Reduction of Harmful Pressure Fluctuations in Pipelines by Means of Introduction of Energy Damping Segments

Abstract— Problems of water hammer reduction in the pipeline, as well as reduction of the oscillations amplitude of the high pressure wave with a relatively wide front are relevant in our time in the design of pipeline systems, especially for long sections of the pipeline. Dozens of new protective equipment have been developed in the last decade, but interest in the subject has not diminished. This work is devoted to the search for new ideas to achieve the operation safety of modern pipelines. In the article the basic idea of protection is formulated, and also numerical experiments for various schemes of installation of the considered equipment are carried out. The paper provides recommendations on the most appropriate placement of equipment, as well as discusses the issues of economic feasibility.

Index Terms— hydraulic schemes, pressure fluctuations, water hammer, long pipelines.
