Axial Expansion Joints

These expansion joints are designed to take up axial movements in a piping system. The advantage of axial expansion joints is the fact that they take up relatively little space and no directional changes in the piping are required. When installing axial expansion joints, proper fix points and guidance are required. Please consult our engineers for more information.

We offer two ranges of axial expansion joints:

  • Standard series: (axial) expansion joints up to DN150 (6″)
  • Industrial series: expansion joints > DN150 (6″) 
  • Depending on the required type, sizes in the industrial series go up to DN1.000 (40″). 

Besides our standard and industrial program, we also manufacture special expansion joints according to customers’ specifications. Diameters of several meters are no exception!

Lateral Expansion Joints

A lateral expansion joint works in the same way as a hinged expansion joint does. It utilizes the ability of a bellows to rotate in an angular direction. The lateral movement capability is the result of the angular rotation of the bellows and their centre to centre distance. The longer the distance between the bellows, the larger is the movement. 

A longer centre to centre distance also results in lower displacement forces of the expansion joint. Lateral expansion joints are independent expansion systems in contrast to single hinged expansion joints. They are practically a two pin system. Lateral expansion joints are usually installed with a 50% pre-stressing. This is accomplished by pre-stressing the entire pipe system after the expansion joint is installed.

Angular Expansion Joints

Angular expansion joints are used for large angular movement in one or two planes. Angular (or hinged) expansion joints are used for large pipe elongations. A system of expansion joints is made of standard elements. This requires two or three expansion joints. The application of angular expansion joints always requires a change in the direction of the piping. Therefore, they are preferably located where a 90° bend has originally been foreseen. The elongation absorption of hinged expansion joint systems is practically unlimited. It is determined by the allowable movement‘s angle of the hinged expansion joints and the length of the pipe section between two angular expansion joints. 


  • almost unlimited elongation absorption
  • reduced load on anchor points
  • modular concept application
  • use of normal guides

Metal Hose

Metal hoses are an indispensable part of modern technology with its high demands on piping systems for a wide variety of media and temperatures. High flexibility and highest pressure and temperature resistance characterize our product program and allow their use in many areas, notably in:

  • heating, plumbing and air conditioning systems
  • oil and gas industry
  • chemical and food industry
  • machine and equipment construction
  • ship building
  • railway and automotive engineering

Rubber Expansion Joint

Rubber expansion joints can be used in all industrial applications such as: 

chemical plants - heating systems - air conditioning - ship building - pipeline construction
Due to their extensive chemical resistance, they can be used in pipeline systems that carry various media such as:

  • hot water
  • cool water
  • warm water
  • compressed air
  • cooling water
  • sea water
  • acid solutions
  • alkaline solutions
  • oil and oil-containing media 
Rubber expansion joints are particularly suited to compensate mechanical vibrations, compensate axial and lateral movements, compensate installation misalignments and retain sound .
Rubber expansion joints with tie rods that are supported by rubber mountings are especially suited to retain sound and to compensate movements in plants where the installation of pipe anchors to withstand pressure thrust is impossible.
