When it becomes necessary to calculate the characteristics or weight of a profile pipe, specialists use special tables that are compiled using GOST. In these tables you can find almost all the data you are interested in. If during the construction process you need to calculate the technical or physical characteristics of the product, in particular the weight of the profile pipe, then there is a separate table for this material, which will allow you to determine the mass by its dimensions. Sometimes tables are used to calculate dimensions based on weight.
Why would you need to know the mass?
Profile pipe is a product that, unlike standard pipes, has a non-circular section. The most common pipes are rectangular and square. The following dimensions are considered the most optimal: for square ones - 20X20 mm, and for rectangular ones - 60X40. Basically, such a pipe is used during the manufacture of various structural elements, often the weight of a profile pipe is set for the calculations necessary to fill out technical documents. In addition, there are often unscrupulous sellers who fraudulently want to cash in on us. There are casesimplementation of pipes, where the declared wall thickness of the products corresponds only to the dimensions at the edges, just where the measurements are made. For example, a pipe with parameters 100X100X5 actually has dimensions 100X100X4 in the middle. Thus, metal is saved, and, knowing the weight of the profile pipe, it is easy to identify the "shortage".
Calculation of Internet calculators
Calculation of the weight of the pipe can be done using simple calculations. There are many calculators on the net that help you clean up the weight. All you have to do is enter the known dimensions. Enter the length of the pipe itself, the thickness of the walls and sides of the profile. After that, designate the steel grade, and then press the "Enter" button. After this simple action, the weight of your pipe will appear on your screen with some error. As for the calculator that calculates the weight, the profile pipe is taken into account in them according to the data indicated in the tables. It is calculated by number, not by special formulas. In addition to determining the weight, depending on the given data, using a calculator, it is possible to determine the length, knowing the mass. Thus, it becomes possible to determine the number of pipes with a length of 80X80 per 1 kg.
Calculate using formula
A profile pipe, the weight of which is indicated based on the results of the calculation using a special geometric formula, may have an actual mass that differs from the calculated one. This is due to the fact that products do not always turn out to be an ideal geometricforms. Also, using a calculator, you can determine the mass of various other products: beams, corners, rods, squares, circles, etc. If construction is being carried out using a large number of pipes, it is not recommended to take into account the weight calculated by the formulas, as it may differ significantly from the real mass. Subsequently, this may lead to excessive overload of the support.
Conclusion
There are a lot of ways to measure the mass of profile pipes, but the most accurate will be the usual weighing with a scale. This is the only way pipes are released at retail outlets when they are sold. Now you know what weight the profile pipe should have and how to determine it!
