The SS Capillary Tube Seamless is used in unique applications like resist jets in the aerospace industry. The Stainless Steel Capillary Tubing has to be seamless and precise in dimensions with very less absolute roughness. The fluid flow has to be maintained uniformly throughout the operation time. The different material grades correspond to the application types. The 316 Stainless Steel Capillary Tubing is used in applications where 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 SS Capillary Tubing is of superior quality and we produce variations of these products. 316 Stainless Steel Capillary Tubing For HPLC is used for liquid chromatography and the SS Evaporator Coil Capillary Tube is used as an evaporator coil in various applications. You can contact us for various standard and customized product requirements.

Products that require consistent material throughout the tubing mostly use SS Capillary Tube Seamless. This is because the Stainless Steel Capillary Tubing is made up of a single piece of steel. This provides a continuous uninterrupted grain structure. Welds and mechanical finishes in 316 Stainless Steel Capillary Tubing create discontinuity in these pipes. This encourages crevice corrosion and mechanical failure in Stainless Steel 1/16 In. Capillary Tubing. The passive protective layer is formed by high-quality 1/16 Capillary Tubing that protects it from oxidation.

316 SS Capillary Tubing layer can be affected by poor heat treatment and welding. This happens due to the change in the chemical composition of the SS Evaporator Coil Capillary Tube in the heat-affected area. Apart from 316 Stainless Steel Capillary Tubing For HPLC they are also used in UPLC tubing, remote seal pressure transmitter tube, hydraulic tube, and sheath tubing. Stainless Steel Precision Tubing manufactured by us is not only used in machines and in industries they are also used as Medical Capillary Tube.

Stainless Steel Medical Tubing Grade

Grade Material
303 Stainless Steel Bar Stock: High in Corrosion resistance: Typically used in automatic machining operations.
304 Stainless Steel Tubing: Good in Corrosion resistance: Most widely used stainless steel with good formability and can be readily welded.
304L Stainless Steel Tubing: Good in Corrosion resistance: Offers better weld-ability than standard 304 Stainless Steel.
316 Stainless Steel Tubing: Better in Corrosion resistance: Offers higher strength at higher temperature than 304 Stainless Steel. Often used for pumps, valves, marine applications, and chemical equipment.
316L Stainless Steel Tubing: Better in Corrosion resistance:Offers better weld-ability than standard 316 Stainless Steel.
321 Stainless Steel Tubing:  Good in Corrosion resistance: Most similar to 304 Stainless Steel but with the addition of Titanium making it an excellent choice for prolonged, high temperature applications.
347 Stainless Steel Tubing: High in Corrosion resistance: High resistance to prolonged heat and corrosion applications. This is well suited for power generation and engine applications.
430 Stainless Steel Tubing: Good in Corrosion resistance:Combines good corrosion and heat resistance with good mechanical properties. Oxidation resistant to 1500 deg F and is used in many industrial and consumer products.
