Manufacturer′s Direct Selling Black Square Steel Pipe Seamless Metal Carbon Square Steel Pipe/Rectangular Pipe
Introduce

Seamless square rectangular steel pipe is a type of square, rectangular steel with a hollow cross-section and no seams around it. Seamless steel pipes are made from steel ingots or solid billets 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 for conveying fluids in pipelines. Compared with solid steel materials such as round steel, steel pipes have a lighter weight when their bending and torsional strength are the same. They are an economic cross-section steel and are widely used in the manufacturing of structural components and mechanical components such as petroleum drill pipes, automotive transmission shafts, bicycle frames, and steel scaffolding used in construction.

Application

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
