FLUID HAMMER IN FLUID TRANSMISSION LINES – a definition.
Fluid Hammer is a series of hydraulic shock waves generated within the confines of a piping system due to
the sudden stopping of fluid flow. This condition is caused by fast closing of positive valves incorporated within
the system. The effect of fluid hammer is damaging if allowed to exist for any length of time and will result in
broken pipes and damage to other components in the system.
