Carbon Steel Pipe – 420 mm OD × 45 mm WT × 12 m, ASTM Grade

This carbon steel pipe is engineered for demanding industrial applications requiring robust pressure containment and high mechanical performance. With an outer diameter of 420 mm, wall thickness of 45 mm, and a standard length of 12 meters, the pipe delivers optimal strength-to-weight ratio. The calculated inner diameter is approximately 330 mm, making it suitable for significant flow volumes. Available in seamless or welded construction, it meets ASTM A106 Grade B or ASTM A53 Grade B material specifications. Designed for use in oil and gas transmission, power plant systems, steam lines, and structural applications, this pipe supports temperatures and pressures consistent with heavy-duty process systems. Its mechanical properties include high tensile and yield strength, good elongation, and hardness under 187 HB. The surface is supplied bare, with various end finish options including plain, beveled, or grooved ends to suit welding, flanging, or mechanical joints.
