Most power plant piping systems experience some level of vibration during operation. In some cases, the addition of restraints is required to keep operational vibration levels within acceptable limits. Vibration levels may need to be controlled to limit stresses in the piping or attached components, minimize wear on supports or other components, or prevent impacts with other piping or components. This paper discusses the use of dynamic restraints to effectively mitigate piping-system vibrations. Topics covered include: The effectiveness of using dynamic restraints for various sources of vibration; the effectiveness and applicability of various types of dynamic restraints; design considerations, including sizing and placement of dynamic restraints; and maintenance and testing considerations for dynamic restraints.
