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.

1. Purpose of Cold Drawn Seamless Rectangular Pipe Cold drawn seamless rectangular pipe is widely used in construction, machinery, chemical, light industry, automotive, aerospace, metallurgy, and other industries, and can be made into pipes of various sizes, shapes, and performance.
2. Seamless cold drawn square pipe is a kind of hollow square section lightweight thin-walled steel pipe, also known as steel cold formed profiles. Seamless cold drawn square tubes are widely used. It is widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction. Steel pipes are widely used to manufacture circular parts, which can improve material utilization, simplify manufacturing processes, and save materials and processing hours. Steel pipes have been widely used for manufacturing.
