Water hammer analysis of Kenya No.1 Products Pipeline based on SPS software

To reduce the water hammer damages in pipelines, it is necessary to calculate the water hammer pressure that may occur in the pipeline operation for the adoption of protection measures. The water hammer pressure of a products pipeline when the pump unit in a pump station is shutdown is calculated by SPS software. The simulation results show that in the absence of any water hammer protection measures, the water hammer pressure caused by shutdown of the pump unit exceeds the design pressure of pipe network and facilities in the station and the design pressure of the pipeline between the stations. In order to ensure the safe and stable operation of the pipeline, a water hammer relief system with increased protections is proposed for prevention against water hammer. It is verified by the simulation system that this solution can achieve the control over the pipeline transient process.
