API 5L X80 carbon welded steel pipe

API 5L X80 Pipe is a specification for steel line pipe used in pipeline transportation systems for oil, gas, and water. API 5L X80 grade steel is designed for high-pressure applications and is used in demanding environments, including arctic regions, where high strength and excellent low-temperature toughness are required.

Technical data

ASTM API 5L X80 Seamless and Welding Steel Tube Mechanical Properties:

Grade	API 5L X80 / PSL2 (for both pipe body and weld seam of applicable pipe types)
Pipe body of seamless and welded pipes	Yield Strength (Min): 555 MPa(500 psi) Yield Strength (Max): 705 MPa(300 psi) Tensile Strength (Min): 625 MPa(600 psi)
Weld seam of EW, LW, SAW and COW pipe	Tensile Strength (Min): 625 MPa(600 psi) Tensile Strength (Max): 825 MPa(700 psi) Note: "COW" is not a standard welding process designation for API 5L line pipe. The common types are ERW, HFW, SAW (Longitudinal or Spiral).
X80 Pipe yield strength	Yield Strength (Min): 555 MPa Tensile Strength Range: 625 - 700 MPa (Typical specified range for pipe body, may vary slightly by standard edition and supplemental requirement) Elongation (Min): 20% (Typical minimum, dependent on specimen size per API 5L) Yield-to-Tensile Ratio (Max): ≤ 0.93 (Typical requirement for high-grade line pipe to ensure strain capacity, please refer to the latest API 5L specification for the exact value).
