Product Dimensions and Tolerances

We maintain strict dimensional tolerances to ensure consistent quality:

• Outer Diameter Tolerance: ±0.1 mm
• Wall Thickness Tolerance: ±10%
• Length Tolerance: ±5 mm
• Straightness: Maximum 1 mm per meter
• Surface Roughness: Ra ≤ 1.6 μm

Product Features in Detail

The seamless construction of our tubes eliminates welded seams that could become failure points. Unlike welded alternatives, these tubes offer uniform wall thickness and consistent mechanical properties throughout their length. The natural oxide layer formation provides self-healing corrosion protection, making them ideal for harsh environments.

Quality Assurance and Testing

Every tube undergoes comprehensive quality testing:

• Chemical composition analysis
• Dimensional verification
• Surface quality inspection
• Mechanical property testing
• Pressure testing capabilities
• Non-destructive testing when required

FAQs

Q: What's the difference between seamless and welded tubes?

A: Seamless tubes have no welded joints, offering superior structural integrity and pressure resistance. They're manufactured through extrusion rather than welding processes.

Q: Can you provide small quantities for testing ?

A: Yes, we accommodate both small testing orders and large production runs.

Q: What certifications do you provide?

A: We provide material certifications, dimensional reports, and chemical analysis certificates with each shipment.

Q: How do I maintain these tubes?

A: Our tantalum alloy seamless tube products require minimal maintenance. Simple cleaning with mild soap and water is usually sufficient.
