The Stainless Steel 316 Welded Capillary Tubes are high-precision small tubes that are produced through an advanced welding process using Grade 316 stainless steel strip. Grade 316 may be used to produce a high-quality alloy due to its ability to have molybdenum content between 2 to 3%; the alloy has excellent resistance against chlorides, pitting corrosion, and crevice corrosion. They are used in a variety of medical devices, instrumentation, chromatography, pharmaceuticals and analytical equipment where accuracy and cleanliness are critical. USA Pipings is a trusted manufacturer and supplier of Stainless Steel 316 Welded Capillary Tubes, which are bright-finished, quality tested, custom sizes and reliable exporters worldwide, products which meet ASTM A269 standards.
