ASTM A269 TP316L BA Stainless Steel Seamless Tube For Food Plant, 320# Outside Polished
ASTM A269 TP316L Bright Annealed Tube is a high-precision, corrosion-resistant austenitic stainless steel seamless tube, specifically designed for demanding industrial fluid transfer applications, food processing industry, pharmacy, etc.. The TP316L material grade is a low-carbon variant of 316 stainless steel, containing Molybdenum (2-3%), which provides superior corrosion resistance, particularly against chlorides and acids. The low carbon content minimizes sensitization during welding or annealing, ensuring excellent weldability and intergranular corrosion resistance. YUHONG GROUP is professional in producing stainless steel tubes for almost 40 years. Our tubes have been exported to more than 80 countries, such as UAE, Korea, Thailand, Saudi Arabia, Turkey, Egypt, South America, Indonesia, Italy, United Kingdom, and so on.
Different Surface Finishes (Grit Polishing):
The "#" refers to the grit size of the abrasive used in final polishing. A higher number indicates a finer, smoother finish.
180# Polish: A "satin" or "brushed" finish. Visible, uniform polishing lines. Good for general corrosion resistance and moderate cleanability.
240# Polish: A finer satin finish, with less visible lines. Offers a balance between cost and performance.
320# Polish (As Specified): A fine, smooth, semi-reflective finish. Nearly indistinguishable polishing lines. Excellent for applications requiring high cleanliness, reduced friction, and easy decontamination. Often the minimum standard for pharmaceutical and high-purity fluid systems.
400# & 600# Polish: Very smooth, highly reflective, near-mirror finishes. Used for ultra-high purity, semiconductor, and cosmetic applications where absolute minimal bacterial adhesion and particle shedding are critical.
Bright Annealed (BA) Only: The inherent shiny finish from the annealing furnace, without subsequent mechanical polishing. Smooth and clean but may have minor furnace streaks. Offers excellent corrosion resistance as the surface layer is undisturbed.
Key Features:
Excellent Corrosion Resistance: Outstanding performance in a wide range of chemical and chloride-containing environments.
High Strength & Pressure Integrity: Seamless construction offers excellent hoop strength for fluid pressure.
Hygienic & Cleanable: The 320# BA surface meets stringent sanitary requirements.
Good Formability & Weldability: 316L is readily welded using all standard techniques without post-weld annealing in most cases.
Smooth ID Surface: The bright annealing process also results in a smooth, clean internal bore, minimizing pressure drop and fluid turbulence.
Applications:
Pharmaceutical & Bioprocessing: Purified Water, Water for Injection, process piping, fermenter lines, clean steam.
Food & Beverage: Process lines for dairy, beer, juice, and high-acid foods; CIP systems.
Chemical & Petrochemical: Transfer lines for mild acids, solvents, and corrosive chemicals.
Semiconductor & High-Purity: Ultra-pure gas and chemical delivery systems.
Marine & Offshore: Instrumentation lines, hydraulic lines in salty environments.
General Industrial: Hydraulic and pneumatic lines, instrumentation tubing, heat exchanger tubes where corrosion resistance is paramount.
