Project Description

Ultra-Fine Stainless Steel Tubes for Medical Use

Overview:

Subcutaneous injection needles come in various sizes, with the outer diameter specified and the wall thickness and length indicated by actual measurements. Smaller gauge numbers represent larger outer diameters, and the inner diameter is determined by the gauge number and wall thickness. The following table shows the differences between standard wall (normal thickness) and thin wall (thin thickness) tubes. For the same outer diameter, thin-wall tubes have a larger inner diameter compared to standard wall tubes.
