Product Description

Introduce

Seamless rectangular steel pipe is a square, rectangular steel pipe with a hollow section and no seams around it. Seamless steel pipes are made from steel ingots or solid tube blanks that are perforated into tubes, and then hot rolled, cold rolled, or cold drawn. Seamless steel pipes have a hollow cross-section and are widely used as pipelines for conveying fluids. Compared to solid steels such as round steel, steel pipes have a lower weight and the same flexural and torsional strength. They are a type of economical cross-section steel, and are widely used in the manufacture of structural and mechanical components such as petroleum drill pipes, automotive transmission shafts, bicycle racks, and steel scaffolds used in construction.
