Filiz Steel, based in Istanbul, Turkey, has earned a solid reputation as a reliable manufacturer and supplier of top-notch carbon steel pipes, specifically designed for the demanding needs of energy and infrastructure projects. One of their standout products is the Carbon Steel API 5L X56 PSL 2 Pipe, which is produced in line with the American Petroleum Institute’s API 5L standard. These pipes are expertly crafted for the safe and efficient transport of oil, natural gas, and water, making them perfect for both offshore and onshore pipeline systems. Filiz Steel takes pride in ensuring that every pipe adheres to strict PSL 2 quality standards, covering everything from mechanical performance to chemical composition and non-destructive testing.
The Carbon Steel API 5L X56 PSL 2 Pipes are made from micro-alloyed carbon steel, featuring enhanced chemical controls compared to PSL 1. They boast impressive mechanical properties, including a minimum yield strength of 390 MPa and tensile strength that ranges from 490 to 760 MPa. The PSL 2 standard imposes more rigorous requirements for notch toughness, chemical composition (like lower carbon and sulfur levels), and additional testing, such as impact tests and non-destructive inspections. These pipes are designed for improved weldability, consistency, and reliability, making them ideal for critical applications that operate under high pressure or in extreme conditions.
