Compensators are adapters a inserted into the pipe, which restrict the propagation of sound in the body or compensate changes in length of long pipelines.

  • they are represented by a resilient structural elements of different materials, which elastically and tightly joining two pipe ends,
  • eliminate thermal expansion pipe,
  • eliminating inaccuracies assembly,
  • suppress oscillations and vibrations in all directions.

Compensator types

  • Axial compensators (expansion and compression in the direction of the compensator)
  • Lateral compensators (deflecting sideways)
  • angular joints (angular deflection pipeline axis)
  • universal joints (a combination of all kinds of bias)
  • vibration damper

Compensator according to the type of connection to the pipeline

  • flanged
  • welded joints
  • Threaded joints

Compensators according to the material of the elastic element

  • Fabric compensators
  • Metal expansion joints
  • Rubber expansion joints
  • Teflon compensators

Fabric compensators

Are used for flexible pipe joints and are used wherever a variety of reasons not to use the classic rubber joints - especially in case of high temperatures ranging up to 1000 ° C.

Fabric expansion joints are used for particulate and gaseous media in a number of industries with the liquid components. The main advantage of fabric expansion joints is their ability to capture multiple dimensional movements due to its flexibility. They are made of asbestos-containing materials. Are produced based on silicon, glass fiber, aramid fiber and other needed for proper function of installation. Compensators consist of several or even several dozen layers. The corresponding composition of the layers is chosen with regard to the nature of media and operating parameters. The most commonly used materials for the construction of fabric expansion joints are: EPDM, Hypalon, glass, polyester, aramid, glass cloth, silicone, Viton, PTFE, steel and others. Operating temperature range: up to 1000 ° C.

Metal compensators

They consist of one or more multi-layer stainless steel bellows (bellows) and connections: flanged, screwing or welding. The types of steel compensators are: universal, lateral (side), angular (angle), axial (axial). They can be fitted to order inner sleeve. Types of steel used for the production of bellows and guide tubes are: stainless steel 1.4541 (AISI 321), 1.4571 (AISI316Ti) and others. Types of steels used in the manufacture of connectors and flanges are: carbon steel, stainless steel.
Operating temperature range: up to 600 ° C.
The working pressure range: from -1 bar (full vacuum) to 40 bar.
The range of diameters: from DN 15 to DN 3000 larger diameters available upon request.

Rubber compensators

They are used in all types of industrial installations, power plants, heating plants and sucking. Are installed at the pumps, motors, compressors, turbines, fans.

Sorts of Elastomer’s used for manufacturing on the side shown expansion joints are: EPDM, nitrile, chloroprene, SBR, Hypalon, Viton.
Working temperature range: from -40 ° C to 150 ° C.
The working pressure range: from -1 bar to 25 bar.
The range of diameters: from DN15 to DN3000.
Types conjunction with the installation of: fixed and loose flanges, threaded connections, mounting socket. Materials of connecting elements: galvanized steel, stainless steel, aluminum, cast iron. Standards of performance according to standards PN 10/16 (DIN 2501), ANSI 150 lb. and other. Additional accessories: motion limiter, vacuum reinforcement rings, Teflon inner lining, thermal protection possible.

Teflon compensators

Teflon compensators are used wherever it is required high chemical and thermal resistance. They compensate for thermal expansion, vibration and mounting inequality. A wide use in chemical, food and pharmaceutical industries.
Operating temperature range: up to 235 ° C.
The range of diameters: from DN 25 to DN 600th
They are made of multilayer bellows shaped PTFE (Teflon) with external stiffening ring.
Stabilizing rings are made of stainless steel.
The flanges are made of spheroidal cast iron, stainless steel or carbon steel.
