Stainless steel capilary tube used as medical needle

Completely different from large diameter stainless steel tube, stainless steel capillary tube is very small like blood vessel or any small diameter tube. A stainless steel tube is just a really thin tube. (Usually about 1/2 mm across on the inside) They are common and are frequently used in precision optical machine, industrial sensors, electronic equipment, circuit protection tube; chemical industry and medical field.

Stainless steel capillary tube mainly by the hot-rolled steel production, in addition to hot-rolled, there are perforated using hot or cold drawing process after the cold-rolled stainless steel sheet production of small size.

While most people may not understand the actual physical phenomenon that makes capillary tubing work, research engineers most certainly will.

Medical industry is one of the main applications for stainless steel capillary tube, especially for medical needle, which is widely used in the medical industry nowadays. The raw material is made of high quality stainless steel, and can be used in veterinary range, also supply many specs of pipes for medical needles.
