Hydraulic shock analysis in thin pulse pipelines

conference paper

English

With the flow and pressure variations in thin pressured pipelines, pressure pump breaks, non continuous valve movements in these pipelines and with the external mechanical strains, there originate mechanical oscillations in pipeline. These are called mechanical shocks. Created mechanical oscillations expand by the pipeline and medium filled in the pipeline. When the mechanical vibrations amplitude overload specific level there can be some problems like pipeline, armatures and connected instrumentation destruction. So it is necessary to prevent these phenomenons and try to terminate them as possible. For proper pipelines mechanical vibration restrictions it is necessary to know their parameters.
