Large scale piping systems are commonly used it transmit liquids and gases during process manufacturing and in power plants. Excessive piping vibration can cause serious problems. Fatigue in flanges, supports, and connections are the most obvious problems, but in some cases failure from pipe fatigue also occurs.
Particularly at nuclear power plants, operators are very concerned with pipe vibration. Downtime for power generation equipment can be extremely costly, and analysis of pipe vibration can become difficult if the right tools are not used. Pipe vibration can be caused by a variety of sources. Rotating equipment, fluid flow, and pressure pulsations are the most common causes. Additionally, many problems are erratic and do not manifest themselves when test personnel are present.
SignalCalc analyzers include capabilities that help users in analyzing piping vibration. The ability to set sophisticated triggering conditions to capture transient problems is often an important feature for diagnosing pipe issues. Learn more about Event Capturing.
Additionally, identifying the source of the pipe vibration can at times be required. Cross correlation measurements can be used for this task. SignalCalc Dynamic Signal Analyzers include correlations (auto and cross correlation) as standard features. Users also have access to a number of features that make this measurement possible, including the removal of mean value before correlation, user definable filters, and throughput recording for replaying multiple analyses.
Piping analysis may also be concerned with understanding the motion of vibration and potential structural fixes of the pipes and supports. SignalCalc Dynamic Signal Analyzers also have the ability to perform operating deflection shape and modal measurements on the same platform.
