Pipe 159: scope, characteristics and weight calculation

This product is a round-shaped billet made of steel by molding. Previously, similar products were used throughout the municipal and industrial infrastructure. Our article will tell you about the modern areas of its operation, as well as about where and how the 159 bp pipe is used.

Pipe applications

Currently, these products are often used in the following cases:

• construction work;
• laying communications;
• construction of air-pressure lines;
• pipeline protection.

In the last paragraph, this steel billet is used as a protective frame. In fact, it plays the role of a cartridge in which another object is located. In the role of it often serves the plumbing line.

Technical characteristics of pipes with a diameter of 159 mm

Metal pipe 159x5 according to GOST 10704 91 should have a length of at least 5 meters. The thickness of its wall can be from 1.8 to 8.0 millimeters. Depending on this parameter varies the mass of the manufactured product.

It is measured and indicated per 1 linear meter. According to the GOST, this value can be in the range from 6.98 to 26.24 kg. Thus, the weight of 1 meter of pipe 159x6 is approximately equal to 22.64 kg.

GOST number 10704-91 regulates not only the weight of 1 meter of pipe 159, but also the maximum deviations in length and outer diameter.

As for the outer diameter, the permissible value of deviations here depends on the accuracy of production:

• if it is normal, the tolerance is ± 0.8%;
• with elevated ± 0.7%.

It should be noted that the existing deviations in the length and thickness of structures, can affect their weight. For this reason, the weight of 1 meter of a 159x4 mm pipe or the like will undergo certain changes. This is not to be forgotten.

The advantages of metal pipes

This product has a number of important advantages.

These include:

• wide range of applications;
• preservation of good operational properties throughout all service life;
• availability of products, due to their presence from a large number of suppliers;
• the possibility of acquiring and using second-hand goods having a lower price compared to new samples.

Special attention should be paid to the last point. Let us dwell on it in more detail.

Secondary use of pipes with a diameter of 159 mm

The main reason for the use of second-hand goods is its more affordable cost. At the same time, knowing certain subtleties, you can purchase samples that have quite good opportunities for further exploitation.

Features of the selection and use of used pipes

Used pipe products are great for organizing sewage systems. And this applies to both pressure and gravity of their type.

When choosing such a product, it is primarily not the weight of the pipe 159x8 mm that is taken into account, but the conditions under which it was used. In addition, one should not forget that the pressure in the system being created should be less than in the previous place of use of such blanks. These measures will help minimize the possibility of damage.

Tip! If necessary, you can extend the life of these products. To do this, they are cleaned of rust and treated with a composition that protects the surface from corrosion.

In addition to the sewage system, such products are also used when laying water pipelines. Only it is used not to supply water, but as a box for the protection of aquifers. The use of new pipe structures for these purposes is very costly and therefore impractical.

Used products are most often bought simply by weight, like scrap metal. Therefore, the purchase takes into account the thickness of the walls, which directly affects the final mass of the goods. Thus, the weight of a 159x4 mm pipe will be more than 50% less than that of a 159x8 mm product.

You should not purchase structures that were previously used for land reclamation. They will be badly damaged by rust, with the concomitant presence of shells and lime scale.

After purchasing this product, you should clean it from isolation. The easiest way to do this is in the case of a bitumen coating. It is much more difficult to remove the polyethylene layer with your own hands, but under it, as a rule, the metal will be in better condition.

Calculation of weight used pipe size 159 mm

When carrying out calculations one should first of all take into account that such products are solid or welded. Technical characteristics of the first of them are determined by GOST number 8732-78, the second - by GOST number 10704-91. In one and in another document tables with parameters of marked products are given. Including, from them it is possible to learn, for example, the weight of a pipe 159х5.

It's pretty simple to do this:

1. First you need to find in the appropriate document a table with the values ​​of the theoretical mass of pipes. The values ​​indicated in it are based on 1 meter of the product;
2. choosing a suitable wall thickness, we multiply the mass of one meter by the required length. As a result, we get the total weight of the structures, based on which, we can calculate the upcoming amount of spending.

For example, let's calculate the weight of 20 meters of welded products with a diameter of 159 mm and a wall thickness of 6 mm:

22.64 kg (weight of 1 meter of the product) x 20 = 452.8 kg

Approximately this will be the weight of the pipe 159x6 mm, length 20 meters.

Tip! When calculating the total mass of pipe structures, it should be borne in mind that the weight given in the regulatory documents may differ from its actual value. This is due to the peculiarities of technological processes at different manufacturers and the degree of wear of the product during its operation. Therefore, to obtain reliable information, it is best to weigh the steel products.

Simplify the task of calculating the mass of pipes will help a special program called pipe calculator. Instructions for its use is simple. To obtain the required value, it is only necessary to enter the length of the pipe, its outer diameter and wall thickness.

For a more accurate calculation, select the type of material or alloy from which the calculated structure is made from the drop-down list. In addition, this program allows you to determine the mass of square and rectangular pipes.

Conclusion

Pipes with a diameter of 159 mm are often used for laying various communications. Moreover, this does not always require the use of new products. For the construction of sewers or the creation of cartridges for water supply networks, second-hand goods are quite suitable. Their price is more affordable compared to factory originals.

They are usually purchased by weight, like ordinary scrap metal. Approximately determine the weight of the pipe 159 will help GOST Standards № 8732-78 and 10704-91, which, respectively, regulate the parameters of all-metal and welded products.
