Square tubes and rectangular tubes are two common metal products, and they have a wide range of applications in construction, machinery, automobiles, and other fields. This article will introduce the definition, classification, and application of square and rectangular tubes.
First, the square tube. A square tube is a steel tube with a square cross-section, with four sides of equal length and a square cross-section. Square tubes are usually made of high-quality steel, which has high strength and stiffness, and is able to withstand large pressure and bending forces.
The classification of square pipes is mainly as follows:
1.Classification by material: square pipes can be divided into carbon steel square pipes, stainless steel square pipes, alloy steel square pipes, etc.
2.Classification according to wall thickness: the wall thickness of the square tube can be adjusted according to the need, and the commonly used wall thickness is 1mm, 12mm、1.5mm, 2mm, etc.
3.Classification according to specifications: The specifications of square tubes are usually expressed by side length, and the commonly used specifications are 50mm 50mm, 75mm 75mm, 100mm 100mm, etc.
Square tubes are widely used in the following fields:
1.Construction: Square tubes can be used in the supporting structure and frame structure of the building to improve the stability and safety of the building.
2.Mechanical field: square tubes can be used in the manufacture of mechanical equipment, such as machine tools, cranes, etc., to improve the strength and rigidity of equipment.
3.Automotive: square tubes can be used in the manufacture of automobile bodies, improve the strength and rigidity of the body, and ensure the safety and stability of the vehicle.
2. Rectangular tube.
A rectangular tube is a kind of steel pipe with a square section and a rectangular section, in which the four sides are long, the opposite two sides are equal in length, and the other two sides are also equal in length, and the cross-section is square or rectangular. Rectangular tubes are usually made of high-quality steel, which has high strength and rigidity, and can withstand large pressure and bending forces.
The classification of rectangular tubes is mainly as follows:
1.Classification by material: rectangular pipes can be divided into carbon steel rectangular pipes, stainless steel rectangular pipes, alloy steel rectangular pipes, etc.
2.Classification according to wall thickness: the wall thickness of rectangular tube can be adjusted according to needs, and the commonly used wall thickness is 1mm, 12mm、1.5mm, 2mm, etc.
3.Classification according to specifications: The specifications of rectangular tubes are usually expressed by side length, and the commonly used specifications are 50mm 50mm 5mm, 75mm 75mm 6mm, 100mm 100mm 8mm, etc.
The application of rectangular tube is also very wide, mainly used in the following fields:
1.Construction: Rectangular tubes can be used in the supporting structure and frame structure of buildings to improve the stability and safety of buildings.
2.Mechanical field: rectangular tubes can be used in the manufacture of mechanical equipment, such as machine tools, cranes, etc., to improve the strength and rigidity of equipment.
3.Automotive: rectangular tubes can be used in the manufacture of automobile bodies, improve the strength and rigidity of the body, and ensure the safety and stability of the vehicle.
4.Shipyard: rectangular tubes can be used in the manufacture of ships, improve the strength and rigidity of ships, and ensure the safety and stability of ships.
5.Petrochemical field: rectangular tubes can be used in the manufacture of petrochemical equipment, such as reactors, towers, etc., to improve the strength and rigidity of the equipment.
In a word, square tubes and rectangular tubes are two common metal products, and they have a wide range of applications in construction, machinery, automobiles, and other fields. With the continuous development and progress of science and technology, the manufacturing technology of square tubes and rectangular tubes will also be continuously improved and perfected to provide better support and guarantee for the development of all walks of life.
