Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), recognized as a leading China Carbon Steel Aviation Fuel Tank Manufacturer, provides containment solutions that operate at the highest level of stringency and verifiable safety required by the global aerospace and defense industries. Aviation fuel—comprising Jet A/A-1 (a kerosene-based combustible liquid) and Avgas (aviation gasoline, a highly volatile flammable liquid)—is the lifeblood of flight. The storage of these specialized fuels presents a dual challenge: ensuring absolute purity to prevent critical engine failure and guaranteeing uncompromising safety due to flammability and high regulatory oversight. The vessels used, the Carbon Steel Aviation Fuel Tank, must be meticulously engineered and fabricated to ensure precision water and contamination control, advanced systems for fire safety and emission reduction, verifiable structural integrity, and unwavering adherence to the most demanding international codes, including API 650, UL 142/2085, and relevant NFPA and ICAO regulations.
Our expertise is concentrated on fabricating customized Carbon Steel Aviation Fuel Tank solutions that set the industry benchmark for purity control, structural compliance, and long-term operational excellence across major international airports, regional airfields, military bases, and specialized refueling depots. We focus on delivering solutions that integrate superior structural strength, specialized features for de-watering and filtration, advanced corrosion protection systems, and strict adherence to major international construction codes. Through meticulous engineering, rigorous quality control, mastery of automated welding techniques, and depth of material science knowledge, our Welded Carbon Steel Tanks are essential assets of maximum reliability, uncompromised fuel quality, and long-term service life, securing the most safety-critical storage segment of the global fuel supply chain.
The non-negotiable requirement for aviation fuel storage is the preservation of fuel quality. Contamination—particularly water, sediment, and particulates—can precipitate freezing in high-altitude flight or damage sensitive aircraft components, leading to catastrophic failure. As a specialized China Carbon Steel Aviation Fuel Tank Manufacturer, Center Enamel focuses on integrated design solutions that prioritize this purity.
Purity Control (Water and Particulate Management): Aviation fuel, especially Jet A, is highly susceptible to holding suspended water and is extremely sensitive to sediment. The tank design must integrate features like precision sloped bottoms, dedicated sumps, and reinforced ports for high-efficiency filtration and coalescer systems to ensure the fuel remains within strict purity specifications (e.g., those set by ASTM).
Structural Integrity and Code Compliance: Tanks must maintain exceptional stability, adhering to API Standard 650 for large, field-erected terminals or UL 142 or UL 2085 (fire-rated) for smaller, above-ground commercial facilities. Adherence to these codes is non-negotiable for highly regulated aerospace assets.
Corrosion Mitigation and Lining: While Jet A fuel is generally non-corrosive to carbon steel, the water phase is highly corrosive. Furthermore, the tank requires specialized internal coatings or linings to create a non-reactive barrier that prevents rust or mill scale from contaminating the fuel, which is crucial for maintaining cleanliness standards.
Vapor and Fire Safety: For Avgas (aviation gasoline), volatility control and specialized emergency venting systems are essential due to its low flash point. For all aviation fuels, the structure must be designed to integrate fire suppression systems and anti-static grounding measures required by NFPA codes.
Aluminum Dome Roofs: A robust, fixed roof is required to protect the contents and insulation system. Aluminum Dome Roofs are utilized in these large-scale applications to provide a superior, lightweight, and corrosion-resistant external structure that ensures thermal stability and guards against environmental ingress that could compromise the fuel's quality.
Our expertise ensures that every Welded Carbon Steel Tank is engineered for both the heavy-duty containment and the specialized purity, safety, and regulatory requirements of aviation fuel storage.
The manufacturing process utilized by Center Enamel for the Carbon Steel Aviation Fuel Tank is a high-specification operation, concentrated on achieving the structural excellence and functional design required for preserving fuel quality and maximizing safety.
Structural reliability is critical, as any failure has high-stakes consequences.
API Standard 650 Adherence: Large capacity Carbon Steel Aviation Fuel Tank solutions strictly follow API Standard 650 for vertical, cylindrical tanks. This dictates precise calculations for shell course thickness based on hydrostatic, seismic, and wind loads, ensuring verifiable stability and integrity.
Automated Welding and NDT Verification: Utilizing certified, high-grade carbon steel plates, our advanced automated welding systems ensure continuous, full-penetration, defect-free seams across the entire structure. Every critical weld on the Welded Carbon Steel Tanks undergoes rigorous Non Destructive Testing NDT—such as radiographic examination and ultrasonic testing—to confirm monolithic structural integrity, a non-negotiable requirement for high-load, high-safety containment.
UL Standards for Commercial/Protected Use: For smaller tanks and protected storage, we adhere to UL 142 and often UL 2085 (Protected Tanks, offering fire resistance and impact protection), guaranteeing compliance with key safety and fire protection standards required at airfields and commercial facilities.
Contamination control is engineered into the very structure of the tank floor and connections.
Sloped Bottom and Sump Design: Tank floors are fabricated with a precise sloped bottom leading to a dedicated, reinforced sump. This crucial feature ensures that any free water—the primary source of corrosion and microbial growth—is efficiently channeled away from the product and towards a specialized water draw-off point for removal. This design is paramount for maintaining the cleanliness and integrity of the Carbon Steel Aviation Fuel Tank.
Internal Linings and Coatings: To prevent minute corrosion products (rust flakes or mill scale) from entering the fuel stream, the internal carbon steel surface is meticulously prepared to receive specialized, non-reactive internal linings or coatings. These coatings provide a critical barrier that maintains the extremely high cleanliness standards demanded by aviation authorities.
Filtration and Sampling Ports: The tank structure is fabricated with reinforced, custom-sized connections tailored for the seamless integration of high-flow filtration systems, de-watering centrifuges, and product sampling probes, all necessary for continuous quality monitoring and control.
The roof choice ensures environmental protection and structural security for the safety-critical fluid.
Floating Roof Integration (for volatile Avgas): While less common for Jet A, where volatility is lower, for aviation gasoline (Avgas), the tank shell may be fabricated with the precision necessary to accommodate the sealing and function of an Internal Floating Roof (IFR), which is crucial for reducing vapor emissions and complying with NFPA standards for flammable liquids.
Aluminum Dome Roofs: For large capacity fixed-roof Carbon Steel Aviation Fuel Tank applications (including those with IFRs or where thermal stability is critical), we integrate corrosion-resistant, self-supporting Aluminum Dome Roofs. These lightweight domes provide a superior external seal, protecting the highly clean fuel from external environmental debris and moisture, and supporting heavy insulation systems necessary for temperature regulation. Aluminum Dome Roofs are utilized for their structural strength, minimal weight, and excellent anti-corrosion properties, ensuring long-term asset integrity.
The multi-layered approach to corrosion and safety ensures the longevity of the carbon steel structure and the security of the facility.
Internal protection is designed to prevent any degradation that could compromise fuel quality.
Corrosion Allowance and Material Grade: The carbon steel shell and floor plates are selected with a specified corrosion allowance—an extra thickness of steel—to account for the expected internal degradation over the multi-decade design life. High-quality steel grades are selected for superior strength and weldability.
Static and Bonding Features: The tank is fabricated with integrated grounding and bonding features to prevent the buildup of static electricity during fueling and de-fueling operations, which is a significant ignition risk for high-purity, low-conductivity aviation fuels.
External environmental defense and mandated secondary containment are essential safety requirements.
External Coating Systems: The tank exterior receives high-performance, multi-layered industrial coating systems specifically selected for superior resistance to atmospheric corrosion, UV degradation, and chemical exposure, ensuring the longevity of the Welded Carbon Steel Tanks shell.
Cathodic Protection Integration: The tank floor's underside (soil-side) is protected by designing the tank foundation interface to accommodate the seamless integration of cathodic protection systems (sacrificial anodes or impressed current). This continuous, long-term defense against external electrochemical corrosion is a non-negotiable requirement for environmentally critical aviation fuel storage.
Double-Wall and Diked Design (UL 2085): For smaller tanks, we fabricate specialized double-wall or diked structures, adhering to standards like UL 2085, providing an inherent layer of secondary containment and enhanced fire resistance to mitigate environmental and safety risks.
