Application Advantages

Tantalum seamless tubes are highly valued for their superior corrosion resistance, high melting point, and mechanical durability. They are ideal for use in extreme chemical, thermal, and vacuum environments, where conventional materials cannot perform reliably.

Key Application Advantages:

Exceptional Corrosion Resistance: Resistant to nearly all acids, including hydrochloric acid, nitric acid, and sulfuric acid, even at high concentrations.
High-Temperature Stability: Performs continuously up to 3000°C in vacuum or inert gas conditions.
Excellent Formability: Superior ductility and toughness allow deep drawing and complex shaping.
Non-reactive Surface: Chemically inert and biocompatible—suitable for medical and analytical instruments.
Long Service Life: Outstanding wear resistance and oxidation resistance minimize maintenance costs.

Typical Applications:

Chemical process equipment and heat exchangers
Cathode protection and acid-resistant tubing systems
Semiconductor manufacturing and vacuum furnace components
Medical and laboratory instruments
Aerospace propulsion and high-temperature reactor assemblies

Be used in a wide range of industries.

Manufacturing & Process Flow

At Shaanxi Chuanghui Daye Metal Material Co., Ltd., tantalum seamless tubes are manufactured through precision-controlled processes ensuring high purity, dimensional accuracy, and consistent mechanical performance.

Process Flow:

Raw Material Selection: 99.95%–99.99% high-purity tantalum ingots conforming to ASTM B521 or ASTM B365.
Vacuum Melting: Electron beam or powder metallurgy refining ensures minimal gas impurities.
Billet Forging: Multi-step hot forging for grain refinement and uniform structure.
Extrusion & Piercing: Controlled hot extrusion followed by mandrel piercing to form the hollow tube.
Cold Drawing: Multiple cold drawing passes with intermediate annealing to achieve final dimensions.
Heat Treatment: Vacuum annealing for stress relief and microstructure optimization.
Surface Finishing: Chemical polishing, mechanical grinding, or pickling for smooth internal/external surfaces.
Final Inspection: Comprehensive dimensional, mechanical, and purity testing before shipment.

Each stage is supervised by qualified metallurgists to ensure the final tube meets tight dimensional tolerances and surface smoothness standards.
