  • Weight of 1 meter of pipe with a circular cross-section

Pipes with a circular cross-section are widely used in construction, industry, agriculture, and municipal and private sectors. Structures made from this type of rolled metal must be strong and durable. Therefore, to calculate and achieve a reliable result, it's necessary to properly calculate the required amount of material before purchasing. This is where the question arises: how much does 1 meter of such a pipe weigh? Proper calculations allow the creation of a strong and reliable structure, efficient use of materials, and proper organization of its transportation and storage. It also helps in calculating the amount of material per ton and estimating its cost.

There are several options to find out the weight of the pipe:

  • Tables from relevant GOST and DSTU standards;
  • Mathematical calculation using a formula;
  • Engineering reference books;
  • Online calculators.

The choice of method depends on the customer's final goal. Some need highly accurate project calculations, while others only need approximate values. Professional engineers use theoretical weight calculations for one meter of pipe, taking the average value considering the external diameter and wall thickness, which can be found in reference books or state standards.

It is worth noting that the actual weight of pipes may differ from the values in the table because the actual wall thickness or external dimensions may vary within the tolerances specified in the DSTU.

If the pipe size is marked with an asterisk, it should not be used for new designs.

Since 2021, the DSTU 8943 standard has replaced GOST 10704 in Ukraine. The theoretical weight formula can also be used for pipe design and weight calculations.

Theoretical weight formula

m = ρ × V,
where: ρ — density of steel 7850 kg/m³.

The volume of the pipe is calculated as the volume of a hollow cylinder:
V = Sтр × h,
where Sтр — the area of the pipe's cross-section;
h — height of the cylinder, in this case, it will be the length of the pipe. We assume L = 1 because we are calculating the weight of one meter.

Since the pipe is cylindrical in shape, according to the general formula for a hollow cylinder, its cross-sectional area is:
Sтр = Sц = ¼π × (D² – d²),
where D — the external diameter of the pipe,
d — the internal diameter,
π — the number "pi," equal to 3.14.

Since the internal diameter d is unknown, it is obtained by subtracting twice the wall thickness s from the external diameter:
Sтр = ¼ π × (D² – (D – 2s)²).

Thus, the volume formula becomes:
V = ¼ π × (D² – (D – 2s)²) × L.

Substituting the volume into the mass calculation formula, we get:
m = ρ × ¼ π × (D² – (D – 2s)²) × L.

Simplified formula according to DSTU 8943:2019

The DSTU 8943:2019 standard offers a simplified formula for calculating the theoretical mass of 1 meter of pipe:
M = 0.0246615 × S × (D – S),
where D — the external diameter of the pipe,
S — the wall thickness.

There are also cases where it's necessary to determine the weight of a steel pipe already available in the household, and there is no caliper available. Using a thread and ruler, measure the length of the external circle, wall thickness, and the length of the pipe segment. Then use the calculation by imagining the pipe as a flattened sheet. The area of the external side surface is calculated using the formula L × height. L is the length of the measured circumference, and the thickness of the pipe segment is considered. We calculate the approximate volume and weight of our pipe. It is worth noting that this calculation is fairly approximate and does not provide precise results; it should only be used in household cases.

Considering the complexity of the calculations, the most accurate way to determine the pipe's weight is by using engineering reference books or GOST or DSTU standards, or other normative documents from Europe or CIS countries.
