Technical QA/QC Verification
• 100% Traceable Mill Certificates: Every delivery includes comprehensive EN 10204 3.1 Mill Test Certificates (MTC) presenting specific heat chemistry data, Hydrostatic testing pressure results, Charpy V-Notch impact test values, and Elcometer coating profiles. Fully ready for third-party validation by SGS, Bureau Veritas, or Intertek.
• Financial Security Guarantee: We mitigate international procurement risk completely by managing major infrastructure manufacturing supply contracts via 100% Irrevocable Letters of Credit (L/C) at sight.
Anti-Rust Packaging & Ocean Logistics
• Industrial Heavy-Load Structural Boxing: Beveled pipe ends are fitted with heavy-duty plastic or metallic protectors to eliminate face deformity during handling. Bundles are secured with dry high-load metallic strapping, anti-chafing separation slings, and heavy wood blocking built for extreme maritime stability.
• Extended Free Port Demurrage: SXY Steel Group arranges 14 to 21 days of complimentary container or breakbulk demurrage at your destination terminal to secure your domestic haulage setup and local custom clearances.
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 (80,500 psi) Yield Strength (Max): 705 MPa (102,300 psi) Tensile Strength (Min): 625 MPa (90,600 psi) |
| Weld seam of EW, LW, SAW and COW pipe | Tensile Strength (Min): 625 MPa (90,600 psi) Tensile Strength (Max): 825 MPa (119,700 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). |
X80 Pipe yield strength

Packing and shipping
Our company has passed ISO9001 quality management system certification, Our Mill product with CE/EN10204 / ASTM/Classification society certificate/CASO/BIS etc certificate.All the customers give good appreciation to our products.We are glad to be your good partner.

Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.

Factory workshop
With a commitment to excellence, innovation, and sustainability, the company has established itself as a trusted partner in the international steel industry.After nearly two decades of relentless endeavour, our client base now spans over 110 countries and regions across Europe, the Middle East, South America, and Southeast Asia.
