Starting with the product itself, our high-purity stainless steel coiled tubes are made from premium 316L or 304L grades, ensuring ultra-low impurity levels that go beyond standard alloys. We refine the steel to minimize elements like sulfur and phosphorus, which can cause issues in medical environments. This results in tubes with exceptional corrosion resistance, thanks to the high chromium and molybdenum content. Our coiling process allows for precise diameters—ranging from 0.5mm to 10mm—and wall thicknesses as thin as 0.1mm, all while maintaining seamless integrity. What sets them apart is the biocompatible finish: we use advanced electropolishing to create a mirror-like surface that reduces friction and prevents bacterial buildup. These tubes are fully compliant with standards like ASTM A269, ISO 10993, and USP Class VI, making them safe for direct contact with blood, tissues, or pharmaceuticals. Whether you're dealing with fluid transfer or intricate surgical tools, our high-purity stainless steel coiled tubes deliver reliability without compromise.
