Pressure transients occur in pipeline systems when there are changes to the system boundaries. There are a number of practical, economic, methods of avoiding such damaging transients and achieving code compliance. This presentation discusses the various merits and pitfalls associated with such devices and methods. The various codes and standards requiring compliance are also mentioned.

Codes and standards require that the occasional loads in a pipe system be determined in order to establish the design pressure. Without an analysis of these dynamic loads the design pressure cannot be determined. The methods of analysis are also addressed by the presenter.
