Key Grade & Process Explanation
Steel Grades for Aircraft Fuel Systems: ASTM A53 Gr.B and 20# high-purity carbon steel are the core grades for DN100 aircraft fuel ERW pipes. A53 Gr.B features a minimum yield strength of 240MPa, tensile strength of 415-540MPa, and elongation ≥20%, with extremely low sulfur (≤0.035%) and phosphorus (≤0.035%) content-critical for preventing aviation fuel contamination and corrosion. 20# steel offers excellent low-temperature toughness and weldability, adapting to the temperature variation (-40℃ to 60℃) of airport fuel systems. X42 grade provides higher strength (yield strength ≥290MPa) for high-pressure fuel transmission lines (working pressure 8-10MPa), ensuring safety during aircraft refueling.
ERW Process for Aviation Fuel Advantages: Advanced high-frequency ERW technology, using high-quality steel strips formed into a cylinder and welded with electric resistance welding, ensures uniform and defect-free weld seams. The weld seam undergoes online annealing (850-900℃) to eliminate internal stress, making its mechanical properties consistent with the base metal-critical for preventing fuel leakage in high-pressure systems. The process also enables ultra-precise dimensional accuracy (outer diameter tolerance ±0.3mm), facilitating seamless connection with aviation fuel valves, refueling arms, and filters, reducing on-site installation errors and safety risks.
Aircraft Fuel Special Design: Optimized for aviation fuel safety, with strict control of non-metallic inclusions to avoid fuel contamination. The pipe's smooth inner surface (Ra ≤12.5μm) reduces fuel flow resistance and prevents impurity deposition, ensuring fuel purity (compliant with Jet A-1 standards). Anti-static conductive coating (surface resistance 10⁶-10⁹Ω) is applied to eliminate static electricity generated by fuel flow, preventing spark risks in flammable aviation fuel environments. Optional FBE anti-corrosion coating enhances resistance to soil corrosion and aviation fuel corrosion, adapting to underground airport fuel line burial conditions.
