A round pipe is a tubular material with a circular cross-section. It is commonly used for transporting liquids, gases and steam, as well as serving as structural support components. Manufactured in various materials, specifications and processes, round pipes are widely applied in construction, machinery, petroleum, chemical and other industries. The surface can be treated by galvanizing, coating, polishing and other methods to enhance corrosion resistance and appearance.
