Compared with square pipes and round pipes, which one is stronger mainly depends on which one has a larger resistance moment. Generally, under the same cross-sectional area, square pipes have a larger resistance moment than circular pipes, that is, they are stronger. In practice In the process of use, if it is tensile or compressive, there is actually no big difference between the two steel pipes, but if it is bending resistant, square pipes are better than round pipes
Of course, the above is a conclusion based solely on the degree of firmness. In actual selection, square pipes are not necessarily better. For example, when transporting fluids, under the condition of equal circumference, the circle area is larger than the square area, which can transport more pipes. There is a lot of fluid, and the force is relatively uniform. At this time, it is obviously better to use a round pipe than a square pipe. In summary, the two steel pipes have their own advantages. When choosing, you must choose the appropriate steel pipe according to your needs. And consider the firmness of the steel pipe.
