Products Description
Our Advantages
1. High Corrosion Resistance
- Our tubing is made from high-quality stainless steel, such as 304 and 316L, with raw materials undergoing rigorous chemical composition testing to ensure material quality. It exhibits excellent resistance to body fluids, disinfectants, and sterilization chemicals.
- The tubing undergoes bright annealing and intergranular corrosion testing to ensure excellent corrosion resistance during repeated sterilization cycles involving steam autoclaving and chemical disinfectants.
2. Surface Quality
- Our Hospital Needle Medical Stainless Steel Tubes are bright annealed, pickled, and passivated, ensuring spotless inner and outer surfaces, free from contamination risks, and meeting hospital hygiene standards.
- The tubing undergoes precision polishing and surface roughness control, with Ra ≤ 0.4 μm, and finer roughness can be provided upon customer request.
3. High Precision
- Our Hospital Needle Medical Stainless Steel Tubes are manufactured through multiple precision cold drawing processes, resulting in strict dimensional tolerances. Outer diameter tolerance is controlled within ±0.005–0.01 mm, and wall thickness is ≤±5% mm.
- The tubing undergoes rigorous dimensional and visual inspection to ensure no dimensional deviations during needle grinding, beveling, or assembly.
4. Excellent Mechanical Properties
- Our tubing possesses excellent strength, ductility, and toughness, making it easy to bend and form without cracking during needle grinding and sharpening processes.
- The tubing undergoes rigorous mechanical property testing to ensure compliance with ASTM A269 standards and medical application requirements.
