It's all about their design features:

• The elastic element of the flexible insert is maximally resistant to aggressive environments. Constant pressure does not harm him hot water, and even after long use the element will not lose its functions;
• compensators are flexible enough, which allows them to successfully restore their shape after mechanical stress. In addition, the flexibility allows expansion joints to be installed in pipelines with little misalignment;
• Are the pipes exposed to shock loads, vibrating and making a lot of noise? All these problems will be eliminated after installing a compensator that successfully resists hydraulic shocks;
• heat resistance - flexible inserts are made of heat-resistant synthetic rubber of a special composition;
• light weight, making them very convenient to transport, and the installation process will not cause difficulties.

Flexible inserts will increase the service life of pipes

A flexible insert, also called a vibration damper, is an element whose main purpose is to reduce or completely eliminate noise. In addition, these parts eliminate vibration, absorb hydraulic shocks and compensate for displacements, shears and thermal elongations.

All these factors make vibration compensators indispensable in pipelines - they are installed in water and gas supply systems, air conditioning, etc. As a result, the service life of pipes increases significantly.

Vibrator insert- an element of a pipeline system necessary to compensate for displacements of various parts of pipeline systems that arise during their operation, such as mechanical, thermal or installation. You can select and order from the website catalog.

Rubber cord flange vibration insert It is also used to prevent the transmission of all kinds of mechanical vibrations in certain parts of pipelines. It can be successfully used as compensators in cases of any kind of temperature, linear or angular deformations.

If a pump, compressor, or ventilation unit or any other device, vibration inserts installed in front of or behind these devices significantly reduce the level of vibration and noise in the pipeline that may occur in these cases.

Scope of application of this element pipeline fittings unusually wide. Vibration inserts are installed almost everywhere where there is a piping system - in air conditioning and compressor installations, pumping stations. They are also used to facilitate working conditions for the installation and dismantling of valves; it is simply impossible to do without them on the suction and pressure pipelines of pumping or compressor units.

IN living conditions they are widespread in hot and cold water supply networks, in heating systems, as well as in sewer pipelines. To facilitate specific operating conditions that may arise during the operation of the pipeline, the selection of inserts is made by choosing from several varieties, which are produced for each nominal diameter of the pipeline.

For example, installing a butterfly valve instead of a gate valve is widely used to compensate for differences in the dimensions of the gate valve and gate valve. flange vibration insert, which is installed in series with the shutter. At the same time, the process of installing the shutter itself is significantly simplified and reduced in cost.

Shut-off valves for pipes.

Butterfly valves are a necessary part of a large process!

Shut-off valves for industrial and general use used in many areas of human activity - chemical, pharmaceutical, shipbuilding and many others. Valves are one of the main engines of many important technological processes. Butterfly valves- a necessary part of this engine.

Such a shutter both locks and regulates. He is the most important element pipeline, any oil pipelines. The main part of the butterfly valve is the rotary disk, which can be different materials usually made of stainless steel or cast iron.

Flexible rubber inserts (rubber compensators) are used as a protective element against strong vibration and water hammer in gas and water supply systems, pumps, compressors and other types of equipment.

Due to their high strength properties and versatility, flexible pipe and pump inserts are widely used in various industries industry and national economy.

Design and main functions

A ready-to-use rubber compensator consists of interconnected elastic elements and spring clamps(steel wires). Elastic element includes:

1. outer layer made of foamed porous rubber (neoprene EPDM);
2. plastic frame made of nylon fabric;
3. The inner layer of the structure is made of EPDM or NBR neoprene.

The material for manufacturing the flexible element of the inserts is heat-resistant from a complex of synthetic rubbers, physical properties which are superior to chloroprene and natural rubber.

Flexible rubber inserts have the following characteristics:

• impact resistance - withstand different types loads without delamination;
• non-flammability - safe to use at high temperatures;
• maintain the original parameters when the temperature increases (maximum - up to 100 degrees);
• resistance to pressure for a long time;
• high elasticity – adds strength under mechanical stress (compression, tension, angular and axial displacement, vibration);
• low weight.

The properties of rubber expansion joints allow them to be used to solve a number of different problems, namely:

• Ensuring the tightness of connections (reduces heat loss).
• Reducing or eliminating vibration levels.
• Absorption of noise during the operation of various mechanisms (pumps, pipelines, automated shut-off equipment, etc.).
• They take on the function of compensating for high temperature movements, as a result of which they can be partially deformed, preventing serious changes in the functioning of the mechanism (pipeline).
• Reducing mechanical vibrations in system operation.

Flexible inserts are used in systems carrying both air (technical) and liquid. The type of insert is selected based on the expected loads and the operating mechanism of the system.

Flanged and threaded

According to their design, inserts are of two types: flanged and coupling (threaded).

Flanged flexible inserts ( anti-vibration compensator) are a hollow core (elastic element) fixed between parallel flanges with a protective coating.

The main criteria and parameters for selecting flange inserts are as follows:

1. nominal diameter (25-1000 mm);
2. maximum working pressure (1.0-1.6 MPa);
3. number of holes on each flange (from 4 to 20);
4. compensated deviations:

• compression (19-26 mm);
• lateral displacement (14-22 mm);
• angular deviation (maximum at an angle of 15 degrees).
• stretching (12-16 mm);

Working medium for flange inserts: hot, cold, process water, solutions of salts, ethers and others. The temperature range of the pumped medium ranges from -10 to +110 degrees. Attached to the pipeline with a flange connection.

The elastic element of the threaded inserts is complemented by cast iron couplings, which consist of several parts. The metal part of the vibration insert is covered with a protective galvanized layer, which significantly strengthens the surface and protects it from the effects of the external environment.

Due to the fact that the flexible part of the coupling inserts has an elongated relief shape, the parameters and main functional characteristics of these models differ from flange inserts:

1. nominal diameter (15-80 mm);
2. maximum working pressure – 1.0 MPa;
3. compensated deviations:

• stretching (maximum – 6 mm);
• compression and lateral displacement (up to 22 mm);
• angular deviation can reach 45 degrees.

Temperature and composition requirements working environment threaded inserts match the flange ones.

Use in pumping plants and pipelines

Anti-vibration compensators are in demand in public utilities, processing industry, chemical and metallurgical industries. Particularly effective and reliable is their installation in pumping equipment and pipeline lines.

Despite the simplicity of the device, flexible pump inserts are not inferior to expensive and advanced devices with similar functions. Modern analogues, along with their advantages, also have a number of limitations, which narrows the range of their applications.

Flexible inserts for pumps have long proven themselves to be reliable, durable and “unpretentious” devices. They are used to reduce vibration load and protect sensitive system elements from movement of the working environment. They are able to reduce the force of hydraulic shock and increase the service life of mechanisms.

Flexible pump inserts can be effectively used in various types equipment: cooling coolers, ventilation and air conditioning systems, radiators and air compressors. For safety reasons, it is mandatory to use them in pumping units residential and public premises (schools, kindergartens, hospitals).

In pipeline networks, vibration inserts (vibration compressors) will play the role of compensator for thermal expansion of pipelines (within permissible deformation limits). In addition, they help reduce vibration and “operating” noise, and also increase the safety of the system.

Compensators various diameters applicable in pipeline networks of coolants, water (waste, technical), in residential and communal premises, manufacturing enterprises and other organizations.

“Pipeline” compensators allow:

• connect pipes with a sealed, elastic fastening;
• protect the most “fragile” elements of the pipeline from dangerous loads during system operation;
• compensate for pipeline deformations due to stretching and displacement of elastic elements;
• vary the direction of the pipeline system (elongation, longitudinal or transverse displacement);
• when executing repair work, the compensator can even out any discrepancies between the pipes.

Service life and endurance various types loads, make flexible rubber inserts the most popular vibration-reducing and compensating devices.

Vibration compensators (vibration inserts) belong to auxiliary pipeline fittings. The main purpose is to absorb vibrations created by other equipment in the system: pumps, compressors. They are also used to compensate for thermal expansion of pipes and lateral and angular displacement within the limits allowed by the design of a particular rubber compensator (depending on the diameter - up to 22 mm of lateral and 45° angular displacement). They help reduce noise from the operation of equipment that creates vibrations and protect against water hammer. Their work significantly extends the service life of the pipeline system, therefore they are necessarily installed after equipment that creates vibration, transverse and longitudinal displacement and stretching of sections of pipelines. Installed next to equipment that creates high vibrations.

Anti-vibration flexible insert design

A standard vibration compensator consists of the following parts:

• rubber sleeve or body;
• fastening to the pipeline system (2 flanges or threaded fittings);
• reinforcing cord

What materials are vibration compensators made from?

Certainly, different manufacturers may offer different versions of this equipment. We will tell you what materials are used in the manufacture of our anti-vibration inserts.

• Flanges/threaded connections: carbon steel.
• Reinforcing cord: carbon steel.
• Housing: EPDM (rubber).
• Rushwork vibration compensators also use an internal filler – nylon cord.

The maximum temperature of the working medium that the vibration insert can pass through depends on the material of the housing. As a rule, this is from -20 to +105-110°C. Vibrating inserts are used for hot and cold water, they can also be used when transporting air. For gases, vibration inserts with a sleeve made of MBR are usually used.

The rubber flange or coupling compensator is used both on horizontal and vertical pipelines. The rubber compensator is allowed to be used only for the specified technical parameters. Before installing rubber expansion joints, it is necessary to center the inlet and outlet pipelines. Installation of expansion joints is permitted only after the pipeline has been secured.

The nuts are installed on the side opposite the rubber elements. It is not allowed: twisting expansion joints; simultaneous operation in tension and shear modes; the use of expansion joints with a damaged rubber element.

It is not recommended to: paint the compensator or cover it with thermal insulation.

Rubber expansion joints must be installed and commissioned by trained and experienced personnel.

Installation diagrams for rubber expansion joints

Before starting work, completely remove the packaging and inspect the expansion joints to identify possible damage due to transportation or storage, in particular deformation as a result of external surface damage. The interior of the bellows must be free of any foreign bodies or materials. Only expansion joints in excellent condition are allowed for installation.

The expansion joints are equipped with rotating steel flanges, which simplify installation and prevent torsional deformation. The holes for the bolts (studs) must be accurately aligned with the corresponding holes in the counter flanges.

Only one expansion joint can be installed between two points (supports). Any expansion in this area between two fixed points must be less than the maximum compensating capacity of the expansion joint.

Install the compensator as close to the fixed point as possible. If the compensator is installed on one side near a fixed support, then a sliding support is installed on the other side. Otherwise, the sliding support is installed on both sides.
The distance between the support point and the compensator is approximately equal to twice the nominal diameter (2xDN, mm).

The configuration and dimensions of fixed points and sliding supports are determined by specialists from the installation organization based on the maximum forces and moments occurring in the system. Sliding support on the guide section must be long enough to avoid jamming.

Do not perform any pressure or leak tests on the system until correct installation fixed points, guide supports, connections, fixtures and other elements of the system.

The total length of the installation is equal to the construction length.

Using a compensator to compensate for misalignment of pipelines leads to a decrease in the compensating capacity, additional load and, as a result, a reduction in the service life of the compensator.

Expansion joints must not be subject to torsional deformation! Particular care must be taken when installing any type to ensure that there is no “twisting effect” on the expansion joint due to any stress on the pipeline.

Do not lift expansion joints with ropes or rods passed through the threaded holes in the flanges. If expansion joints are lifted through a passage hole, use a spacer to distribute the weight. Make sure that the forklift cables or forks do not contact the rubber part of the expansion joint. Do not place the expansion joint vertically on the edges of the flanges.

It is unacceptable to paint or coat the rubber part of the compensator with lubricant.

During installation, it is necessary to ensure that the bellows of the compensator is not damaged, and also to prevent foreign bodies from getting inside the compensator. The compensator must be cleaned inside and out and in this condition the compensator must be prepared for installation in order for it to function properly.

Transport bolts and studs should be removed, if possible, after completing the installation of the compensator.

Where possible, expansion joints should be installed in such a way that they can be regularly visually inspected for damage. Damaged expansion joints must be replaced immediately.

Should not be allowed sharp changes pressure in the system exceeding the design parameters.
