Seamless steel tube

Seamless steel tubes feature a hollow cross-section 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 are lighter in weight while maintaining the same bending and torsional strength. As an economical cross-section steel, they are widely employed in the production of structural components and mechanical parts, including oil drilling pipes, automotive drive shafts, bicycle frames, and steel scaffolding for construction. Manufacturing circular components from steel tubes enhances material utilization, simplifies production processes, and saves materials and labor, making them a popular choice for manufacturing.
