Slack Line Flow in Pipelines and How to Identify It


As geological and environmental conditions are diverse and pipelines are usually constructed in accordance with the surrounding terrain, there are many pipelines with great elevation difference. This can range from just a few feet up to several hundred or even thousand meters. This can result in slack line flow in the section after the peak. As a result, the energy of pump operation will be wasted, and various undesirable consequences may be caused, such as overpressure violation, cavitation or corrosion in the pipeline. While it is usually difficult to exactly predict slack line flow or the pipeline is already existing for a long time pipeline models can help to identify it. The online seminar  describes how such a model works and how operators can benefit from it.
