API 5L grade X65 PSL 1 / PSL 2 carbon steel seamless line pipes & tubes

API 5L X65 is a common carbon steel pipeline material, which can be divided into two grades: PSL 1 and PSL 2. These pipelines are widely used in the field of oil and gas transportation, with high strength and good welding performance.

PSL Level 1 has lower requirements and is suitable for general applications, requiring strict control of chemical composition. PSL Level 2 includes stricter requirements for chemical composition, mechanical properties, and smelting processes, making it suitable for more demanding working conditions.

The API 5L X65 pipeline has excellent pressure resistance and corrosion resistance, and performs well in liquid and gas transmission. Its design complies with API standards, ensuring the reliability and safety of pipelines in various environments, and is therefore widely used in the oil and gas industry to meet long-distance transportation needs.
