Application

Vibrations can be generated inside a system by mechanical or hydrodynamic processes, or may result from external sources such as wind loads, traffic vibrations, or earthquakes. Excessive vibrations can cause serious damage to pipe systems. Protecting them requires special components that do not restrain thermal displacements of the piping system. Viscoelastic dampers have proved in practice to offer reliable protection for pipe systems and installations. In particular, vibrations caused by sudden peak loads can be reduced to an acceptable level by such dampers.
