Rubber expansion joints
Long service life guaranteeing high operational reliability
STENFLEX rubber expansion joints impress with their compensating and damping material properties. Excessive force, arising within the pipeline, is deflected by STENFLEX rubber expansion joints before this can be passed on to adjacent components.
Our expertise, in designing and constructing rubber expansion joints, is reflected in their long service life and high operational reliability. This explains why most European nuclear power plants are equipped with STENFLEX expansion joints.
STENFLEX pipe connections are made of high-quality rubber. They are used in industrial environments and in plant and process engineering, as well as in mechanical engineering, in the production of motors and the construction of industrial equipment, and even in shipbuilding. They have also found their way into building services engineering, environmental engineering and hydraulics.
What STENFLEX rubber expansion joints do:
- Damp oscillation, noise and vibration
- Compensate motion
- Compensate expansion caused by differences in temperature
- Reduce tension
- Compensate ground and foundation settling
- Compensate imprecise assembly
- Serve as assembly and disassembly aids
- Provide an elastic wall seal for penetration assemblies
- Compensate pipeline movements aboard ships
Difference between expansion joints on the basis of movements
Universal rubber expansion joints
Structure: Rubber bellows with adapters (flange or thread).
Movement absorption: Axial, lateral, angular as well as combined movements are absorbed. Universal expansion joints, with two rubber bellows and a distance pipe, are used to absorb significant movements.
Fixed points: Stable pipeline fixed points, and a correct and proper pipeline, are required to absorb axial forces.
Lateral rubber expansion joints
Structure: Rubber bellows with lateral motion tensioning system and flanges.
Movement absorption: Lateral shifting of the expansion joint can be absorbed. The tensioning system absorbs axial stresses and relieves the load on the pipeline fixed points.
Festpunkte: Only light fixed points are required to absorb lateral displacement and friction forces.
Angular rubber expansion joints
Structure: Rubber bellows with tie bar and flanges. The centre of rotation, of the tie bar, is located in the centre of the bellows.
Movement absorption: Angular movements of the expansion joint are absorbed. The angular joints regulate a defined angular movement, absorb axial stresses and relieve the load on the pipeline fixed points. A distinction is made between hinged angular expansion joints (angular movement of the bellows is diverted on one level) and cardan-joint angular expansion joints (angular movement of the bellows is diverted on two levels). Angular expansion joints, with distance pipe, are used to absorb significant movements.
Fixed points: Only light fixed points are required to absorb angular displacement and friction forces.
