Seamless Stainless Steel Micro Tube is manufactured through our stringent cold drawing process providing high dimensional accuracy and smooth outer/inner surface along with good mechanical strength & resistance against corrosion. Micro tubes (micro tubing) are smaller stainless steel tubes that come with considerably smaller dimensions as per the specific requirements of the sector and they have tighter manufacturing tolerances.

They are used in various industries such as medical device, analytical instrumentation system, laboratory equipment, aerospace, hydraulic system, heat exchangers, semiconductor equipment and other precision applications.

We are a proficient manufacturer, supplier, and distributor of the cold drawn seamless stainless steel micro tubes and are available with the complete series of sizes, wall thickness and the grades of stainless steels, which we assure by providing extreme precision in all of our tubes and products.

What Are Stainless Steel Seamless Micro Tubes?

Stainless steel seamless micro tubes are very small diameter custom made precision tubes that are produced from solid stainless steel billets and do not contain a welded seam. In seamless tubing production, it has better structure than welded tubing, since there is not a potential failure area at a weld.

These tubes are commonly produced through cold drawing and precision sizing techniques, resulting in:
