Generally, the size of the rolled titanium capillary is the specification with the outer diameter greater than 2mm, and the length of the titanium capillary tube with the outer diameter greater than 2mm can be about 2m. The titanium capillary produced by the drawing process has an outer diameter of less than 2mm, and its length is generally less than 2m.     

However, in actual production, due to the small size of the titanium capillary required by some customers, for example, the titanium capillary with an outer diameter of about 1mm can achieve a length of 500-1000mm. Since the tube is too thin, bending is inevitable during polishing and handling, so the straightness of the titanium capillary  will decrease at this time.
