Calculation method for determining the mass of steel pipe products
This method is not used very often, but is the only one when the exact length of the pipeline at the stage of design design is still unknown, and it is required to determine the maximum possible load on the supports and metal structures. The initial data for calculating the weight of rolled round cross-section are:
Radius of outer section of pipe R, mm;
Radius of the internal section of the pipe r, mm;
Length of the calculated section l of the copper pipeline, mm.
The dependence on which the calculations are made has the form:
M = 3.14 (R 2 — r 2) lρ,
Where ρ = 8960 kg / m 3 — the density of steel at room temperature.
Similarly, the weight of one running meter of non-circular steel pipes is calculated, but instead of the sectional area of the ring 3.14 (R 2 -r 2), the area of the hollow thin-walled rectangle 2t (B + H) is substituted, where t is the wall thickness of the pipe, H and B respectively — Length of the larger and smaller side of the pipe.
The density of steels of different classes is given below:

Approximate method for determining the mass of steel pipes
It is based on tabular data, which indicates the mass of one running meter of a steel pipe, depending on its diameter. For the most common sizes of sections, this information is given in the table below.
|Pipe weight steel outer diameter 48 mm (electrically welded)|
|Pipe weight steel outer diameter 51 mm (electrically welded)|
|The outer diameter of the pipe is 57 mm (electrically welded)|
|Pipe weight steel outer diameter 60 mm (electrically welded)|
|Pipe weight steel outer diameter 76 mm (electrically welded)|
|The outer diameter of the pipe is 89 mm (electrically welded)|
|The outer diameter of the pipe is 102 mm (electrically welded)|
|The weight of the pipe is steel outer diameter 108 mm (electrically welded)|
|Pipe steel steel outer diameter 114 mm (electrically welded)|
|The outer diameter of the pipe is 127 mm (electrically welded)|
