From the heart of Kinshasa, Yoane Steel stands as a leading manufacturer and supplier, dedicated to supporting the robust infrastructure growth across Congo and beyond. We take pride in producing reliable API 5L Grade B PSL1 pipes, foundational components built to meet the demanding requirements of modern projects. Our commitment lies not just in supplying materials, but in delivering integrity and strength, ensuring that every length of pipe contributes to the safe and efficient development of vital energy and industrial systems.
The composition of API 5L Grade B PSL1 pipe is carefully balanced, primarily consisting of carbon, manganese, and other elements to create a strong yet workable steel. This specific recipe allows the pipe to reach key mechanical properties, including a minimum yield strength of 35,000 psi, which is its ability to resist permanent deformation. It also possesses excellent tensile strength, ensuring it can handle significant internal pressures, making it a dependable choice for a wide array of structural and transport applications.
