avantaj
Compared with solid steel such as round steel, the steel pipe is lighter in weight when the bending and torsional strength is the same. and steel scaffolding used in building construction. Making ring parts with steel pipes can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets, etc., which have been widely used in steel pipe manufacturing.

Steel pipe is also an indispensable material for various conventional weapons. Gun barrels, barrels, etc. must be made of steel pipes. Steel pipes can be divided into round pipes and special-shaped pipes according to the shape of the cross-sectional area. Since the area of the circle is the largest under the condition of equal perimeter, more fluid can be transported with a circular tube. In addition, when the ring section is subjected to internal or external radial pressure, the force is relatively uniform. Therefore, most steel pipes are round pipes. However, round pipes also have certain limitations. For example, under the condition of plane bending, round pipes are not as strong as square and rectangular pipes. Some agricultural machinery skeletons, steel and wood furniture, etc., are commonly used. Special-shaped steel pipes with other cross-sectional shapes are also required according to different purposes.
