Applications:
Pharmaceutical and Biotechnology: Used in high-purity fluid transfer systems for its clean surface and resistance to contamination.
Chemical Processing: Suitable for handling aggressive chemicals and gases in high-precision piping systems.
Semiconductor Manufacturing: Ensures high-purity gas and fluid transfer in critical production processes.
Automotive and Aerospace: Used in fuel lines, hydraulic systems, and exhaust components requiring high strength and durability.
ASTM A269 seamless tubes are crafted from high-performance stainless steel grades such as 304, 304L, 316, 316L，2205 and 2507. These materials are selected for their exceptional corrosion resistance, mechanical strength, and ability to perform in extreme environments. The bright annealing process is applied to create a clean, polished surface that is highly resistant to oxidation and suitable for demanding applications requiring high-purity standards.
Designed for critical applications, ASTM A269 bright annealed seamless tubes deliver superior strength, dimensional accuracy, and a smooth surface finish. Their seamless construction eliminates weak points, ensuring reliability under high pressure and precision systems. The bright annealing process not only improves surface aesthetics but also enhances the tube’s resistance to contamination, making it suitable for applications where cleanliness and durability are essential.
Process of Precision tubes: Bright annealed & Polished Grit K240/320
