) Song Dynasty Seamless Steel Pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water and some solid materials. Compared with solid steel materials such as round steel, steel pipes are lighter in weight when subjected to the same bending and torsional strength. They are an economical cross-section steel and are widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, and bicycles. Frames and steel scaffolding used in construction, etc.
' )
) Song Dynasty uses steel pipes to manufacture ring-shaped parts, which can improve material utilization, simplify the manufacturing process, and save materials and processing time, such as rolling bearing rings and jacks. Sleeves, etc., are now widely manufactured with steel pipes. Steel pipes are also an indispensable material for various conventional weapons. Pipes, barrels, etc. are all made of steel pipes. Steel pipes can be divided into round pipes and special-shaped pipes according to different cross-sectional area shapes. Since the circle area is the largest when the circumferences are equal, more fluid can be transported with circular tubes. In addition, the circular cross section is relatively uniformly stressed when subjected to internal or external radial pressure. Therefore, the vast majority of steel pipes are round pipes.
' )
) Song Dynasty However, round tubes also have certain limitations. For example, when subjected to plane bending, round tubes are not as strong as square and rectangular tubes in bending strength. Some agricultural machinery frames, steel Square and rectangular tubes are commonly used in wooden furniture. Special-shaped steel pipes with other cross-sectional shapes are also required according to different uses.
