pressure waves applications in pipelines?

Answer 1

The engineering terminology is 'surge' pressure. For example if in a long pipeline a valve closes at the end the pressure can continue to build way beyond the discharge pressure of the pump feeding the pipeline. The kinetic energy of the fluid in the line is converted into pressure energy and it takes time for the pressure wave to reach the pump and affect the rate at which the pump is putting fluid into the pipeline. Engineering solutions may include designing the pipeline to withstand the pressure, limiting the rate at which valves can close or installing quick acting relief valves.

Answer 2

i have seen the use of surge suppressor/regulators used in the hydrocarbon pipeline field using a high pressure trap on the liquid side and the shock absorbed by the action of a piston with a regulated inert gas on the other side of the piston.

this was technology used by exxonmobil in the 60's and 70's.

now days, these applications are best handled by valve actuators and ramp drive prime movers in large pipelines.

if you have a system with this as a problem then you might find that you could devise some engineering controls to manage the problem.
