Surge Analysis
Waterhammer causes more problems than is usually realised. Surge pressures are often highest at start-up and shutdown but normal operation can also cause problems:
- Unacceptable high and low pressures
- Severe pipe loads
- Unwanted trips and shutdowns
- Pipe movement and vibration
- Bursting disc rupture
- Equipment damage
A surge study will show if problems exist and our consultants will propose the most effective solution technique, from a wide range of options including:
- Surge relief valves
- Slow valve closure
- Pump trips
- HIPS and OPPS
- Accumulators
- Bursting Discs
Surge pressures are generated and transmitted extremely quickly and hence need to be simulated by specialist techniques. Many dynamic simulators don't use these techniques and so are not suitable. Our programs are specifically designed for surge and so they show exceptional accuracy.
