Product Description:

ASTM A213 / A269 TP316L Stainless Steel Seamless Tube Bright Annealed Tube

 

 

Bright annealed tube, also known as BA tube, is a type of steel tubing that goes through a specific annealing process to achieve a bright, polished surface finish. The purpose of the annealing process is to remove any scale, oxide, or other impurities from the surface and to improve the tube's mechanical properties.

 

 

Here are some key features and applications of bright annealed tubes:

  1. Surface finish: Bright annealed tubes have a smooth and reflective surface finish, similar to a mirror. This surface finish provides enhanced corrosion resistance and aesthetic appeal, making it suitable for various decorative and architectural applications.

  2. Material: Bright annealed tubes are typically made from stainless steel, specifically austenitic grades such as 304 and 316. These grades offer excellent corrosion resistance and are suitable for a wide range of industries, including food and beverage, pharmaceuticals, automotive, and chemical processing.

  3. Dimensional accuracy: Bright annealed tubes are manufactured with tight dimensional tolerances, ensuring precise outer diameter (OD), inner diameter (ID), and wall thickness. This accuracy is crucial in applications where tight-fitting connections or smooth flow characteristics are required.

  4. Heat treatment: The bright annealing process involves heating the stainless steel tubes to a specific temperature and holding them there for a certain period. This allows the material to recrystallize and eliminate any defects or stresses caused during the manufacturing process. It results in improved mechanical properties, such as high strength and ductility.

  5. Welding and forming: Bright annealed tubes can be easily welded using conventional methods. The heat treatment process restores the material's corrosion resistance near the weld area. Additionally, the tubes can be formed into various shapes and sizes using bending or machining techniques, making them versatile for different applications.

  6. High purity and cleanliness: The bright annealing process removes the oxide layer and scales from the tube's surface, ensuring high purity and cleanliness. This feature is crucial in applications where contamination must be minimized, such as in the pharmaceutical or semiconductor industries.

  7. Pressure and temperature resistance: Bright annealed tubes exhibit excellent pressure and temperature resistance, making them suitable for high-pressure and high-temperature applications. Their corrosion resistance allows them to withstand aggressive environments, including chemical exposure and saltwater applications.
