering verifiable secondary containment and simplifying environmental permitting.
Rigorous Nondestructive Testing (NDT): All critical structural and containment welds are subjected to exhaustive NDT protocols (such as ultrasonic testing and magnetic particle inspection) to guarantee absolute integrity, which is paramount for safety and environmental protection.
The tank design must facilitate easy and frequent quality checks required for aviation fuel.
Sampling Ports and Manways: Tanks feature dedicated, secure ports for routine fuel sampling at various levels, as well as accessible manways for internal inspection and cleaning. This allows airport personnel to perform required quality checks (e.g., water checks, clear and bright tests) easily and safely.
Thermal Control: While not requiring cryogenic insulation, avgas tanks must be engineered to minimize excessive solar heat gain. External reflective coatings are often applied to maintain the fuel within specified temperature ranges, which is important for controlling volatility and evaporation.
Fire Safety Interfaces: Tanks are equipped with all necessary interfaces for sophisticated fire suppression equipment, including foam injection ports and emergency isolation valves (ESVs), ensuring rapid response capability in the event of an incident.
