Do you know about round tubes?
Round tubes refer to Steel Tubes with open ends and hollow concentric cross-sections. According to the production method, they can be divided into seamless round tubes and welded round tubes.
The specifications of round tubes are expressed by the outer dimensions (such as outer diameter or side length), inner diameter and wall thickness. The size range is very wide, and users can reasonably purchase or customize the size according to processing needs.
[Common materials]: 10#, 20#, 35#, 45#, 16Mn, 27SiMn3, 27SiMn, Cr5Mo2, Q235, Q345
[Product type]: Black aging tube, bright tube, galvanized tube
[Supply type]: Spot, can be customized according to special needs and requirements

1. Shape: As the name suggests, circular pipes have a circular shape, while square pipes have a rectangular shape.
2. Section shape: The section of a circular tube is circular, while a square tube is rectangular.
3. Wall shape: The wall of a circular tube is uniform and thin, while the wall of a square tube may exhibit unevenness such as protrusions and indentations.
4. Processing difficulty: Due to the simple shape of round tubes, processing is relatively easy, while the processing difficulty of square tubes is relatively high.
Advantages of circular pipes:
(1) High strength: With a small force bearing area, it has a strong ability to withstand twisting and other forces.
(2) Good welding quality: During welding, it is easy to produce a horn shape at the interface, which is less likely to cause welding cracking.
(3) Easy plastic deformation: Round pipes are more prone to plastic deformation and are easier to form compared to square pipes.
The characteristic of a circular tube is that it can withstand both force and plastic deformation, so it is suitable for applications that require resistance to torsion and impact, such as bridges, automotive chassis, machinery and equipment; At the same time, it is widely used in pipeline transportation or building components.
The shape of the circular tube is simple and the processing is relatively easy, so the processing cost of the circular tube is relatively low.
