Applications of PIPENET Transient Module

  • Pressure surge, water hammer, steam hammer analysis
  • Calculating discharge time of firewater systems
  • Hydraulic transient forces for pipe stress analysis, force-time history
  • Water injection systems – dynamic flow analysis
  • Transient analysis of subsea & cross country pipelines – hydrocarbons
  • Cooling water systems and fire water systems – pressure surge, water hammer and steam hammer analysis

PIPENET Transient Module Features

  • Initial state – steady state, user-defined, run-in time, final steady state
  • Output – graphical, tabular and forces output, snapshot, dynamic movie, min/max tables, pressure envelopes, hydraulic grade lines
  • Cavitation modelling – simple cavitation, discrete gas cavity model, unique channel cavitation model

  • Dry Pipes – rigorous modelling of initially dry pipes which fill with time, with or without cushioning effects.

  • Control systems – pressure, flow, differential pressure sensors, PID control, transfer functions, switches

  • Hydraulic transient forces – dynamic/total, unbalanced/complex forces

  • Force-time history neutral file output for reading by pipe stress analysis and finite element programs

Some of the unique features of the Transient Module are hydraulic transient forces, sophisticated control systems, priming and discharge time calculation.

  • Pipes – rigorous pipes, short pipes, pipe mile post data

  • Time step – fixed/variable, software/user-defined

  • Valves – operating, surge relief, control, non-return, swing check, regulating, bursting disk, inertial check
  • Pumps – simple, inertial and turbo pump models

  • Tanks – simple, accumulator, surge, receiving vessel
  • Vacuum breakers – with or without hysteresis
  • Caissons – partially filled pipes
  • Specifications – extensive range of boundary conditions

PIPENET Transient Module is used all around the globe for rapid and reliable dynamic flow analysis of complex and simple networks.

PIPENET Transient module has unique models such as the dry pipe model, with or without cushioning effect, in order to calculate the discharge of deluge systems accurately.  It has ground breaking channel cavitation models which can estimate the size and position of vapour cavities and their variation with time precisely.   It can model air entry into the system and the movement and size variation of air cavities and slugs along the network system.  PIPENET Transient module has powerful control systems capability without which many network systems just cannot be modelled.
