The specification parameter system of titanium tubes is relatively complete, and titanium tube specifications mainly include the following key dimensions:
Dimensions
• Outer diameter range: usually φ3-200mm (larger sizes can be customized for special titanium tube specifications needs)
• Wall thickness range: 0.3-10mm (ultra-thin wall tubes can reach 0.1mm)
• Length standard: conventionally 6m/12m (supports customization of any length)
Material classification
• Industrial pure titanium series:
GR1 (TA1): highest purity titanium
GR2 (TA2): standard industrial pure titanium
• Titanium alloy series:
GR5 (TC4): Ti-6Al-4V alloy
GR7 (TA9): Ti-0.2Pd alloy
GR12 (TA10): Ti-0.3Mo-0.8Ni alloy
Standard system
• International general standards:
ASTM B338 (titanium tubes for heat exchangers)
ASTM B861 (titanium tubes for industrial use)
AMS 4941 (titanium alloy tubes for aviation use)
• Domestic standards:
GB/T 3624 (titanium and titanium alloy tubes for general industrial use)
GB/T 3625 (titanium and titanium alloy tubes for heat exchangers)
Special application specifications
• Medical grade: meets ASTM F67/F136 standards for implantable devices
• Aerospace grade: meets AMS 4941/4942 and other aviation material specifications
• Nuclear power grade: titanium tube specifications that meet the special requirements of the nuclear industry
Process parameters
• Tolerance grade: ordinary grade (±5%), precision grade (±2%)
• Surface treatment: pickled surface, polished surface (Ra0.8-3.2μm)
• Testing standards: 100% eddy current testing, ultrasonic testing, etc.
These specifications constitute a complete titanium tube specifications technical indicator system, which can meet the stringent requirements of different application scenarios, from precision medical equipment to large chemical equipment. Users can customize in terms of material selection, dimensional tolerance, surface treatment, etc., according to specific application requirements.
