What is the general thickness of the rectangular tube commonly used in engineering?
Rectangular tube is a common metal material that is widely used in the engineering field. The advantages of rectangular tubes include high strength, light weight, corrosion resistance, and ease of processing, making them ideal for many engineering projects. In engineering practice, the thickness of the rectangular tube is a very important parameter, which is directly related to the bearing capacity and service life of the rectangular tube. So, what is the general thickness of the rectangular tube commonly used in engineering?This article will introduce you to it.
According to the provisions of the national standard GB T 3094-2012 "Cold-drawn special-shaped steel pipe", the wall thickness of rectangular pipe can vary according to the diameter and material. In general, the wall thickness of a rectangular tube should not be less than 1 20 of its diameter and should not be greater than 1 10 of its diameter. For rectangular tubes made of Q235, the wall thickness should not be less than 15mm；For the rectangular tube made of Q345, its wall thickness should not be less than 20mm。
In practical applications, the thickness of rectangular tubes is also affected by many other factors. For example, in the case of high loads or high strength, the thickness of rectangular tubes increases accordingly. In addition, some special-purpose rectangular tubes may require higher corrosion or fire resistance, and their thickness will be increased accordingly.
In general, the wall thickness of the rectangular pipe commonly used in engineering is generally 15mm to 20mm, but the specific thickness still needs to be determined according to the actual application. When selecting a rectangular tube, it should be considered comprehensively according to the actual needs and relevant standards to ensure that the selected materials can meet the specific requirements of the project.
