Automating Surge Analysis Studies Saves Time, Money

By Garry Hanmer, Product Manager, Atmos International Operations such as valve movements, pump power failures and pump start-ups can initiate sudden changes in the fluid flow velocity in a pipeline. These sudden changes cause transient pressure surges that can significantly damage a pipeline. Pressure surge can force the operating pressures above a pipeline’s allowable maximum and minimum pipeline pressures. High pressures can damage pumps, valves, and other pipeline equipment, or even a rupture. Vapor cavity closures can produce high shock pressures. Low pressures can cause pipeline collapse and cavitation. When unmitigated by surge protection, pressure surges can reduce the life expectan
