Seamless Square Pipe

Seamless square pipes are long steel bars with hollow cross-sections and no seams around the perimeter. Inside, they are hollow with a specified cross-sectional area, and are extensively used as pipelines for conveying fluids, such as oil, natural gas, coal gas, water, and certain solid materials. They are widely employed in the manufacture of structural components and mechanical parts, including oil drilling rods, automotive drive shafts, bicycle frames, and steel scaffolding used in construction.
