01Product Overview & Specifications
API 5L PSL2 X65 (also designated L450N) is a high-strength carbon steel line pipe tailored for high-pressure, long-distance oil and gas transmission systems. As one of the high-grade X-series pipeline steels under the API 5L 44th edition specification, X65 features a minimum yield strength of 65 Ksi (450 MPa), far exceeding conventional low-grade pipeline steel.
Complying with strict PSL2 manufacturing and testing standards, API 5L X65 PSL2 pipe delivers superior tensile strength, excellent low-temperature toughness and stable weldability. It is the preferred material for onshore and offshore high-pressure trunk pipelines, deep-well transmission pipelines and heavy-duty petrochemical pipeline projects. We supply full-size seamless and welded X65 PSL2 pipes with complete certification and customized processing services for global energy pipeline engineering.

Acceptable delivery conditions for API 5L PSL2 X65 line pipes (designated by suffix letter):
R — As-rolled, normalizing rolled or normalized formed
N — Normalized, or normalized formed, or normalized and tempered
Q — Quenched and tempered
M — Thermomechanical rolled, or thermomechanical formed
Note: X65N (L450N) denotes the normalized / normalized formed delivery condition — the data in sections 03 and 04 below apply to X65N. Multiple delivery states are available to meet the stringent performance requirements of high-pressure pipeline engineering and complex service environments.
