The main focus is vibration dampers suitable for piping applications, where both transient and steady state vibration are common problems that may be mitigated using vibration dampers.

Comparison of different types of dampers and their functions and capabilities including their advantages and disadvantages are highlighted, but also design and maintenance issues using vibration dampers to follow the special requirements at the nuclear power plants are described.
