Product Overview
Tantalum tube is manufactured from high-purity tantalum (Ta) through processes including vacuum electron beam melting, forging, rolling, and drawing. Common grades include R05200, R05400, Ta1, Ta10W, and Ta2.5W, covering diameter ranges of 0-150 mm, wall thicknesses of 0.1-5 mm, and lengths of 10-6000 mm. Available in cold-rolled bright finish (hard or annealed condition), seamless, or welded configurations.

Key Advantages & Features
High Temperature Resistance: Melting point near 3000°C enables long-term operation in extreme high-temperature environments
Exceptional Corrosion Resistance: Minimal corrosion rates in concentrated acids, strong alkalis, chlorides, and liquid metals
Good Ductility: Moderate hardness allows drawing into fine wires or thin-walled tubes, facilitating complex shape fabrication
Low Thermal Expansion Coefficient: Minimal dimensional changes ideal for precision instruments requiring high dimensional stability
Uniform Wall Thickness & Smooth Inner Surface (cold-rolled bright finish) enhances fluid transport and heat exchange efficiency
Customizable Specifications: Available from micro-capillary tubes to large-diameter heat exchange tubes with short lead times and controlled costs

Selection & Usage Guidelines
Corrosion Resistance Requirements: Prioritize high-purity (≥99.95%) pure tantalum or low-alloy tantalum (e.g., Ta1, Ta2.5W) for optimal acid/alkali resistance
High-Temperature Strength Requirements: For operating temperatures above 800°C, recommend unannealed hard-condition tantalum tubes (tensile strength 600-1400 MPa) to ensure adequate strength margin
Dimensional Precision: For heat exchangers requiring high wall thickness uniformity, select cold-rolled bright finish tubing with outer diameter tolerances up to ±0.01 mm (≤20 mm)
Fabrication Methods: For welding applications, recommend hard-condition thin-walled tubes with surface degreasing and preheating before welding to minimize weld crack risk (welding represents a potential weakness)
