Bellows axial expansion joints UKSPAR: buy at the manufacturer's price
Bellows compensator is a necessary part for various types of compensation of various vibrations, hydraulic shocks, etc.You can buy a flanged or welded bellows compensator, made of steel or stainless steel, from UKSPAR, the official UKSPAR supplier in Ukraine. Models DN50–DN300 and larger are available, current prices are in the catalog.
The possibility of compression and stretching can be determined by calculating the linear expansion of a certain section of the pipe under the influence of sudden temperature changes.
The bellows compensator is used in the following industries:
- Central heat and water supply - the installation is performed between several supports of the stationary type in those sections of the pipe where the greatest length is noted.
- In heat exchangers, compressors, pumping stations - it is used instead of connecting elements to reduce vibration waves and noise.
- In boiler cooling systems, flue gas ducts, the axial compensator protects not only from vibrations, but also from thermal expansion of the working structure.
- In the gas and water supply system, it is used as flexible elements for the operation of shut-off valves.
In addition, some types are also used in aggressive environments, thereby compensating for various temperature deformations.
✓ Main parameters and characteristics
The steel axial compensator was made of high-quality material with an excellent degree of protection against negative corrosion. There are many models on sale that differ in various parameters and technical characteristics:
- The nominal passage DN varies from 50 to 300 mm (or more).
- The optimal pressure indicators are from 1 to 1.6 MPa.
- The main working environment is water (cold and hot), steam, gas, smoke, various petroleum products and others.
- The temperature of the working environment is from -20 to +300 degrees.
- The weight depends on a certain passage (DC) - from 5.5 to 41 kg (or more).
The range includes flanged and welded bellows compensators, as well as stainless bellows compensators (made of stainless steel AISI 304/316) for aggressive and food environments. The metal bellows-type compensator provides reliable compensation in systems with pressures up to 1.6 MPa and temperatures up to +300 °C.
According to the type of connection, the axial bellows compensator can be of several types - flanged and welded. Flanges have the greatest consumer demand due to simple installation and versatility in choosing the installation location. For systems that use rubber vibration inserts — Bellows expansion joints are used where metal construction is required.
A high-quality axial compensator can be fixed on any section of a straight pipeline. Moreover, during installation, the method of laying the pipeline structures between the guide supports does not matter.
✓ Basic rules for operation
It is recommended to install only one axial compensator between two fixed supports. It is not necessary to install the part in those sections of the pipeline where there are no supports.
In most cases, such elements are considered not unloaded, and therefore, are able to transmit the expansion force to the supports of the structure. All supports located in areas with unloaded elements must guarantee the load from spacer forces, from frictional forces, as well as from the weight of the entire pipeline structure. It is recommended to use unloaded bellows compensators in those areas where it is important to prevent load on the support.Depending on a specific task, there are different models of compensators that can be operated under certain operating conditions.You can choose and buy an axial bellows compensator — universal, flanged or welded — at a competitive price at Uxpar. The price of bellows compensators is formed taking into account DN, material and type of connection. Managers will advise and help you choose the optimal model for your operating conditions.
Delivery of certified goods is carried out regularly throughout Ukraine, as well as a self-pickup option from the warehouse by prior arrangement. The company's managers will advise each client and help them decide on the appropriate model.
