Stainless Steel Seamless Capillary Tube

The Capillary Tube Seamless is used in widely used for automation instrument, wire protection tube,precision optical ruler line,industrial sensors,etc. The Stainless Steel Capillary Tubing has to be seamless and be precise in dimensions with very less absolute roughness. The fluid flow has to be maintained uniform throughout the operation time. The different material grades correspond to the application types. The 316 Stainless Steel Capillary Tubing is used in applications where the corrosion resistance is much needed. There are different sizes of capillary tubing such as the Stainless Steel 1/16 In. Capillary Tubing and the 1/16 Capillary Tubing. The sizes are also determined by the application type and requirements. Our 316 Capillary Tubing is of superior quality and we produce variations of these products. 316 Stainless Steel Capillary Tubing For Hplc is used for the liquid chromatography and the Evaporator Coil Capillary Tube is used as evaporator coil in various applications.
