Filiz Steel, located in Istanbul, Turkey, stands out as a top manufacturer and supplier of high-performance carbon steel pipes, catering to the global oil, gas, and energy industries. Among its cutting-edge products is the Carbon Steel API 5L X65 PSL 2 Pipe, crafted in line with the American Petroleum Institute’s API 5L standard. These pipes are specifically designed for high-pressure, high-strength pipeline applications, making them perfect for transporting oil, natural gas, and water over long distances. Filiz Steel guarantees that all X65 PSL 2 pipes adhere to rigorous mechanical, chemical, and non-destructive testing standards, ensuring reliability in critical service environments.
The Carbon Steel API 5L X65 PSL 2 Pipes are made from micro-alloyed carbon steel, featuring a carefully controlled chemical composition that includes low carbon (up to ~0.26%) along with balanced amounts of manganese, phosphorus, sulfur, and other elements. They boast a minimum yield strength of 450 MPa and a tensile strength ranging from 535 to 760 MPa. As a PSL 2 grade, these pipes are held to more stringent standards than PSL 1, which includes notch toughness testing, tighter limits on chemical composition, and mandatory nondestructive testing. These characteristics ensure excellent weldability, impact resistance, and durability even in challenging conditions.
