Forged to meet rigorous international standards, this pipe is engineered for durability and performance, providing our clients with the confidence that comes from using materials built to last in demanding New Zealand conditions, from major infrastructure to essential energy transport.
The composition of API 5L Grade B PSL 2 pipe is carefully balanced, primarily featuring carbon manganese steel with controlled levels of elements like phosphorus and sulphur to ensure superior weldability and toughness. Mechanically, it is defined by its reliable strength, offering a minimum yield strength of 245 MPa and a tensile strength ranging from 415 to 655 MPa. This specific combination of chemistry and mechanical properties, verified through stringent testing, guarantees a product that can handle substantial pressure and stress, making it a fundamentally sound choice for critical transmission systems.
