ASTM A269 / ASME SA269 TP316L Polished Austenitic Stainless Steel Welded Tube

ASTM A269 specifies the requirements for seamless and welded austenitic stainless steel 304/ 304L/ 316L/ ... / 317/ 321/ 347 tubing intended for general corrosive service, which commonly used in piping and plumbing applications.

Tube Manufacturing & Process:

  • Welded Construction: Formed from flat-rolled stainless steel strip/sheet, longitudinally welded (TIG, laser, or plasma welding).

  • Polished Finish: Surface is mechanically polished (e.g., #4 brushed, mirror, or electropolished) to improve:

    • Hygiene: Reduces bacterial adhesion (critical for food, pharma, and medical applications).

    • Aesthetics: Smooth, reflective appearance.

    • Corrosion Resistance: Minimizes surface defects that could trap contaminants.

Comparison with Other Standards

1. ASTM A312
Purpose: Similar to ASTM A269, ASTM A312 covers both seamless and welded austenitic stainless steel pipes but is specifically intended for high-pressure applications.
Grades: Includes similar grades as A269 but also specifies additional requirements for pressure applications.
Usage: A312 is generally used in situations requiring higher mechanical strength and pressure ratings.
2. ASTM A511
Purpose: While ASTM A269 is primarily for tubing in various services, ASTM A511 is focused on seamless stainless steel tubing for mechanical applications.
Differences: A511 typically includes stricter mechanical properties and dimensions since it's intended for specific mechanical applications.
3. ASTM A554
Purpose: This specification is for welded stainless steel tubing intended for mechanical and structural applications, with a strong emphasis on aesthetic appearance.
Grades: Generally covers lower grades of stainless steel than those in A269 and is often used in decorative applications like railings and furniture.
4. ASTM A249
Purpose: Focused on stainless steel tubing for heat exchangers, condenser, and similar applications.
Standards: A249 places more emphasis on mechanical properties, weld performance, and achieving a suitable surface finish for heat transfer applications.


Applications

  • Pharmaceutical/Biotech: Clean-in-place (CIP) systems, process piping.

  • Food & Beverage: Sanitary tubing, dairy processing.

  • Chemical Processing: Acid/caustic fluid transfer.

  • Marine/Coastal: Saltwater-exposed components.

  • Medical Devices: Implants, surgical instruments (post-processing may be required).
