Theoretical weight calculation formula for steel square tubes

Formula for calculating the theoretical weight of square tubes:

(b-t)×4×ρ×t×C/1000000=kg

Explanation of formula for calculating the theoretical weight of square tubes

b: Side length of square tube (unit: mm)
t: The wall thickness of the square tube, also called the thickness of the steel plate (unit: mm)
ρ: Density of steel (the density of ordinary steel and manganese plates is generally 7.85. For stainless steel or other materials, please refer to the material density table)
C: The height of the square tube/or the length of the square tube (unit: mm). Generally, the weight of the square tube is calculated in units of 1 meter.

Note: The length, width, and height units are all in millimeters for the purpose of unifying the units so that calculations are less likely to go wrong, so in the end you have to divide by 1,000,000 to get the weight unit in kilograms.

The formula for calculating the weight of rectangular tubes is: 2×channel (side length 1+side length 2-wall thickness)×wall thickness×board length×density kg/m.
The calculation formula for the weight of round pipes is: (pipe diameter - wall thickness) × wall thickness × 0.02466 kg/m.

Extended information:

Square tube is a square tube type. Many kinds of materials can be used to form a square tube body. It is used as a medium. What is it used for and where is it used? Most square tubes are mostly steel tubes. After unpacking and smoothing, It is curled and welded to form a round tube, which is then rolled into a square tube and then cut to the required length.

Generally, there are 50 square tubes per pack. In terms of spot, the large sizes are mostly 10*10*0.8-1.5~~500*500*10-25. Square tubes are divided into structural square tubes, decorative square tubes and construction square tubes according to their uses. , mechanical square tube, etc.

Square tubes are very common in our daily lives. They are widely used in house construction, shed construction, boiler construction, highway railings, house construction, pressure vessels, petroleum storage tanks, bridges, power station equipment, etc. It can be seen that the use of square tubes It also occupies a large position in the steel processing industry.
