Based in the heart of Hamilton’s industrial sector, Latham Steel has built a strong reputation as a reliable partner for high-quality steel products. We are proud to supply API 5L Grade L290 pipe, a product engineered to meet the demanding requirements of the modern energy sector. Our commitment is to deliver materials that not only meet stringent international specifications but also provide the durability and performance our clients in New Zealand and beyond have come to trust for their most critical infrastructure projects.
The API 5L Grade L290 pipe is defined by a carefully balanced chemical composition and robust mechanical properties. It is a carbon manganese steel, often with micro-alloying elements, designed to offer a specified minimum yield strength of 290 MPa. This grade provides an excellent combination of high strength, good toughness, and reliable weldability, making it a versatile and dependable choice for constructing pipelines that must perform safely under substantial pressure over long periods.
