Frequently Asked Questions
Stainless steel capillary tubes are used in various industries including:
- Medical devices (catheters, surgical instruments)
- Automotive (fuel lines, brake systems)
- Aerospace (hydraulic systems, instrumentation)
- Chemical processing (corrosive fluid transport)
- Instrumentation and laboratory equipment
Yes, Baobin specializes in custom manufacturing. We can produce capillary tubes with specific outer diameters, wall thicknesses, and lengths to meet your exact requirements. Our minimum order quantities are flexible to accommodate both small and large production runs.
Both grades offer excellent corrosion resistance, but 316 stainless steel contains molybdenum which provides superior resistance to pitting and crevice corrosion, especially in chloride environments. 316 is often preferred for medical and marine applications where higher corrosion resistance is required.
Standard lead time for our stainless steel capillary tubes is 7-14 working days. For custom orders or larger quantities, lead times may vary. We recommend contacting our sales team for specific delivery schedules based on your requirements.
