ISO9626 SUS304 , Stainless Steel Coiled Capillary Tube For Medical Needle Tube Manufacturing
The Stainless Steel Capillary Tube is a specialized product designed for high precision applications, combining material properties, manufacturing standards, and functional design. This capillary tube is used in various applications, like medical devices(needle tubes), precision instruments, sewing industry, jewelry Industry, and so on. Stainless steel capillary tubes can be made in straight type or coiled type, and these tubes are mainly produced by stainless steel 304/304L, 316/316L grades. Due to the different applications, stainless steel capillary tubes have different standards. For example, when it's used for medical device, it should comply with ISO9626: 2016 standard. And it should accord with ASTM A269/A213 specification when the capillary tube is used for common industrial applications. YUHONG GROUP manufactures bright annealed stainless steel capillary tubes with a variety of sizes to meet different clients' demand. If the client has special requests for the shape of capillary tubes, we can also customize it.
Definition & Key Features:
- Capillary Tubes: Characterized by a small inner diameter, designed for precise fluid or gas control.
- Coiled Design: Pre-formed into compact coils for easy storage, installation, and routing in confined spaces.
- Material: Made from austenitic stainless steel grades (e.g., 304, 316, 316L) for corrosion resistance, durability, and hygiene.
Standards For Different Application & Testing:
1.Standards: Complies with ISO 9626 (medical tubes & precision tubes), ASTM A269/A213 (stainless/welded industrial tubes)
2.Testing:
- Pressure/Leak Testing: Ensures integrity under operational stress.
- Dimensional Checks: Strict tolerances for OD, ID, and wall thickness.
- Surface Inspection: Smooth finish verified via microscopy or profilometry.
Advantages Of Stainless Steel Capillary Tubes:
- Corrosion Resistance: Suitable for harsh environments (e.g., saline, chemicals).
- High-Temperature Tolerance: Retains properties under thermal stress.
- Flexibility: Coiling allows easy installation in complex layouts.
- Hygienic Surface: Electropolished or passivated finishes prevent contamination (critical for medical/lab use).
Key Applications:
- Medical: Endoscopes, catheters, IV lines, and gas delivery systems (sterility and flexibility critical).
- Industrial: HVAC refrigerant lines, automotive fuel systems, and chemical instrumentation.
- Laboratory: Chromatography, fluid metering, and analytical equipment.
