Metallic bellows expansion joints



Metallic bellows expansion joints are components for pipeline and machine constructions. They are capable, because of their material and shape, of compensating for movements, in addition to their sealing function. Metallic bellows expansion joints are used in:

• Power plants;
• Petrochemical industry
• Oil and gas industry
• Chemical plants;
• Cement plants;
• Gas turbine plants;
• DeNOx plants;
• Incinerator plants;
• Steel plants;
• Dehydration plants;
• Ship building and marine technology etc.

Operational conditions

Metallic bellows expansion joints can handle temperatures up to 1000°C.
The permissible work diameter up to DN 6000 mm.


• Highest flexibility and therefore the most allowance for movement with minimal installation height(pipeline distance).
• Reactive forces and adjusting forces are close to zero – for fixpoint calculations usually negligible.
• By using a variety of materials you can provide optimal and individual adaption to your working conditions.
• Cost effectively manufacture of large dimensions.
• Expansion compensation which leads to temperature differences
• Compensates for installation inaccuracies.
