Comparison of hardness between square tubes and round tubes

Hollow steel pipes can be divided into square pipes and round pipes according to their shapes. The main difference between square pipes and round pipes is their shape and use. In comparison, square pipes are stronger. However, in some special fields, such as when transporting fluids, circular pipes have higher transport efficiency and better transport effects. The appropriate steel pipe should be selected according to the application requirements. Let’s take a look at the differences between round tubes and square tubes.

What is the difference between round tubes and square tubes?

Square pipes are square pipes. They and round pipes are commonly used construction steel pipes, and both are hollow steel pipes. However, there are certain differences between the two:

1. Different shapes

Square tubes are square and round tubes are round.

2. Different uses

The uses of square tubes include construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation brackets, steel structure engineering, power engineering, factories, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings, House construction, excitation vessels, oil storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher load welded structural parts, etc.

Round pipes are mainly used as pipeline pipes for conveying low-pressure fluids such as water, gas, and oil. In addition, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and as oil heaters and condensators for chemical coking equipment. Pipes for coolers, coal distillate wash oil exchangers, pipes for trestle pipe piles, and support frames for mine tunnels, etc.

Which is stronger, square tube or round tube?

Compared with square tubes and circular tubes, which one is stronger mainly depends on which one has a larger resistance moment. Generally, when the cross-sectional area is the same, the resistance moment of a square tube is larger than that of a circular tube, that is, it is stronger. In practice, During use, if it is tensile or compressive resistance, there is actually not much difference between the two steel pipes. However, if it is bending resistance, square pipes are better than round pipes.

Of course, the above is a conclusion based purely on the degree of solidity. In actual selection, square pipes are not necessarily better. For example, when transporting fluids, under the condition that the circumferences are equal, the circle area is larger than the square area and can transport more fluid. There is a large amount of fluid and the force is relatively uniform. At this time, it is obviously better to use circular tubes than square tubes.

To sum up, both types of steel pipes have their own advantages. When choosing, you must choose the appropriate steel pipe according to your needs and consider the strength of the steel pipe.
