ISO9626 SUS304 SUS316L Stainless Steel Welded Capillary Tube For Medical Device Accessories
The ISO9626 SUS304/SUS316L stainless steel welded capillary tube is a high-precision thin-wall tubular product manufactured via precision welding and cold drawing process, exclusively customized for medical device accessory production. It features ultra-small outer diameter, ultra-thin wall thickness, strict dimensional consistency, excellent biocompatibility and sterilization resistance, and is the core raw material for manufacturing medical needle tubes, catheters, minimally invasive surgical accessories and precision medical fluid delivery components. Different from industrial ordinary capillary tubes, this medical-grade welded capillary tube fully complies with ISO9626 mandatory indicators, undergoes strict impurity control and surface purification treatment, contains no harmful precipitation substances, and adapts to high-frequency medical disinfection and human body contact scenarios, meeting medical safety and long-term stability requirements.
- SUS304 material is suitable for low-corrosion, short-term human contact medical devices. It is the preferred material for ordinary medical needle tubes, common infusion accessories and routine diagnostic instrument pipelines.
- SUS316L material is suitable for long-term implantation in human body, invasive minimally invasive surgery equipment and high-precision medical accessories with strict corrosion resistance requirements, and is recognized as the most reliable medical stainless steel capillary material in the industry.
Key Features of ISO9626 Medical-Grade 304/316L Capillary Tubes:
- Ultra-High Dimensional Precision
- Superior Corrosion Resistance & Durability
- Good Processability
- Excellent Biocompatibility & Safety
