ASTM A312 TP316L Stainless Steel Seamless Pipe for Petrochemical Industries

ASTM A312 TP316L Stainless Steel Seamless Pipe for Petrochemical Industries

ASTM A312 TP316L is a specification that covers seamless and welded austenitic stainless steel pipes for high-temperature and general corrosive service. TP316L is a low-carbon version of Type 316 stainless steel, offering excellent corrosion resistance and superior performance in various environments.

Key Features:

• Material Composition:

  • Chromium (Cr): 16-18%
  • Nickel (Ni): 10-14%
  • Molybdenum (Mo): 2-3%
  • Low carbon content (<0.03%) to reduce carbide precipitation and improve weldability.

• Corrosion Resistance:

  • Excellent resistance to pitting and crevice corrosion due to the addition of molybdenum.
  • Suitable for use in chloride and acidic environments.

• Mechanical Properties:

  • Tensile Strength: Minimum 485 MPa (70 ksi)
  • Yield Strength: Minimum 170 MPa (25 ksi)
  • Elongation: Minimum 35%
  • High ductility and toughness even at cryogenic temperatures.

• Standards and Specifications:

  • Manufactured to ASTM A312 standards.
  • Covers seamless, straight-seam welded, and heavily cold-worked welded stainless steel pipes.

• Applications:

  • Widely used in chemical processing, petrochemical industries, and marine environments.
  • Ideal for heat exchangers, condensers, pressure vessels, and pipelines.
  • Suitable for pharmaceutical and food processing industries due to its high corrosion resistance and sanitary properties.

• Advantages of Seamless Construction:

  • Uniform strength across the pipe with no welded seams.
  • Better pressure handling capabilities compared to welded pipes.

Benefits of TP316L:

• Low Carbon Content: Reduces the risk of intergranular corrosion after welding.
• Enhanced Durability: Superior resistance to stress corrosion cracking.
• Versatility: Suitable for both high-temperature and cryogenic applications.

Dimensions and Tolerances:

Available in a wide range of sizes, from small-diameter pipes to larger ones, with controlled tolerances on wall thickness, outside diameter, and length.
