Surge & Water Hammer Analysis In Pipelines
Surge and water hammer are critical challenges in fluid systems, often caused by sudden events such as valve operations, pump trips, or equipment failures. These events can disrupt steady-state fluid flow, leading to excessive surge pressures, increased pipe stress, and potential system damage.
At Dynaflow Research Group, we leverage our multidisciplinary expertise in both the dynamic aspects of fluid flow and the mechanical responses of piping systems to address these issues. Our comprehensive surge analysis services aim to assess and mitigate risks, ensuring the safe and efficient operation of your piping systems.

CHALLENGES WE SOLVE
Addressing Critical System Issues with Surge Analysis Services
- Large pressures: Can cause permanent deformation or rupture of pipelines
- Low pressures: Risk of pipeline collapse or leakage at joints and seals
- Reverse flow: Potential damage to pump seals and motors, and draining of storage tanks
- Pipeline movement: Overstress and failure of pipe supports and pipelines
- Low flow velocity: Can lead to the settlement of solids in slurry lines, causing blockages
- Large unbalanced loads: Vibration of mechanical structures, excessive loads on flanges and tank nozzles
- Cavitation: Occurrence can lead to problematic vibrations, unbalanced loads, and noise
