Manufacturing range:
Stainless steel capillary, stainless steel small tube is widely used in medical treatment, fiber-optic, pen making, electronic welding products, light cable joint, food, vintage, dairy, drink, pharmacy and biochemistry, different length can be provided according to requests
Capillary tubes with a maximum bore of 0.0158 in., available in a wide range of stainless steels. Sandvik capillary tubes are characterized by tight tolerances, 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.
Stainless steel Coiled tubing is available in a range of different product forms depending on the customer requirements. Licancheng sihe stainless steel material manufactures welded and seamless tube products. The standard grades are 304 304L 316L(UNS S31603) Duplex 2205 (UNS S32205 & S31803) Super Duplex 2507 (UNS S32750) Incoloy 825 (UNS N08825) Inconel 625 (UNS N06625) Other grades of stainless steel in duplex and superduplex and nickel alloy are available on request.
