Marzouk Steel, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality steel products for the energy and infrastructure sectors. One of its proven pipeline solutions is Carbon Steel API 5L X42 PSL 2 Pipes, designed for safe and reliable transportation of oil, gas, and water. Manufactured in accordance with API 5L specifications, PSL 2 pipes offer enhanced chemical control, mechanical properties, and impact testing requirements. Marzouk Steel ensures strict quality assurance and traceability, delivering X42 PSL 2 pipes that meet international standards and perform reliably in demanding pipeline environments.
API 5L X42 PSL 2 Pipes are produced from high-quality carbon steel with controlled chemical composition, including carbon, manganese, phosphorus, sulfur, and micro-alloying elements. PSL 2 requirements ensure improved toughness, higher yield strength, and stricter limits on impurities. These pipes provide excellent tensile strength, good ductility, and strong resistance to internal pressure and mechanical stress. Impact testing and notch toughness requirements enhance safety and performance in both onshore and offshore pipeline applications.
