—— SHOMEA Medical-Grade 316L Stainless Steel Tubing ——

1. Medical-Grade Material for Ultimate Purity & Safety

Manufactured from 316L surgical-grade stainless steel, compliant with ASTM F138 / ISO 5832-1 international standards. The material offers exceptional biocompatibility, corrosion resistance against bodily fluids, and strictly controlled ion leaching, meeting the high-purity requirements for long-term implantation or single-use disposable devices.

2. Ultra-Precision Cold Drawing & Grinding for Dimensional Consistency

The tubing undergoes multi-pass cold drawing and inner diameter (ID) honing processes, ensuring uniform wall thickness. Dimensional tolerances are strictly controlled within ±0.01mm. This high geometric precision guarantees zero-gap fitting during connections, eliminating risks of leakage or loosening in critical assemblies.

3. Full-Length Electropolished Surface for Sterility

Both the inner and outer surfaces undergo electrolytic mirror polishing, achieving a surface roughness of Ra ≤ 0.4μm. The smooth, non-adherent surface facilitates complete drainage and effortless flushing, effectively inhibiting the formation of bacterial biofilms and complying with stringent hospital sterilization protocols.

4. Superior Mechanical Strength & Pressure Resistance

While maintaining high surface finish quality, the tubing retains high tensile strength and torque resistance. It is engineered to withstand high-pressure fluid surges and mechanical bending without developing micro-cracks or deformation, ensuring operational safety and longevity in clinical environments.
