Chapter 37
Pipe Vibration Testing and Analysis

Excerpt

In Chapter 37, David E. Olson provides a detailed discussion on pipe vibration, testing, and analysis with the aid of tables, figures, and references. David notes that for piping design and monitoring, vibration is typically divided into two types: steady-state and dynamic-transient. Each type has its own potential causes and effects, necessitating individualized treatment for prediction, analysis, control, and monitoring. In view of these factors, David discusses the experience of vibration with U.S. nuclear power plants and the allowable piping response, including industry Codes and Standards, regulatory guidelines, and acceptance criteria for steady-state and dynamic-transient vibrations.

David also provides a review of ASME∕ANSI O&M Standards and stress allowables. The coverage includes a commentary on the causes of piping vibration, including pump-induced pressure pulsations and flow turbulence; cavitation and flashing; vortex shedding; and water- and steamhammer. Discussed are the design considerations and guidelines for piping as well as the prevention and control from the plant design stage and the design practice. Because vibration testing is crucial for understanding pipe vibrations, it is covered with an in-depth commentary on its analytical methods. As he is conversant with ASME O&M Code Committee activities, David discusses piping-system vibration requirements for the nuclear industry.
