ASFLOW is one of the leading manufacturers of ultra high purity fittings and tubing for the semiconductor, aerospace and pharmaceutical industries. To meet the high demands of industry, Asflow uses only 316 or 316L VIM/VAR stainless steel. Cutting-edge fittings and tubing eliminate the need for material outgassing and purification while improving corrosion resistance when using exotic gases and chemicals. All fittings and tubing are available in imperial and metric sizes and with an electropolished surface finish of Ra. 0,13µm (5µin) or Ra. 0,25 µm (10 µin).
FITOK stainless steel weld fittings are manufactured and tested according to ANSI standard B16.11. The standard material for weld fittings is stainless steel 316 SS. Barstock items are manufactured according to ASME SA479, ASTM A276, forged items according to ASME SA182, ASTM A182. This ensures an excellent weldability to other tube and piping components available.
