The seamless steel pipe is a circular, square, rectangular steel with a hollow section and no seams around it. The seamless steel pipe is formed by perforating a steel ingot or a solid tube blank, and then hot rolled, cold rolled or cold drawn. Seamless steel tubes have a hollow cross-section and are used in a large number as pipes for conveying fluids. Compared with solid steels such as round steel, steel pipes have a lighter weight when subjected to the same torsional strength, and are economical cross-section steels. They are widely used in manufacturing structures. Parts and mechanical parts such as oil drill pipes, automobile drive shafts, bicycle racks, and steel scaffolding used in construction.
