Luke Steel provides high-quality Carbon Steel API 5L X52 PSL2 Pipes from its plant in Houston, produced specifically to meet medium-pressure applications of the oil, gas, and petrochemical industries. API 5L X52 PSL2 pipes provide higher mechanical properties and stringent quality control compared to their PSL1 equivalent. With enhanced chemical composition, weldability, and toughness, these pipes are perfect for effective and secure hydrocarbon transportation. Luke Steel provides complete traceability, inspection documentation, and on-time delivery for meeting the stringent requirements of pipeline infrastructure across the globe.
API 5L X52 PSL2 pipes are constructed from carbon-manganese steel with addition of elements such as niobium and vanadium. These pipes have a minimum of 360 MPa yield strength and tensile strength of 460–760 MPa. The PSL2 specifications provide enhanced toughness, tighter chemical content, and uniform mechanical behavior at pressure. The pipes undergo hardness testing, impact test, and dimensional tolerance for ensuring performance under sour service and non-sour service.
