Profile pipes differ from standard pipes. Conventional metal pipes have a round section, while profile pipes can have a square or rectangular cross section.
The most common profile pipes have dimensions 20*40, 40*40, 100*100. With such sizes, a combination of quality and strength is optimal. Profile pipes of square or rectangular cross -section have 4 stiffeners, but their weight is much smaller than the mass of a metal beam with similar sizes. It must be taken into account that the small mass of profile pipes does not affect bends or strength. Thus, profile pipes can be used in complex structures, significantly saving material. Profile metal pipes are used in many types of production. For example, in the furniture industry, with chemical and food production. They are used for the manufacture of various types of structures. In the production of technical documentation and to fulfill the necessary calculations, it will be necessary to know the weight of the profile pipe.
With the same size and characteristics, the numerical value of the weight of the profile pipe can very much differ from the weight of the pipe with a round section. In addition, the weight of the profile pipe specified during production may differ from the actual weight. This is due to the fact that GOST provides for some tolerances for which manufacturers have every right.
When calculating the specific gravity of the profile pipe in production, a special weight table is used. It indicates the weight values of 1 meter of the profile pipe. When using the pipe weight table for calculations, it is necessary to take into account the possible deviations of theoretical values from practical. If there is no such table, to calculate the weight of the pipe, there is a special formula similar to the one used to calculate the weight of a standard pipe with a round section.
M.P. = (D-t)*t*0.02466
D – pipe diameter, in millimeters;
T – the thickness of the pipe wall, in millimeters.
There are special computer programs for calculating the specific gravity of standard profile pipes. To use this calculation method, you need to know exactly all the sizes and parameters of the profile pipe that must be made:
Pipe length;
Type of cross -section of the profile pipe;
The thickness of the walls of the pipe.
Only by all necessary values can you get an accurate calculation result.
