ASTM A335 P11 Seamless Steel Pipe

Synergistically evolve technologies rather than just in time initiatives. Quickly deploy strategic networks with compelling e-business. Credibly pontificate highly efficient manufactured products and enabled data.

ASTM A335 P11 Seamless Steel Pipe is a standard specification for alloy steel pipes, where “P11” indicates the specific grade of the pipe. This type of pipe is suitable for high-temperature and high-pressure environments, commonly used in industries such as petroleum, chemical, power generation, and nuclear industries for transporting high-temperature and high-pressure fluids.

Main Alloying Elements:

  • Chromium (Cr): 1.00-1.50%
  • Molybdenum (Mo): 0.44-0.65%

These alloying elements provide the pipe with excellent high-temperature, corrosion-resistant, and pressure-resistant properties. Pipes of grade P11 typically exhibit high tensile and yield strength, demonstrating good stability and reliability in high-temperature environments.

Chemical Composition:

  • Carbon (C): 0.05-0.15%
  • Manganese (Mn): 0.30-0.60%
  • Silicon (Si): 0.50-1.00%
  • Phosphorus (P): Not exceeding 0.025%
  • Sulfur (S): Not exceeding 0.025%

Mechanical Properties:

  • Yield Strength: ≥ 205 MPa
  • Tensile Strength: ≥ 415 MPa
  • Elongation: ≥ 30%

Dimensions and Wall Thickness:

  • Outside Diameter Range: 1/2″ – 36″ (21.3 mm – 914 mm)
  • Wall Thickness Range: SCH 20 – SCH XXS (2.11 mm – 250 mm)

ASTM A335 P11 Seamless Steel Pipe offers excellent high-temperature, corrosion-resistant, and pressure-resistant properties, making it suitable for transporting fluids in high-temperature and high-pressure environments.
