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 needed 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 weight by its size. Sometimes tables are used to calculate dimensions based on weight.
Why do you need to know the mass?
A profile pipe is a product that, unlike standard pipes, has a non-circular section. Most often, pipes of rectangular and square section are found. 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 the profile pipe is set for calculations necessary to fill out technical documents. In addition, often there are unscrupulous sellers who want to cash in on us by deception. There are cases of pipe sales 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 in the middle has dimensions 100X100X4. 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 clean weight. All you need to do is make known sizes. 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, and not using 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.
Calculation using the formula
A profile pipe, the weight of which is indicated by calculation using a special geometric formula, may have an actual mass that differs from that calculated. This is due to the fact that the products do not always turn out to be in perfect geometric shape. Also, using the calculator, you can determine the mass of various other products: beams, angles, rods, squares, circles, etc. If construction is carried out using a large number of pipes, it is not recommended to take into account the weight calculated by the formulas, since it can significantly differ 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 using scales. This is the only way pipes are sold at retail outlets when they are sold. Now you know how much profile pipe should have weight and how to determine it!
