Seamless steel pipe

Seamless steel tubes feature hollow cross-sections and are extensively used as pipelines for conveying fluids, such as oil, gas, water, and certain solid materials. Compared to solid steel like round bars, they have the same bending and torsional strength but are lighter in weight, making them an economical section steel. They are widely employed in the manufacturing of structural components and mechanical parts, such as oil drilling pipes, automotive drive shafts, bicycle frames, and steel scaffolding for construction. Manufacturing ring-shaped parts from steel tubes enhances material utilization, simplifies production processes, and saves materials and labor, and has become a common practice.
