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 products like round bars, seamless steel tubes offer 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. The production of annular components using seamless steel tubes enhances material utilization, simplifies manufacturing processes, and saves materials and processing time, and is thus widely used.
