Product Description
Technical details, material information and manufacturing notes for this product.
Tantalum Tube / Pipe Overview
Tantalum tubes and pipes are high-performance fluid transport materials.
They are designed for extremely corrosive and high-temperature environments.
They provide safe and stable handling of aggressive chemical media.
Compared with steel or titanium, tantalum offers near-total chemical inertness.
It is widely used in chemical plants and pharmaceutical systems.
It ensures zero leakage risk under extreme operating conditions.
1. Manufacturing Types (ASTM B521 Standard)
Seamless Tantalum Tubes
Manufactured by gun-drilling or cold drawing from solid billets.
No weld seams, ensuring maximum strength and pressure resistance.
Ideal for high-pressure and ultra-pure chemical systems.
Welded Tantalum Tubes
Formed by rolling sheet and welding longitudinal seams.
Lower cost and suitable for large diameter applications.
Used in heat exchangers and moderate pressure systems.
2. Key Engineering Properties
Extreme Corrosion Resistance
Tantalum resists almost all acids including nitric and sulfuric acid.
Only hydrofluoric acid can attack its protective oxide layer.
Excellent Thermal Conductivity
Unlike ceramics or glass, tantalum transfers heat efficiently.
It maintains performance under extreme temperature conditions.
Zero Contamination Surface
Self-healing Ta2O5 layer prevents fouling and scaling.
Ensures high purity in pharmaceutical and semiconductor systems.
3. Common Material Grades (UNS)
| Grade | Material | Application Benefit |
| R05200 | Pure Tantalum (Melted) | Maximum ductility and corrosion resistance |
| R05400 | Pure Tantalum (Sintered) | Uniform grain structure for electronics |
| R05252 | Ta-2.5W Alloy | High strength for heat exchangers |
| R05255 | Ta-10W Alloy | High-temperature aerospace applications |
4. Industrial Applications
Chemical Heat Exchangers
Used in bayonet heaters and condenser systems.
Handles aggressive acids in processing and recycling systems.
Thermowells & Protective Sheaths
Protects temperature sensors inside corrosive reactors.
Prevents direct acid contact and equipment failure.
Tantalum-Lined Steel Pipes
Combines steel strength with tantalum corrosion resistance.
Used in large-scale industrial pipeline systems.
