A Surge Analysis: What Is It?
Surge analysis represents a detailed study of variations of pressure inside a piping system due to operating conditions changes, and etc. They can cover from basic events like valve operation to elaborate situations of pump start or shut down (planned or not).
Surge analysis is essential to detect risks associated with pressure surges that may occur in the pipeline and makes the pipeline run safely and efficiently. It keeps the system integrity and prevents the pipes, valves and other essential components from being costly damaged. Surge analysis is necessary to hazard the risks with respect to pressure fluctuations and pipelin e operation to be safe and efficient. It is a key factor in ensuring integrity of the system and protecting against disastrous, expensive pipe line, valve and other component damage.
Why is surge analysis necessary?
Since pipelines for the transportation of liquid and gases are subject to abrupt pressure changes, surge analysis is an essential analysis. Fluid dynamics are complicated by components such as valves, elbows, reducers and elevation shifts. Sudden surges can occur due to adverse emergency events or operation changes. If not controlled, these can do great damage to infrastructure and disrupt services mayhem. Surge analysis reduces risks, failure, and ensures the reliability of pipeline performance during design
and operation. Together with pressure surges, if not carefully managed, they can inflict severe damage to the pipeline infrastructure and significant loss of business acquired from over pressurization. In the light of the above, it is imperative that surge analysis be carried out in the during pipeline design, operation, and management to mitigate risks, avoid failures and guarantee a reliable and safe system operation.
When should one perform a surge analysis?
Surge analysis was performed for the case when a pipeline is no longer in the steady state condition, but stays in one of the transient states which was caused by special changes for system behavior. Actions such as: valve operations, pump start-ups or shutdowns, or shifts in
operating conditions, etc. This analysis continues until pressure and flowrates stablize and form a new ‘steady state’. Therefore, it is particularly important during the design stage, after major pipeline changes, and when operations are changed so as to ensure that the system can sustain changes in pressure without causing failure.
Piping surge: what is it?
Generally speaking, a piping surge is a sudden and rapid increase in fluid velocity within a pipeline. This can cause pressure spikes and spikes or drop in pressure, thus exposing the system to extreme strain. Such events are analyzed using surge analysis to evaluate system behavior during such events and the maximum allowable pressure for the pipes, valves and fittings, and the relief valve and control system effectiveness. The goal is to be able to guarantee that the pipeline will withstand these transient pressures without failure.
Why is Piping Surge Analysis Known by Multiple Names?
The terms piping surge analysis are used interchangeably to describe a phenomenon and its analysis each emphasizing a different aspect of it.
Hydraulic Transient Analysis: Examines the transient condition of hydraulic conditions and is related to flow and pressure characteristics which are not temporary.
Water Hammer Analysis is the pressure surge normally occurring due to rapid changes in pressure which is generally related with liquid systems such as water pipes, etc, normally.
Pressure Surge Analysis: Which deals with the rise or spike of the pressure in the pipeline caused due to changes in operation.
Transient Flow Analysis: The analysis of fluid flow through the system under its temporary (variable) flow conditions – viz. the pressure, velocity or direction.
5. Hydraulic Transient Analysis: Analysis of pressure waves propagated in the system as a result of the transient events.
6. A general term encompassing both liquid and gas systems that pertain to the topic of analysis of the fluid transient behavior inside the pipes.
7. Surge Pressure Analysis: This one specifically looks at pressure changes over time as part of the transient event, and more specifically the maximum pressure the system sees.
describes how these terms reflect that while engineers can focus predominantly on different aspects of piping system behavior depending on whether the fluid in question is compressible or incompressible, the source of the transient events, as well as the likelihood of serious safety and performance impacts to the system.
