Vibration elimination using viscodamper technology

Pipe vibration experts spend a lot of time analysing the causes of vibrations and implementing different mitigation methods for eliminating them. Viscous dampers have proven to be an interesting solution in many cases to address pipe vibrations in nuclear-, conventional-, and chemical plants.

This report provides description of the damper design and describes the efficiency of high viscous dampers in piping vibration reduction based on the application of the technology in several power plants and industrial facilities.

In accordance with experiences gained worldwide this report concludes that high viscous damper technology is one of the best solutions for vibration mitigation for piping and structural operational vibrations.
