product key technologies
Outer diameter classification and wall thickness design specifications
Ultra thin tube: Φ 1.0-5.0mm (wall thickness 0.1-0.5mm, high-precision sensor sleeve).
Conventional pipe: Φ 6-80mm (wall thickness 1.0-20mm, mainstream size for industrial structural components).
Large caliber pipe: Φ 100-203mm (wall thickness 5-30mm, specialized for semiconductor/nuclear power equipment).
Thick walled tube: Wall thickness ≥ outer diameter × 5% (for high-temperature pressure bearing components, such as rocket fuel tubes).
Thin walled tube: Wall thickness
Process characteristics and features
Forming process
Hot rolling perforation: Thick walled pipes (δ ≥ 5mm) are formed by vacuum melting ingots → hot rolling and opening → perforation molding (temperature ≥ 1000 ℃).
Extrusion cold drawing: Thin walled tubes (δ<5mm) are pre formed by extrusion → multi pass cold drawing (reduction rate ≤ 8%/pass).
Customization of ultra large caliber: For pipes with a diameter greater than 150mm, segmented welding and shaping processes are required.
Quality Control Core
Composition control: Niobium ≥ 99.95%, Hafnium 10 ± 1%, Titanium 1%.
Defect detection: Ultrasonic testing (GB/T8162 standard)+helium mass spectrometry leak detection (essential for vacuum tubes).
application area
Aerospace
- Rocket thruster fuel tube: a thick walled tube with a diameter of 25-80mm, capable of withstanding a pressure of ≥ 30MPa (resistant to 1500 ℃ gas erosion).
- High temperature sensor sleeve: Φ 1.0-3.0mm ultra-thin tube, coated with a silicide anti-oxidation layer on the surface (for monitoring combustion chamber conditions).
Energy and Nuclear Power
- Nuclear reactor conduit: Φ 50-100mm pipe, transporting liquid metal coolant (resistant to neutron radiation and corrosion).
- Fusion device vacuum chamber: large diameter tube with a diameter of 150-203mm, low thermal expansion coefficient to ensure dimensional stability.
High end industry
- Semiconductor equipment cavity: Replace quartz tube with a diameter of 100-203mm tube, which increases the high-temperature resistance life by three times.
- Chemical corrosion-resistant pipeline: inner wall polished Ra ≤ 0.8 μ m (to prevent high-purity acid residue).
Niobium hafnium alloy C103 pipes achieve full-size coverage of 1.0-203mm through a hot rolling cold drawing collaborative process. Its high-temperature strength (with 60% performance retention at 1500 ℃) and corrosion resistance are irreplaceable in fields such as aerospace and nuclear power.
In the future, with the integration of additive manufacturing technology, the efficiency of forming large-diameter pipes and the accuracy of thin-walled pipes are expected to break through existing bottlenecks.
