Calculation of the weight of metal of different cross section by its size: basic methods and their features
Metal is the main material, used in many industries. Various designs are made of it. in addition, it is used as a material for the manufacture of parts and components of machines and units.
Metallurgical companies produce various types of rolled metal:
- corner;
- channel;
- pipe.
The most common is the pipe. When there is a need for this material, then it is important for the consumer to determine the characteristics of the metal, offered by a specific company-seller. To get this important information, they often refer to special tables. Focusing on data, contained in them, you can learn the most important parameters:
- weight;
- product dimensions.
If the company and the organization need metal pipes, then referring to the weight table, you can get all the important information about these products.
When metal is used for the construction of structures, then the most important thing is the correct selection of material. It must be of good quality, as reliability and service life of erected designs depends on it.
Often constructive elements are created, using profile pipes. Before purchasing material for their manufacture, you should learn the physical and technical characteristics of the material. Weight charts can help, which contain all the necessary information.
Turning to them, you can find out, what specific weight a separate pipe will have, and then on the basis of the obtained figures to calculate the weight of the structure.
Based on the indicators contained in such tables, you can determine the specific weight of the pipes, based on the size of the pipe products, as well as a number of other factors.
Why you need to know the specific weight of the profile pipe?
The importance of such information is great because, that profile pipes have some differences from standard plumbing products. Most often, the market offers pipes with a cross section of square or rectangular shape. The main advantage of such pipe products is their high quality and strength of steel, from which they are made.
At construction of various constructive elements profile pipes are widely used. They are widespread in various industries. When creating metal structures there is a problem in determining the weight of the product. To do this, the necessary calculations are performed. After their completion, the obtained data are entered when filling out the documentation.
Along with the responsible companies, there are also unscrupulous sellers in the market, which offering products, trying to deceive customers. Every year the number of pipe products from the Celestial Empire grows, which in their qualitative characteristics do not always meet the requirements of domestic production.
In the case of Chinese pipes, there is one feature, about which many potential buyers simply do not know. That's the whole point, that at these products on edges the thickness of pipes is defined. This is where measurements are most often performed. But the remaining sections of the pipe thickness is very small. Therefore, such a shortcoming can be identified, only if you determine the weight of the product.
Calculation of the specific weight of the profile pipe
To calculate the mass of a single profile pipe made of metal, you can use special calculators, which are on many sites of specialized companies. Using such a program, you can find out the weight of the pipe in a short time. Using such a calculator is quite simple.
action algorithm
Everything, what is required from a potential buyer of pipe products - enter in the fields of the program:
- the length of the pipe;
- profile length;
- wall thickness.
Then it remains only to choose the brand of steel, from which the product is made. When the "enter" button is pressed, the user can get a detailed calculation of the specific gravity of the metal. Using such programs, should know, that in most calculators the calculation of the weight of profile tubular products is based on the base value of the density of steel at the level 7850 kg / cube. m.
Using such programs, except mass, you can calculate the length of pipe products. In this case, you can accurately determine the running meter of the pipe, per fixed mass.
The formula for calculating the specific gravity of the metal
In addition to using a calculator, there is another method of calculating the mass of the tubular product. To do this, you can use the geometric formula for calculating the weight of the metal. First you need to know the area of the intersection, and then multiply by the length of the segment. The result obtained must be multiplied by the density of the metal, from which the product is made. You should know about it, that depending on the grade of steel, the density of the metal may vary.
How to determine the specific weight of metal?
The mass of the pipe is calculated according to the following formula:
М.П.. = S * 2 * (A + V) * ?.
In this formula, S is the wall thickness in meters, the letters A and B indicate the length of the profile in meters. And the density of steel is denoted by a letter?.
conclusion
Metal is the most common material, which is used in various industries. Different types of rolled metal are used for the manufacture of structures. Profile pipes are most often used. The use of high quality products ensures reliability and long service life.
Profile pipe products in a wide range on the market offers a large number of companies. Along with reliable sellers, companies also operate, which under the guise of quality products offer low-grade pipe products. Most often, they sell Chinese-made pipes under the brand of well-known manufacturers, which are not of high quality.
To buy really quality products, the organization or the enterprise needs to carry out calculations of weight of products at purchase of pipes, which they plan to buy. This will avoid buying low-quality goods and pay for a good profile pipe. Using an online calculator, you can get a quick calculation of the weight of pipe products. There is also a special formula, with which you can find out the weight. The resulting figure will help to draw a conclusion, which pipe the seller offers - quality or imitation.
