In the aviation sector, the integrity of the fuel storage system is a matter of absolute safety. As a premier Welded Steel Aviation Fuel Tank Manufacturer, Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd) specializes in zero-contamination containment solutions for Jet A, Jet A-1, and Sustainable Aviation Fuel (SAF).
Our tanks are engineered to exceed the most exacting international standards—including API 650, EI 1541, JIG 1 & 2, and NFPA 407—safeguarding the critical fuel reserves required for airport terminals, pipeline hubs, and military airbases globally.
To ensure zero-contamination fuel delivery, our fabrication process is governed by a strict matrix of global safety and quality protocols.
Standard | Focus Area | Engineering Impact |
API 650 | Structural Integrity | Governs plate thickness and seismic/wind load resistance. |
EI 1541 | Coating Chemistry | Ensures internal linings do not shed particulates or react with SAF. |
JIG 1 & 2 | Operational Purity | Standards for tank bottom slope and "Clear & Bright" sampling. |
NFPA 407 | Fire Safety | Sets requirements for foam systems and aircraft servicing safety. |
The internal coating is the primary defense against corrosion and fuel degradation. At Center Enamel, we utilize a multi-stage application process in a strictly monitored, climate-controlled environment.
● Surface Preparation (Sa 2.5): Abrasive blasting to a "Near-White Metal" finish with a 50–75 micron anchor profile.
● Climate Control: We maintain Relative Humidity (RH) < 85% and steel temperatures at least 3°C above dew point to prevent flash rusting.
● Quality Validation: Every tank undergoes Digital DFT Gauging, High-Voltage Holiday Detection (Spark Testing), and ASTM Adhesion Testing to ensure a 100% holiday-free surface.
With the aviation industry's pivot toward Net Zero 2050, storage systems must handle Sustainable Aviation Fuel (SAF) blends like HEFA-SPK. Our tanks are engineered to be 100% SAF-ready, featuring:
● Aromatic Resistance: Maintaining structural stability against synthetic paraffinic kerosine (SPK).
● Non-Leaching Integrity: Coatings are tested to ensure they do not interact with SAF chemical markers, preserving "drop-in" fuel certifications.
Effective contamination management requires the immediate removal of water and sediment. Our tanks feature a precision-engineered Coned-Down Bottom.
● 1:30 (3.3%) Degree of Slope: An aggressive incline that ensures all particulates and water droplets migrate instantly to the center.
● Low-Point Sump Interface: A deep, stainless steel sump equipped with a dedicated sample line allows for daily "Clear & Bright" checks at the absolute lowest point of the tank.
● Zero-Ledge Fabrication: All internal floor welds are ground flush to eliminate pockets where microbial growth (Cladosporium resinae) could occur.
To maintain EI 1541 coating integrity, we recommend a strict operational schedule to prevent the development of tank sludge and Microbiologically Influenced Corrosion (MIC).
● Daily: Draw 5L from the low-point drain for water/sediment sampling.
● Monthly: Conduct microbial growth tests using specialized field kits.
● 5–10 Years: Perform professional internal "Man-Entry" cleaning.
○ Note: Use only rubber squeegees and non-metallic tools to protect the epoxy lining.
From high-volume commercial airport fuel farms to remote military installations, Center Enamel provides the structural resilience and purity-driven fabrication required for:
● Major Airport Storage Farms: Supplying high-hydrant systems with certified Jet A-1.
● Military Airbases: Engineered for the storage of JP-8 with integrated physical security.
● Pipeline Terminal Hubs: Massive inventory storage for logistics supply chain stability.
Our role as a leading Welded Steel Aviation Fuel Tank Manufacturer is defined by our mastery of automated welding and specialized coating application. By partnering with us, airport authorities and fuel consortiums secure a 30-year infrastructure asset that simplifies global terminal certification and guarantees fuel purity.
