What is Capillary Stainless Steel Tube?
Stainless steel capillaries are tiny, thin-walled stainless steel tubes. Typically ranging in diameter from a few millimeters to a few microns, they are made from stainless steel through precision drawing and machining processes. Simply put, they resemble miniature stainless steel tubes. Capillary stainless steel tubes are highly precise, smooth, and strong, making them ideal for transporting liquids, gases, or wires in confined spaces where performance is critical. They are widely used in medical devices, precision instrumentation, and industrial equipment.
advantages of Capillary Stainless Steel Tube
High Corrosion Resistance
Made from stainless steel such as 304, 316, or 316L, these products offer strong resistance to rust, chemicals, and marine environments.
High Dimensional Precision
Manufactured to tight tolerances, these products ensure precise outer diameters, inner diameters, and wall thicknesses, ensuring reliable fit and performance in precision systems.
High Temperature Resistance
Our products withstand high temperatures and maintain excellent physical and chemical properties, making them suitable for transferring high-temperature fluids or operating in high-temperature equipment.
Long Service Life
Our products are resistant to wear, thermal cycling, and environmental degradation, ensuring a long service life with minimal maintenance.

Stainless Steel Capillary Tube Production Process
Raw Material Selection: Choose high-quality stainless steel billets or coils (grades like 304, 316, 316L) to ensure corrosion resistance, strength, and cleanliness.
Tube Formation: The stainless steel is cold-rolled or cold-drawn into a smaller diameter tube, gradually reducing the size while maintaining wall thickness accuracy.
Cold Drawing & Sizing: Multiple cold drawing passes are performed through precision dies to achieve the required outer diameter, inner diameter, and wall thickness.
Annealing: Tubes are annealed in a controlled atmosphere furnace to restore ductility, relieve internal stresses, and improve corrosion resistance.
Pickling & Cleaning: Chemical pickling removes oxidation and surface impurities, ensuring a bright, smooth surface finish.
Straightening & Cutting: Tubes are straightened with high-precision machines and cut to required lengths or coiled for continuous supply.
Surface Finishing: Additional polishing or bright annealing may be applied to achieve a mirror-like finish for medical or decorative applications.
Quality Inspection & Testing: Perform dimensional checks using micrometers and gauges, eddy current testing for micro cracks, hydrostatic pressure testing to ensure leak tightness, and endoscopy to check internal surface quality.
Packaging: Tubes are packaged in protective wrapping, plastic caps, or coil reels to prevent contamination and mechanical damage during transport.
