Stainless Steel Bright Annealed Tube Process and Features:

Stainless Steel Bright Annealed Pipe employs the Bright Annealing process. During the pipes production, a high-temperature annealing is conducted using pure argon gas within the furnace atmosphere. This helps to eliminate grain deformation caused by processing and remove residual grease from the pipes surface. This process, while annealing at high temperatures, facilitates a carbon-oxygen reaction with the argon gas, further enhancing the surfaces brightness and smoothness. The Bright Annealing process yields the following characteristics:

- Stringent control of outer diameter and wall thickness tolerances

- Complete bright annealing enhances corrosion resistance on the surface

- Excellent weldability

- Rigorous cleaning and production processes result in controlled surface roughness

- Surface Finish: The BA Tube boasts a highly polished and mirror-like surface, which not only enhances its aesthetic appeal but also contributes to its resistance against corrosion and oxidation.

- Precision Tolerances: The manufacturing process ensures precise dimensional tolerances, including outer diameter, inner diameter, and wall thickness, meeting industry standards and customer requirements.

- Material Grades: The BA Tube is available in various stainless steel grades, with common options being TP316L and TP304L, ensuring compatibility with diverse applications.

- Applications: Due to its exceptional surface quality and corrosion resistance, the Stainless Steel Bright Annealed Tube finds utility in industries such as pharmaceuticals, food and beverage, electronics, and more.

- Standards: The BA Tube conforms to recognized industry standards such as ASTM A213 and ASTM A269, ensuring its reliability and quality.
