A Surge Analysis: What Is It?
Surge analysis is the study of the pressure variations in a piping system and is normally caused by changes in the functioning of the system. These pressure changes can be as simple as the opening or closing of a valve or as complicated as
excitement or shutdown of one or many pump and so on, whether these are planned events or unplanned events. It is important to conduct such an analysis in order to be able to identify possible problems associated with pressure fluctuations.
Why is surge analysis necessary?
Surge analysis is important because pipelines, which are economical and safe means for transportation of fluids including both liquids and gases, are prone to abrupt change in pressure. These pipelines include basic components like valves, elbows, reducers, and in mid pipe courses there extent of curves and elevations also. In a pipeline system, disruption of flow of fluids often occurs due to emergency or operational conditions;
a situation that causes momentum changes that result in fast pressures. These pressure variations are very damaging to the pipeline and the organization of the pipeline can lead to very grave consequences. Hence, surge analysis is vital towards the design and management of installations to minimize such failures and guarantee operations.
When should one perform a surge analysis?
In current context, surge analysis is carried out whenever a pipeline system shifts from a design steady-state condition to any transient state as a result of some cause. These include any irregular events that change the flow and pressure rates for instance through the opening or closing
of a valve, beginning or stopping of a pump or any change in the operations. That is the reason why surge analysis is carried out until pressures and flow become steady and there is a new steady-state established. In particular, it is appropriate during the design stage or when major changes to the system are made, or when introducing operational changes to check the system and guard against failure.
Piping surge: what is it?
A piping surge refers to a situation where the velocity of a fluid in a pipe increases or decreases abruptly, most especially, when a pipe successively begins or stops pumping or a valve begins/ceases to open or close, or a displaced air in a piping system. This kind of variation can pressure elevate or drop in a very abrupt manner thus exerting pressure on the piping system
Surge analysis is then a specific hydraulic model that assesses the effects of these pressure variations on the pipeline system. Details relate to the maximum allowable operating pressures of valves, pipes and fittings, setting of pressures control and pump tripping, in addition to the feasibility, position and output of relief and any automated or remote control valves. It is for this purpose that this analysis is critical to assuring that pipeline system is capable of handling such surges safely and effectively.
Why is Piping surge analysis known by names such as transient analysis, pressure transient analysis and surge analysis?
Piping surge analysis is referred to by various names because each term highlights a different aspect of the phenomenon or the analysis process:Piping surge analysis is referred to by various names because each term highlights a different aspect of the phenomenon or the analysis process:
1. Hydraulic Transient Analysis: Stresses that the hydraulic conditions are temporary or short term in nature, stressing the changes over time of the actuality of the system fluid flow and pressure characteristics.
2. Water Hammer Analysis: Specifically, is the pressure fluctuation in the system due to the rapid variation of pressure such as closed and opened valve pressures which are normally attributed to liquid systems, and particularly water.
3. Pressure Surge Analysis: That is more concerned with the increase or pressure spike within the piping system which may be as a result of change of operation.
4. Transient Flow Analysis: Stresses temporary or changeable conditions of the flow in the system, not only pressure fluctuations but velocity and direction changes as well.
5. Pressure Transient Analysis: This is akin to hydraulic transients but differs in that regards pressure waves that are produced and propagated throughout the system when the system responds.
6. Fluid Transient Analysis: A term that can be used more generally for both liquid and gas systems in which the concern is with transient behavior of the fluid in the pipes.
7.Surge Pressure Analysis : It is the pressure change with respect to time or the pressure disturbances or pressure fluctuations. It mainly examines the maximum pressure that is experienced by the system in a given instance often during a transient event.
All these various names depict how according to the nature of the fluid within the piping systems, the causes of the transient events and the potential impacts that these have on the piping system, engineers may have different angles or areas of specialty to focus on while analyzing piping systems.
Analysis and Modeling of Surges:
KKR Bose Design, engineers therefore are expert in undertaking detailed surge analysis for entire pipeline system inclusive of pumps and valves. It starts with the collection of comprehensive data of the pipeline characteristics from the client. The key inputs required for performing surge analysis include:
– Pipeline characteristics
– Type of fluid
– Kinds of pumps, valves and fittings
With these inputs, surge analysis is performed with special programs for the analysis of these calculations. Potential inputs for the simulation may include; flow rates, control valve, operating condition, and valve closure which have to be manipulated so that the effect they have on the pipeline can be determined. This enables engineers to notice and address possible problems and want to have maximum efficiency of the given pipeline construction and functioning.
