Weight pipes: calculation using formulas, tables and online calculator

Weight pipes - is a parameter which determines the weight of 1 meter steel member. There are several methods you can use to calculate this indicator. These methods are somewhat different depending on the types of pipes with different cross-sectional shape. Determining the mass of the pipe - a serious event, you need to calculate the shipping cost and construction nuances.

For some purposes is determined by the weight of steel pipes

Steel tubes are widely used in the construction industry. In any project, you can find information on what has mass communication pipe, laid in the building. The same goes for other pipeline systems and structures made of rolled sections. By weight water and gas pipes of steel computed in several ways. What else is required calculation of the parameter?

The theoretical weight required for sale as the realization of the pipes is carried out taking into account the mass, not length. Thus, the definition of this indicator makes it possible to calculate the cost of a single party.

Calculation of the mass of these products used in the construction to determine the strength of the future construction. This option lets you know what load will be able to carry the frame, made of pipes.

Note! Finding specific gravity helps to increase the accuracy of calculations, because the real value often does not coincide with the guests.

And finally, the calculation of the weight of metal pipes made before product shipment. Transportation must be carried out on a special cargo equipment, taking into account possible load. At the conclusion of the contract, which specifies the number of items and their weight, you should be sure that the transport will be carried per trip.

Thus, knowledge of the mass of the steel pipe is a prerequisite if their acquisition. Of course, the purchase of the piece of data items not necessary in this type of calculation. Determination of weight in such a situation it may be necessary only in order to calculate the real value of the product.

How to calculate the weight of the pipe yourself: Recommendations

Calculating the weight of the steel part of this type can be performed independently (without the use of state standards). The first need to define the basic physical and geometric characteristics of metal rolling. Weight calculation round parts differs somewhat from the calculation of this parameter y of profiled pipes (rectangular and square).

To determine the weight of a meter pipe having a circular cross section, it is necessary to measure the internal and external diameters. For profile tubes required step is to define the width and height. If necessary, you can use the standard documentation, publicly available on the Internet. Corresponds to GOST contain all the necessary information about the pipes of any type. It is important to remember that there is a document for each variety of these items.

Many of the indicators (eg, length) can be determined independently by using construction tape. To the calculation was as accurate as possible, it is advisable to know the type of material, its brand.

Learn about how many weighs tube is possible without carrying out complex calculations. GOST, regulating metal tube-products contain a special table. They specify the main indicators characterizing the item (including ground). And also you can use the online calculator in which the algorithm for calculating the masses laid.

Advantages and disadvantages of steel pipes

Steel products have many advantages, which are recommended to pay attention. In the first place it should be noted that of the alloy parts have high strength characteristics. This fact causes them widely in the construction industry, where the strength of the product is one of the main indicators. A wide range of parts is also considered an important advantage, as it allows them to expand the operational scope. In the construction market, you can easily select the appropriate form and specification details.

Note! Manufacture and sale of these products are produced in running meters. Weight pipes - main features that influence the cost.

All steel pipe can be divided into three categories:

• round;
• shaped (square and rectangular);
• custom (polyhedral).

Major advantage inherent in this product is the fact that they have a high resistance to mechanical stress. Steel pipes are resistant pressure and shocks. It is worth noting that they have a reasonable cost and belong to the middle price segment.

A wide variety of types of parts allows their use in various fields: construction, business, etc... Steel products have a small measure of linear expansion. This is an important advantage, as many pipes expanding upon heating, and if they are placed in the coupler, this may lead to cracks.

In order to answer the question of how to calculate the weight of the pipe, you must familiarize yourself with all the methods, allowing to make this calculation. Knowledge of the mass of steel products required at all stages, from their purchase to assembly.

Terms weight calculation steel pipe

To many people, it may seem that the determination of the mass of pipes is a simple matter. However, this calculation has a lot of nuances that need to be addressed. First of all it is important to remember that when buying party of steel pipes required to make sure the weight of the test. Any discrepancies in the calculations could lead to the fact that the material is simply not enough.

Excess weight may affect the future performance of construction design. The load exerted on the construction, it should be within the limits previously calculated and specified in the relevant drawing. Weight 1 meter tube is calculated taking into account the grades of steel from which the product is formed.

It often happens that the actual weight of the pipe does not correspond to the specific weight prescribed by the regulations. This is due to the nature of production. The product is perfectly appropriate documentation, perform virtually impossible. Therefore, at a party specified allowable size deviation.

When determining the weight of a meter of steel pipe is recommended to use several ways. This will allow to reduce calculation errors to a minimum. If the weight is used to determine the formula, then it is recommended to double-check the accuracy of the final results several times.

weight Tube: How to perform the calculation of the mass in the procurement

Most often, producers who are engaged in manufacturing metal pipes of different types, sell their products in bulk. Sale of individual components is also produced, but its percentage is much lower in comparison with the large orders that package developers and private individuals.

Helpful information!Measuring the length of products, of which the one party is not a convenient solution. In order to simplify the implementation, the cost is calculated taking into account the mass of the party, which is determined based on the weight parts. To calculate it is necessary to know the weight of 1 meter tube. This is the fastest way to calculate, but it is not the best for the customer. This is due to the fact that after the use of steel pipes, as a rule, is a certain percentage of the surplus.

To determine the mass batch used in the production of two ways. The first one takes into account the use of on-line calculator. This program allows you to quickly calculate the weight of steel parts. Often online calculator posted on the company's website, which is engaged in the production of steel products. Thus, each customer can determine the appropriate mass of the party and immediately place your order in minutes.

The second method to calculate the weight of steel pipe for the procurement, - weighing. It is produced using special trucks. This operation is performed in 2 stages. The first thing the car (or trailer) is placed on the scale, which allows to determine its mass. Further, it is downloaded batch of metal parts. From the resulting figure is subtracted the original weight of the vehicle - it turns out the total mass of the party.

Each buyer can arrive at production, if you want to determine other characteristics of the party. For example, it may need to carry out the calculation of the number of pieces of pipes in one order. Also, it is often necessary to know the length of the article. As a result of such calculations will allow for the reservation is not by weight, and the number of packages.

Calculation of steel tubes: weight round products and especially of determining

Round tubes made from steel, are very popular when laying various communications. It is important to remember that these products have the features of calculation of weight. To determine this index you need to know some of the physical and geometric characteristics. Before starting the calculation you need the following data:

• wall thickness;

• outside diameter;
• sectional shape;
• steel grade (for the accuracy of the calculations).

The easiest way to calculate in this case - to use a special online calculator. Calculation of the weight of steel round tube with the help of a special program, which defines the formula for determination of the mass, is made very easy to quickly. All you need to do - to enter the necessary parameters of the items in the corresponding cells.

Note!It is important to remember that when calculating the weight of the body having a circular cross section, a major indicator is an alloy stamp. Experts do not recommend to carry out the calculation excluding this characteristic.

To find the desired value performs the following: volume of the material multiplied by the density of steel. density indicator for steel and is a fixed unit of 7850 kg / m³. Using such a calculation can determine the weight of any circular parts (e.g., weight of the pipe 76 mm).

Today, there are two methods that allow to calculate the volume of steel round product or part of a different material. The first of these involves the calculation of the preform (sheet), from which the production pipe. In the second case it is necessary to find the difference between the volumes of the outer and inner cylinders.

Formulas for determining the mass of round steel pipes

Calculation of mass produced using special formulas. To understand them, it is recommended to study the design stages and the values ​​used in this case in more detail. The first formula requires knowledge of the diameter of the steel product and the thickness of its wall. As an example of calculation is specified weight 219h8 mm tube. Initially, a determination is made of the surface area of ​​1 meter details. Such an equation is as follows:

S = π x D, where:

S - sectional area of ​​1m details;

D - diameter;

pi - the mathematical constant which is equal to 3.14.

In finished form (with the substituted values), this formula is as follows:

S = 3,14 x 0.219 = 0.68 m

After determining an area of ​​1 m of round products is necessary to calculate the volume of steel, the steel production cost of the parts. To this must be multiplied area ratio obtained earlier, the thickness of the pipe wall. For determining the weight of 1 meter tube strictly follow 2019h8 required calculations. Let us see how this is done, the example:

V = S x t, where:

V - the volume of steel consumed;

S - sectional area of ​​detail;

t - wall thickness.

After introduction of the desired values ​​the equation becomes:

V = 0,68 x 0.008 = 0.00544 m³

The last stage of determining the mass of a round steel product is multiplication of the volume by the density of the material. This option is contained in special tables densities. For steel, as mentioned above, a fixed value of 7850 kg / m³. Thus, the final step of calculating the mass of the steel pipe:

m (1 m) = V x ρ, where:

m (1 m) - m 1 mass of the product;

V - the volume of steel consumed;

ρ - density of the material.

The calculation of this formula is as follows:

m (1 m) = 0.00544 x 7850 = 42.7 kg

This method can determine the weight of the items of any width (e.g., the weight of 1 meter tube 219h10 mm). The resulting settlement figure may not match the table. The diagrams indicate the theoretical value of 1 meter. There are tables that contain mass value of products with a particular frame size in tons.

Note! The calculation of this type allows you to get a lot of 1 meter details. To find the total weight of the pipe, it is necessary to multiply weight for product 1 m length.

The second method of calculation of the mass of steel round tubes

There is another formula by which we can calculate the mass production of circular cross section. This method involves the determination of the amount of the outer and inner cylinders. The first step in this calculation is to find the area of ​​the outer and inner circular surface of the steel. Such a method allows to calculate the weight of the product of any size, e.g., weight of the pipe 159 or 219 mm. The formula for this calculation is performed:

S (outer) = π x D, where:

S (outer) - external surface area of ​​detail;

π – 3,14;

D - diameter.

After introduction of the necessary values ​​formula becomes more understandable form:

3.14 x 0.219 = 0.68766 m²

Next, you need to make computing the second area - the internal. For this it is necessary to take away from the outer section, from an earlier part thickness, multiplied by 2, and translated into the desired shape. The equation will be as follows:

S (inner) = S (outer) - t x 2; (T - the thickness of the items).

Ready-made formula looks like this:

0.219 - 0.016 = 0.203 m²

Then it is necessary to multiply the number Pi in figure resulting from previous calculations. This will determine the inner diameter, which is necessary for calculating the weight of the pipe 219 mm. Ready-made formula:

0.203 x 3.14 = 0.63742 m²

The next step involves the subtraction of the outer diameter of the same index, corresponding to the inner side of the part. The result is a ready-made the difference, which is 0.05024. It should be multiplied by 1 m, which will translate into a number of cubic shape (m³). The final step in this series of calculations is to determine the weight of the product. To this must be multiplied by cylinder volume difference by the density of the material, which will calculate the weight of one meter of the product. The final calculation is as follows:

0.05024 x 785 = 39.4 kg

It should remember that the difference between the results obtained using two different formulas, is not critical. Both values ​​are also different from the table the weight of 1 meter steel pipe with a round such dimensions. This can be explained quite simply. The computation of this index is generally considers allowable errors in size, which are set in the respective guest, whereas in the formula discussed above were substituted standard values.

How to calculate the weight of the shaped tube (square or rectangular)

Formulas that are used to find the mass of round pipes are not suitable for determining the weight of core products. Round of metal species is more common, as is more often used in the construction and business areas. Sectional tubes differ in that they have a different cross-sectional shape. On sale you can find such variants of these products:

• square;
• rectangular;
• rhomboid;
• oval;
• trapezius.

To find the weight of steel profile pipes there are several ways, as is the case with round parts. Such products are used in construction, often for the organization of intermediate floors. With them mounted frame structures (both simple and complex).

Helpful information!The simplest options carcasses are used in the construction of greenhouses in suburban areas, as well as to create a garage structures.

The use of rectangular or square of metal in construction requires precision. Weight of product calculated in advance and specified in the design documentation. Proportion shaped tube can be determined independently using special formulas. To calculate the square mass products following equation applies:

m = (ρ) x 0.0157 x t x (A x 2 - 2.86 x t) x L, where:

ρ - density of the metal;

0.0157 - constant for calculating the specific weight;

A - side length;

t - the wall thickness of the article;

2.86 - a constant value;

L - length of the pipe.

The above formula allows to determine the mass of a single part with a square cross-sectional shape. The weight of the party in this case is calculated very simply. To do this, multiply the weight of the product by the number of pipes. For rectangular parts has its own formula, with which is determined by weight (e.g., weight 40h20h2 shaped tube). Such an equation is as follows:

m = (ρ / 7850) x 0.0157 x t x (A + B - 2.86 x t) x L

The values ​​of A and B correspond to the length of the sides of a rectangular metal piece. It should be noted that the data obtained from the use of these formulas may differ from table numbers. However, this difference is quite normal.

Method for calculating the weight of square pipe: popular options

Mass products made of steel and having a square cross section, can be determined by various formulas. there are certain nuances that you need to know during the geometric calculations. In most cases, the weight of the steel parts with a square cross-section is found by the formula, involving the multiplication product of the walls on its volume density.

The specific density of the steel product is a fixed parameter, which is 7850 kg / m³. Application of the method, which takes into account the use of third-party volume and density, allows to determine the weight per meter of profile pipes pretty accurate.

To find the weight meter parts Formula most commonly used, wherein the thickness of the product to be multiplied on the wall area. The area is determined by multiplying the length of the items in its width (the rectangle). The resulting number must be multiplied by 4 (the number of walls in a square tube). After calculating the weight 1m details must enter the value obtained in the final equation allows to calculate the mass of the entire product. Consider this formula:

m = t x 7850 x 4 x 1 x A where:

A - product dimensions;

t - the thickness of the wall parts.

Note!To determine the mass m 1 is easiest to use table weight of steel square tubing.

Another popular method by which the mass of the square steel pipes, involves the use of formula, having a constant:

m = (A - t) x t x 0.0316, where:

A - product dimensions;

t - the thickness of the part.

An example using this formula it is possible to determine the weight of 1 meter tube 80h80h4. Ready equation containing the substituted values ​​will be as follows:

m = (80 - 4) x 4 x 9.6 = 0.0316 kg

However, the method allows for the use of these formulas, still is not the most simple and fast. If necessary, you can determine the mass m of the article using a table containing all the necessary information about the rolled steel. Such tables are arranged in CCITT regulating one or another kind of rolled metal.

How to calculate the weight of the shaped tube: Table

To calculate the specific weight of the profile can be used various techniques. The most popular of these is a tabular method. The use of special tables that can be easily found in the regulations, allows you to save time required for the calculation. The schemes are contained all the necessary geometric parameters and physical characteristics, which include weight.

Weight Tables 1 meter steel pipe include already calculated data, which is easy to determine, focusing on the part dimensions. With these tables, you can quickly calculate the total weight of the shaped article. To this must be multiplied by a value corresponding to the weight of 1 meter, of the pipe length.

It should be noted that there are special tables that indicate the number of meters in 1 ton of product. Use tables weight of steel shaped tubes is very simple. The data from these tables can be used not only for determining the weight of 1 meter, but also for other, more complex construction calculations.

Methods for determining the weight of the welded steel pipes

Weight of electric parts is dependent on several factors. Primarily it should be noted indicators such as the specific density of the material. Of course, an important role is played by the geometric parameters of parts. The most important of these are:

• diameter (For round parts);
• width and height (for profiled rolling stock);
• thickness;

• length.

Note! For the calculations to be understood that the details of specific length when determining or (as it is called), the theoretical weight is equal to 1 m.

The density of the material - a constant value corresponding to the number of 7850 m³. To determine the weight of electric-welded pipes used methods:

• of formula;
• table;
• online calculators.

Each of the above methods involves obtaining values, which is not ideal. The final result is an approximation, affect several factors. For example, a fixed density value (7,850 m³) is used to calculate the specific weight of all varieties of steel pipes. However, the different steel grades are used for each type of parts. Thus, the fixed value has an influence on the final result, which is different from the actual.

The difference in the density of different steel grades not strongly felt in the calculation, if the party is not large enough volume. Tables welded steel pipes weight and are approximations. In addition, the final results contained in the tables are often rounded (for convenience).

Another reason for approximate calculation is that the ideal size parameters used for calculations. They tend to be different from the actual, as it does not allow for rounding the corners of pipes. Rounding may be present as a parameter in profile pipes. How heavy is the product? The best way to answer this question, use the table or the online calculator. This will save time.

Real detail of different precision welds. Such sutures may have different metal nodules. Another factor influencing the inaccuracy of the calculations, - production tolerances. Universal method for determining the mass - the use of formulas. But more often, this option is not justified, because not everyone will be able to carry out complex calculations, taking into account the use of a plurality of auxiliary geometrical and physical parameters.

weight calculation of stainless steel pipe: workflow and features

Pipes manufacturing material which serves as stainless steel, differ from conventional steel products in that they are more resistant to adverse operating conditions. For example, they, unlike the conventional steel pipe has high resistance to rusting.

Helpful information! It is worth noting the increased strength data items, which is reflected on expiry.

How to calculate the weight of the part made of stainless steel? Such an operation is not very complicated. To determine the specific mass must multiply the parameters such as material density and volume. In turn, in order to calculate the volume of product required to multiply workpiece surface area and wall thickness.

Consider how to determine the weight 57h57h3 mm pipe made of stainless steel, for example. In this case, the calculation includes 3 stages. The first formula will be as follows:

S = B x L x 4

S - area;

B - width of the wall 1;

L - length of the product;

4 - the number of walls.

With ready-completed equation looks like this:

S = 57 x 6 x 4 = 1,368 m²

With this method it is possible to determine the mass of various sizes (e.g., pipe weight 108, 120 or 150 mm). After calculating the square stainless parts can proceed to the next step. The second step takes into account the definition of the pipe volume. For this, as mentioned above, it is necessary to multiply surface area and wall thickness:

V = S x t

V = 1,368 x 3 = 4, 104 m³

Finally, after the evaluation of the volume of products can be found and its specific gravity. You will need to multiply the fixed density of steel, equal to 7,850 cubic meters, by the volume of the part. Consider the following equation:

m = V x 7850

m = 4,104 x 7850 = 3.2 Kg

To determine the mass of the pipe, made of stainless steel, there is another, more simple method. It is suitable for round parts. To carry out the computation required to subtract from the outer diameter of the wall thickness. Then, the obtained difference is multiplied by a fixed number and thickness of which is 0.025 kg.

The formula for calculating the weight of the pipes with non-standard section

In addition to round and profile products, there is another common form - the pipe with non-standard section. Many people wonder how to find a lot of details. In today's market of steel pipes are the most common options such unconventional section:

• oval;

• trapezoidal;
• diamond-shaped;
• pentahedron;
• Hex.

On the Internet you can find a table of weight pipes with non-standard section. In addition, there are special formulas that allow to carry out an independent evaluation of this parameter. The operational scope of such products is quite extensive. They are used for the installation of fences and other barriers of all kinds, as well as handrails. In the production of these parts are included in a variety of designs. To determine the specific mass of tubes having a nonstandard sectional formula is applied:

m = ρ x S x L, where:

ρ - density component material;

S - sectional area;

L - length of the product.

This formula is universal. Therefore, using it is possible to calculate the proportion of parts having different cross-sectional shape. The equation allows you to answer the question of how to find the weight of the pipe with non-standard section.

Note! In order to determine whether products meet the requirements of one party, declared by the manufacturer, it is recommended to perform a simple test. To do this, you need to decide the party 3-4 arbitrary details and to calculate the weight of each of them. Comparison of the data for showing the tolerance range.

If the pipe weight is already known, then it is possible to calculate the total length of the party. For this purpose there is a special formula:

L = m / ρ x S

The end result was as accurate as possible, it is necessary to take into account a number of other factors. Among them are the following: the composition of the alloy, the wall thickness uniformity of parts, the corrosion rate. Also, the mass is influenced by humidity and temperature.

Weight Table steel pipesTips on using

The source of the data in this case can serve as a special table. Her choice is made depending on the product type. Apart from the guests, the scheme can be found on many high profile sites. Today it is possible to find the Internet table easily to determine the mass of parts of different materials (e.g., iron pipe weight 100 mm).

Finding by weight tabular requires compliance with the two basic rules. First of all it is very important not to be mistaken with a choice of tables. To do this, you must check whether the name of the state standard of the material corresponds to the product, a lot of which you want to define.

The second rule - should not rely solely on the data defined in a table. Typically, the specific weight of the pipe does not correspond to the actual. Thus, any calculation is only approximate. For smaller parties, such a distinction is not a serious problem.

As an example we can take the dimensions 60h60h3 steel part. Weight 1 meter tube of this type is 5,25 kg if guided tabular calculation. It refers to the group profile and has an equal width along its wall. The actual weight of the product of this size may be different. Maximum assumption in this case is 10% of total weight (52.5 g).

The tabular method is very good in the case where you do not have time for lengthy, complicated calculations. However, always remember about the error that is present in this case.

Using an online calculator to determine the weight of the pipe

Online Calculator - a very simple way by which you can pretty quickly determine the mass of steel pipes. It is said that there are programs to calculate the weight of products made from other materials. Online calculator works on the propiska algorithm. The formula in this program takes into account the following characteristics:

• density;
• width and height (for profiled pipes);

• diameter (for circular products);
• wall thickness;
• length.

To use the calculator weight of steel pipes is very simple. All you need to do - to know the necessary values ​​and enter them in the appropriate cells. Many online calculators require a brand become knowledge. This enables a more accurate calculation.

Note! The calculator can conduct calculation parts made of copper, galvanized steel, stainless steel and cast iron.

It should be noted that the computation is efficient and can be performed even for the overall products (e.g., the weight of 1 meter tube 530x8 mm). When using the calculator you need to be careful. In case of improper filling the cells the result will be incorrect.

Weight of 1 meter of metal is determined in three ways: formulas, tables, calculator. Each of these methods is good in its own way, but they all have one thing in common - approximate calculation. Getting weight of 1 meter of metal allows us to calculate the weight of the entire party.
