Project Description
PIPENET Transient module is used all around the globe for rapid and reliable dynamic analysis of complex and simple networks. Some of the unique features of the Transient module are hydraulic transient forces, sophisticated control systems, priming and discharge time calculation
PIPENET Transient module is used for the analysis of the following types of system
- Firewater systems surge analysis
- Deluge system filling time calculation
- Elastomeric deluge valves
- Pipelines
- Loading/unloading systems
- LNG bunkering systems
- Turbine trip in power stations
- Steam hammer in main steam line of power stations
- Steam hammer in reheat lines of power stations
- Cooling water systems
- Water injection systems for reservoirs
- Time history for use with pipe stress analysis programs
The user has wide choice of models:
Pipes – elastic pipes, short pipes, dry pipes, pipe bundle
Pumps – simple pumps, inertial pumps, turbo pumps
Check valve – dynamic check valve, instantaneous check valve, inertial check valve, fluid damped check valve
Valves – extensive built-in valves, user defined valves, standard valves, control valves, surge relief valves, safety valves, relief valves, bursting (rupture) discs, regulators, air release/vacuum breaker valves
Tanks – Accumulators, air vessels, simple tanks, surge tanks, receiving vessels
Caissons – partially filled pump caissons, air release valves, built-in check valve
Control systems – pressure sensors, flow sensors, differential pressure sensors, transfer functions, PID controllers, cascade controllers, signal selectors, switches, pressure loss components, limiting power ramp, dead time
