Material Characteristics and Huayang Supply Capability
API 5L Grade B is a carbon-manganese steel with a minimum yield strength of 245 MPa and tensile strength ranging from 415 to 560 MPa, making it suitable for medium-pressure oil and gas transmission. Within the DN150–DN350 range, ERW pipes offer tight dimensional tolerance and excellent weld seam consistency. Huayang manufactures these pipes using controlled steel coils and online seam heat treatment to enhance weld toughness. Each pipe is subjected to hydrostatic testing, ultrasonic inspection, and chemical composition verification, ensuring compliance with API 5L requirements and meeting the reliability expectations of Petrobras projects.
