Frequently Asked Questions
Q
Can you customize the ends of the capillary tubes?
Yes. Because our core expertise includes Precision Turned Parts, we can customize the tube ends with threads, chamfers, flares, or custom grooves to fit your specific assembly requirements perfectly.
Q
What is the standard lead time for customized orders?
Our standard production cycle is typically 15 to 21 days. However, for urgent projects, our flexible production lines and strong R&D team can expedite the process upon request.
Q
Do you accept small batch orders for testing?
Absolutely. We support our clients from the R&D prototyping phase all the way to mass production. Please contact our engineering sales team to discuss your specific Minimum Order Quantity (MOQ) needs.
Q
How do you guarantee the quality of such small diameter tubes?
We employ rigorous inspection protocols, including dimensional checks using optical measurement systems, material composition analysis, and pressure testing (if required), ensuring every batch meets international standards (ASTM, DIN, etc.) and your exact tolerances.
Q
Which stainless steel grades are available for capillary tubes?
We offer a comprehensive range of grades including the full 300 Series (304, 304L, 316, 316L, 316Ti, 310S), as well as 201, 2205 duplex, and 2507 super duplex stainless steel. Our engineering team can recommend the optimal grade based on your application's corrosion resistance, temperature, and mechanical requirements.
