Vibration elimination using viscodamper technology

Updated 2025-02-13 Published 2020-07-01

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.

New method for investigating concrete structures in nuclear power plants

Nuclear power, which accounts for about 30% of Sweden's electricity production, plays a crucial role in delivering fossil-free electricity. As many nuclear power plants are approaching the end of their planned lifetime, it is crucial to extend their operating periods to meet current and future needs. Markus Nilsson at Lund University has spent four years investigating how non-linear ultrasonic methods can be used to detect and assess corrosion in concrete-embedded containment liners in nuclear power plants. The work has resulted in a doctoral thesis.
