Expansion joints

Frequent temperature changes or pressure changes as well as large/frequent load changes put a strain on the pipe system. Vibrations can also occur in pipe systems. Movable, metallic elements are used to counteract these disturbances.
In addition to expansion joints and metal bellows, these also include metal hoses, flexible pipes and pipe supports.
Expansion joints are required for the safe operation of systems in almost all technically oriented branches of industry. They fulfill tasks such as

Compensation of thermal expansion in pipelines
Decoupling the vibrations of elastically mounted units from the connected systems
Elastic compensation of relative movements between system parts
Isolation of structure-borne noise
Reduction of forces and torques at connections

Expansion joints are not only used in modern plant and equipment construction for technical reasons, they also meet other industry requirements such as

Increased economic efficiency
More compact system size
Ease of installation
Trouble-free operation
Safety in the event of malfunctions
