Description

ASTM A 269-02a Stainless Steel Pipe is the standard specification for stainless steel pipe for systems requiring corrosion resistance and high strength. This standard applies to seamless or welded stainless steel pipes used in applications such as conveying liquids, gases, and solids at high pressures and in harsh environments.

Applications

  • Chemical industry: Used in corrosive chemical transmission systems.
  • Oil and gas industry: Used in oil and gas pipeline systems.
  • Food and beverage industry: Used in food and beverage production and transportation systems.
  • Medical Industry: Used in medical equipment and medical gas piping systems.
  • Energy industry: Used in power plants and renewable energy systems.

Standards

ASTM A 269-02a covers many different grades of stainless steel, including but not limited to:

  • Austenitic Stainless Steel: Common types include 304, 304L, 316, 316L.
  • Ferritic Stainless Steel: Types such as 430, 444.
  • Duplex Stainless Steel: Types such as 2205, 2507.
