Stainless steel capillary tubes

Stainless steel capillary tubes

Ruimai produce and supply capillary tubes in a wide range of austenitic stainless steel grades and duplex / super duplex stainless steel grades. 

Capillary tubes produced by Ruimai are characterized by precision tolerances, supplied in bright annealed condition and the inside surface of the tubes is free from oil, grease and other particles. This ensures, for example, an optimized and even flow of liquids and gases from the sensor to the measuring instrument.
