Based on the reasons of generating the water hammer in the pipeline running, effects of the water hammer on the upstream and downstream flow were respectively analyzed from the aspects of wave supercharging and wave decompressing. Several measures to reduce water hammer pressure hazards were outlined, such as regulating valve protection, pressure protection system and enhancing the ability of automatic control system protection. So it is very important to take effective line pressure protection system for the safe operation of the pipeline.
