Hot Rolled Grade B Carbon Steel Seamless Pipe
Product introduction
Hot Rolled Grade B Carbon Steel Seamless Pipe offers exceptional advantages through its seamless, one-piece construction, which eliminates weld seams and provides a 15%-20% higher burst resistance compared to welded pipes. The hot rolling process refines the internal metal grain structure, ensuring uniform wall thickness and outstanding mechanical properties, including a minimum yield strength of 240 MPa and tensile strength of 415 MPa. This guarantees reliable performance under extreme high temperatures (up to 450°C) and high pressures, while its optimized chemical composition ensures excellent weldability and formability for complex installations. Furthermore, its robust structure provides superior fatigue resistance and corrosion durability, significantly extending the pipeline's service life and reducing long-term maintenance costs in critical oil, gas, and power generation applications.
Product feature and application
Hot Rolled Grade B Carbon Steel Seamless Pipe is engineered for high-temperature and high-pressure fluid transport, featuring a seamless structure that eliminates weld seams and enhances burst resistance by 15%-20% compared to welded alternatives. Its hot-rolled manufacturing process ensures uniform wall thickness, superior mechanical properties (minimum yield strength of 240 MPa, tensile strength ≥415 MPa), and excellent weldability, making it ideal for demanding applications in oil & gas, petrochemical, power generation, and industrial piping systems where reliability under extreme conditions is critical.
Production details
