Water Hammer Protection System

A water supply system is subjected to water hammer whenever there is a change in steady state condition such as pump stoppage, pump startup or valve closure.

As a system changes from one steady state condition to another there is a transient change in flow and pressures as the system settles to the final steady state condition.

The magnitude of transient pressures (or water hammer) and the time duration of the transient condition depends on the flow rate velocity,pipeline material and the system boundary conditions such as tanks, pumps, air valves, control valves and changes in pipeline diameter, the water hammer is a phenomenon generally known in the water industry.

So we make a comprehensive analysis for all the system components and their interaction by our “surge analysis software” to investigation suppress transient pressures to acceptable limit and avoid high pressure in water pipe line.
