What are the best Stainless Steel Capillary Tube – ASTM A312 A269

Tight tolerances and a mirror-like finish are hallmarks of the best stainless steel capillary tubes. Manufactured from top-notch material, these specialized tubes are perfect for use in medical, pharmaceutical and food settings. Deeply polished inner surfaces ensure optimal performance when put in action.

For productive and reliable welding results as well as good corrosion resistance, stainless steel capillary tubes crafted from 304, 304L, 316, and 316L austenitic stainless steel grades are superior choices. To attach these tubes together, either tungsten inert gas (TIG) or plasma welding techniques may be employed.

Manufacturers strive to ensure their stainless steel capillary tubes have some key attributes. Firstly, the bore should be completely smooth and the weld bead should line up evenly with the interior of the tube. Secondly, the product is put through an annealing process to relieve any stress or strain that may have developed. Lastly, these tubes possess an incredibly high level of dimensional accuracy and a silky smooth external appearance.

Perfect for medical tools, scientific equipment, chromatography, and pressurized gas cylinders, stainless steel capillary tubes are acclaimed for their performance.
