GOST 24137–80 - U-clamp. Main characteristics and production features

U-shaped clamps are devices that are used to fasten pipes, as well as other elements. By means of such products, a pipe or hose is fixed on the surface of a metal sheet of any profile. Such a device has the form in the form of the letter “U” and is regulated by the relevant regulatory documentation, which indicates a list of diameters and other characteristics (GOST 24137–80 “U-shaped clamp”).

With the help of clamps, various types of pipes are fixed for vertical and horizontal installation

Key Features of U-Clamps

According to GOST, such a clamp is used for reliable fixation of pipelines. From a structural point of view, this device can be made in two configurations:

• a ring equipped with bolts;
• bracket in the form of the letter "U".

In the first case, the device can consist of one or two halves, and in the second, the bracket is equipped with a thread at its ends. Complete with such brackets in most cases are special trims. The bracket can be made with a layer of rubber on the inner surface. A layer of microporous rubber is necessary to damp the vibration effects that tend to occur in pipeline structures fixed to clamps.

These products are classified according to several key indicators. Consider these options:

• the material from which the part is made;
• cross-sectional indicator of the bracket.

Note! The range of these devices in terms of cross-section is quite wide (from 16 to 540 mm).

Clamps are available in different sizes and from different types of steel.

The cross-sectional indicators and the mass of clamps for fastening pipes according to GOST 24137–80 are presented in table No. 1.

Mounting brackets are made of various materials, however, the most popular are steel products. Today, there are a large number of steel grades from which various construction devices are made. U-shaped devices for fastening pipeline and other structures from steel are produced, which has a strength class of 4.6.

To protect against corrosion, the clamps are coated with protective materials - zinc, polymers and other

To increase their resistance to corrosion, these products, as a rule, are subjected to additional treatment with zinc (Zn). Such an anticorrosion layer has a thickness of 3–8 μm and reliably protects the device from rust.

Bolt locking elements differ from each other in one main indicator - the degree of tension. A different degree of tension of the clamp allows you to expand its operational scope and simplify installation.

Operational field and production features

According to GOST, pipe clamps are made primarily of carbon steel. Consider in which cases these devices are operated:

• pipe fixation;
• beam fixation;
• fastening road signs;
• TV antenna retention
• It is also used for installation-free sealing of various systems.

With the help of clamps, many types of pipelines and pipe structures are fixed on different surfaces and supports

Good to know! Such brackets are very popular when securing the connections of individual structural elements in automotive exhaust systems.In this case, the product is used to hold pipe-to-pipe connections.

The kit that is provided to customers typically includes the following items:

• the bracket itself;
• nuts (2 pieces).

As already mentioned above, these clamps are described by GOST 24137–80. This document indicates the length of the curved rod, which varies from 3 to 27 cm. And the cross-sectional indicators of such a rod can be from 0.8 to 2.4 cm. Storage and delivery of such products is carried out in boxes. The number of products in one box can vary from 5 to 100 pcs.

Consider the popular European companies that supply these fixtures:

• MKT;
• Fischer;
• Golz;
• Rottluff.

When choosing a clamp of this type, it is recommended to focus on the diameter of the pipeline or other structure that will be fixed by means of this product. In addition, it is recommended to study GOST U-shaped clamps.
