ASTM A269 TP316L Seamless Instrument Tubing Supplier
GNEE is a renowned manufacturer, exporter, distributor, stockist, and supplier of stainless steel bright annealed tubes. Our products comply with national and international raw material quality standards.
ASTM A269 TP316L seamless bright annealed instrument tubes we supply are high-precision seamless pipes made from low-carbon stainless steel (C≤0.03%) of the American-standard TP316L grade. Processed through cold drawing and bright annealing (BA) techniques, these tubes feature smooth inner and outer walls and exhibit excellent corrosion resistance, making them particularly suitable for fields with stringent cleanliness requirements, such as high-purity gases, medical devices, and electronic instruments.
TP316L seamless bright annealed tubes comply with standards including ASTM A269 and ASME SA-312. Common specifications include outer diameters of 1/8''–4'' (metric 3–219 mm) and wall thicknesses of 0.035''–0.2'' (metric 0.5–5 mm), with inner wall roughness as fine as Ra≤0.05μm. These tubes are widely used in industries such as chemicals, semiconductors, and food and beverages for transporting corrosive media or high-purity fluids.
