GR5 Titanium Alloy Seamless Pipe for Aviation Oil Pipeline Aircraft auxiliary oil pipe
1. Why use titanium alloy to make aviation fuel pipes?
Titanium alloy has the following advantages, which are particularly suitable for the aviation field:
Light weight: about 40% lighter than steel, weight reduction is the key to aircraft design.
Super corrosion resistance: can resist aviation fuel, water vapor, and salt spray corrosion.
High strength: The strength is close to that of steel, much higher than aluminum, and has strong pressure resistance and explosion resistance.
High and low temperature resistance: can withstand extreme environments from -250°C to 600°C.
Good fatigue performance: long-term work in high pressure and vibration environment, not easy to crack and fail.
Extremely long life: the service life is much longer than traditional carbon steel or aluminum alloy fuel pipes.
Therefore, titanium alloy fuel pipes are mostly used for:
Aircraft main fuel pipelines, engine peripheral fuel pipelines, and internal pipelines of high-end refueling equipment.
2. Common materials for titanium alloy aviation oil pipes
Material code Full name Characteristics
Ti-6Al-4V Titanium-6% aluminum-4% vanadium alloy Most commonly used, high comprehensive strength,
good corrosion resistance, suitable for molding
Ti-3Al-2.5V Titanium-3% aluminum-2.5% vanadium alloy More suitable for cold processing and thin-walled oil pipes
Gr.2 pure titanium Industrial pure titanium Average strength, but excellent corrosion resistance, suitable for low-pressure systems
3. Titanium alloy oil pipe manufacturing process
Seamless titanium pipe manufacturing: hot extrusion + cold rolling/cold drawing to ensure that the pipe wall is uniform and defect-free.
Welded titanium pipe manufacturing: laser welding after titanium strip forming, suitable for large diameter pipes.
Surface treatment:
Pickling to remove oxide layer
Passivation treatment to prevent later corrosion
Precision size control:
Pipe diameter tolerance is generally controlled within ±0.1mm
Pipe wall thickness tolerance ±10%
4. Typical performance indicators (taking Ti-6Al-4V as an example)
Tensile strength: ≥895 MPa
Yield strength: ≥828 MPa
Elongation: ≥10%
Hardness: 280～340 HV
Density: about 4.43 g/cm³ (40% lower than steel)
