Compensator Types

Rattay compensators are ideal components for accommodating any movements in pipes. They compensate movements that occur during operation, such as expansion, vibrations, etc. Various basic types are manufactured depending on the direction of the movement in terms of the pipe axis.

Axial compensators

These are used to compensate axial movements. By means of a suitable design, they can also absorb angular and lateral movement.

Angular compensators

They are suitable to accommodate angular movements and are generally equipped with joints that absorb the axial reaction forces. However due to these tension forces, they are not suitable for use as individual units to compensate combined movements. When pipelines are constructed, they are used to create joint systems that can easily accommodate large movements on any level.

Lateral compensators

These are used to compensate lateral movements (offset). They have braces that absorb axial reaction forces and are therefore not suitable for other types of movement. These braces are available both in a joint model and also a tie rod model.

As a manufacturer of the following models, we have extensive calculation procedures that allow us to design the parts to the optimum for the respective application.  
Our modern production procedures guarantee fault-free operation, long service lives and a high level of safety.
