ERW Welded Steel Pipe DN508 ASTM A53 GR.B SCH80 For Industrial Process Piping

Huayang DN508 ASTM A53 Gr.B SCH80 ERW welded steel pipes are manufactured using advanced high-frequency electric resistance welding technology, delivering uniform wall thickness, precise dimensional tolerances, and high-quality weld seams. ASTM A53 Grade B offers a minimum yield strength of 240 MPa and a minimum tensile strength of 415 MPa, providing excellent weldability, ductility, and structural reliability. The SCH80 wall schedule increases pressure capacity and mechanical durability, making the pipe suitable for process piping, steam distribution, compressed air systems, cooling water circuits, and refinery utilities. Every pipe undergoes hydrostatic pressure testing, ultrasonic weld inspection, eddy current examination, and dimensional verification to ensure compliance with ASTM requirements and reliable long-term operation in industrial process environments.
