Weight calculation of A500 rectangular tube

Posted by chase Liu on April 20th, 2023

A500 rectangular tube is a hollow long strip of steel, also known as flat tube, flat square tube or square flat tube. It is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures and the production of various conventional weapons, barrels, shells, etc.

A500 rectangular tube is a common variety in pipes. Its weight calculation formula is:

Weight=density×volume=density×(cross-sectional area×length), namely: m=ρ×V=ρ×(F×L)

To adjust the weight, the most important thing is to calculate the size of the cross-sectional area.

The cross-sectional shapes of square tubes and rectangular tubes are divided into two types: rounded corners and right angles. In the specific adjustment, the R angle of the rounded pipe is usually ignored.

Look at the calculation formula carefully, and with a little imagination, you can know that this is calculated by cutting and flattening the cross-sectional square rectangular ring into a slender rectangle. In fact, other profiles, such as I-beams, H-beams, etc., can also be easily adjusted with this idea.

For example: a rectangular steel pipe with specifications of 50mm×20mm×3mm is 6 meters long, what is the weight?

Weight calculation: m=2×(50+20-2×3)×3×6000×0.00000785=18.0864(kg)

Classification of A500 rectangular tube:

Steel pipes are divided into seamless pipes and welded pipes (seamed pipes), such as hot-rolled seamless square pipes, cold-drawn seamless square pipes, extruded seamless square pipes, and welded square pipes. Among them, the welded square tube is divided into:

1. According to the process, it is divided into arc welded square tube, resistance welded square tube (high frequency, low frequency), gas welded square tube, furnace welded square tube;

2. According to the weld seam, it is divided into straight seam welded square pipe and spiral welded square pipe.
