Frequently Asked Questions
Q
What is the minimum outer diameter available for precision thin tubes?
The minimum outer diameter for precision thin tubes in the regular specification range starts at 1.0mm. For customized orders, the outer diameter can go as small as 0.5mm, depending on your specific application requirements.
Q
What tolerance standards do your tubes comply with?
All tubes are manufactured in compliance with the ASTM B394 standard. Precision thin tubes offer outer diameter tolerances of ±0.002mm — ±0.01mm and wall thickness tolerances of ±0.001mm — ±0.005mm. Standard/thick tubes offer outer diameter tolerances of ±0.01mm — ±0.1mm and wall thickness tolerances of ±0.005mm — ±0.05mm.
Q
Can I request a custom length for the tubes?
Yes. Custom lengths are fully supported. The maximum single-piece length available is 8000mm. Fixed-length cutting services are also available to meet your precise project requirements.
Q
What surface roughness options are available?
For precision thin tubes, inner/outer polished surfaces achieve Ra≤0.2μm and bright annealed surfaces achieve Ra≤0.8μm. For standard/thick tubes, polished surfaces achieve Ra≤0.4μm and bright annealed surfaces achieve Ra≤1.0μm. Custom roughness levels are available on request to ensure optimal fluid transportation performance.
Q
Is it possible to customize both wall thickness and outer diameter simultaneously?
Absolutely. Both outer diameter (0.5mm — 200mm) and wall thickness (0.1mm — 20mm) can be customized simultaneously according to your design specifications. Our engineering team will work with you to ensure the combination meets your structural and performance needs.
Q
Are these tubes suitable for high-end equipment assembly requiring tight tolerances?
Yes. Our precision-grade tolerance customization is specifically designed for high-end equipment assembly. We can achieve ultra-tight tolerances on both outer diameter and wall thickness, ensuring reliable fit and performance in demanding industrial, medical, or aerospace applications.
