Custom X60 seamless steel pipe pipeline API Spec 5L

The customization of API 5L X60 seamless steel pipe must comply with PSL2 standard, with a yield strength of ≥ 415MPa and a C-Mn composition design (C ≤ 0.26%, Mn ≤ 1.40%). The typical specifications are an outer diameter of 34-762mm and a wall thickness of 3-120mm. It is produced through hot rolling process and undergoes a -20 ℃ low-temperature impact test (≥ 40J).

When customizing, it is necessary to specify the heat treatment status (hot rolling/normalizing), PSL2 level requires stricter dimensional tolerances (± 0.75% for outer diameter ≥ 60mm), and ultrasonic testing of the entire X60 pipe body. API Spec 5L 60 seamless steel pipe is suitable for oil, natural gas transportation, and chemical equipment.
