COMPLETW TOOL FOR NETWORK FLOW ANALYSIS

1 TMPIPENETIS THE SOFTWARECOMPLETW tool FOR NETWORK FLOW ANALYSISINTRODUCING PIPENETPIPENET is a powerful software tool forflow ANALYSIS of pipe and duct starts at the design phase,providing the means of performingcalculations such as pipe sizing and pumpselection under steady state conditions. At theother end of the spectrum, PIPENET computes the hydraulic transient forcesnecessary for pipe stress ANALYSIS and pipesupport design under transient runs under MicrosoftWindowsTM , making full use of thetechnology it offers.

2 The input is through pulldown menus, dialog boxes, etc. The outputcan optionally be sent to Microsoft WordTM orWriteTM for test processing and incorporationinto design is supplied as independentmodules, giving a choice of solutions for theuser's particular Standard Module is the perfect toolfor solving general flow problems withliquids, gases or Transient Module is ideal forunsteady state problems such as "waterhammer", "steam hammer" andcalculation of hydraulic forces necessaryfor pipe stress Spray/Sprinkler Module isexceptional for the design of fire protectionsystems, whether they be deluge, ringmainor is a very flexible program,offering a wide selection of units, userdefined pipe schedules, fittings librariesand pump characteristics.

Waterproperties are built-in and steam propertiescomply with the IFC67 Standard. A databaseof gases is provided in the program to whichuser-defined gases can be added.

4 With the PIPENET Standard Module thenetwork can be as simple or complex asnecessary, and can be made up of pipes, ducts,fittings, pumps, fans, check valves, controlvalves, nozzles, filters, orifice plates and othermodels. Control valves can be set for pressure,flow, differential pressure or valve range of fittings available in the programis from the Crane manual. The user can addothers which can then be stored in a PIPENET Standard Module has powerfulpipe sizing capability. The user can define pipeschedules from which theprogram will select the appropriatenominal and fans can be connected in series orin parallel, anywhere in the NETWORK .

5 ThePIPENT Pump/Fan Module can be used tocreate libraries of pumps and fans, which canthen be inserted anywhere in the PIPENET Standard Module includesseveral useful features, such as checking forcavitation, correction for ambient pressuredecrease with height, calculation of hydraulicgradients and modeling of leaks. Pressure loss Pipe sizing Pump selection Liquids, gases and steam Fittings libraryPIPENET - TRANSIENT MODULEThe PIPENET Transient Module provides aspeedy and cost-effective means of in-houserigorous transient ANALYSIS .

6 The PIPENETT ransient Module can be used for predictingpressure surges, calculating hydraulictransient forces or even modeling controlsystems in flow PIPENET Transient Module can modelnetworks with items such as pipes, operatingvalves, variable speed pumps, air release andvacuum breaker valves, accumulators,pressure and flow transmitters, PIDcontrollers and transfer functions to representthe dynamics of instruments and only can the PIPENET Transient Modulepredict cavity separation, it can actuallymodel its formation and wide choice of functions and tables areavailable for setting up boundary PIPENET Transient Module can find itsown initial and final steady states or use initialvalues given by the user.

7 The time step forcalculation can be determined by the programor specified by the user, as can time steps fortabular, graphical and forces the PIPENET Transient Module anyvariable can be selected by the user to beoutput in graphical or tabular form. Hydraulictransient forces can be output to a separatefile, which can then be used by pipe stressanalysis programs for further processing. Water hammer Surge ANALYSIS Hydraulic transient forces Cavitation modeling Graphical and tabular outputPIPENET-SPRAY/SPRINKLER AND HALON/CO2 MODULESThe PIPENET Spray/Sprinkler Module isspecially developed for the design of fireprotection systems in accordance with theNFPA13 and NFPA15 rules.

8 The PIPENETS pray/Sprinkler Module is ideal for all typesof water-based systems, including deluge,ringmain, sprinkler and foam PIPENET Spray/Sprinkler Module canbe run with several options for deluge andsprinkler systems. For example, with themost remote nozzle option, the PIPENETS pray/Sprinkler Module will determine thehydraulically most remote nozzle and set itsflow to the required value. The user canspecify the inlet pressure or flowalternatively, the overall flow density can bemade to match the requirements of the PIPENET Spray/Sprinkler Module isideal for firewater ringmain.

9 Pump selectioncalculations may be carried out, oralternatively, manufacturer's data for pumpscan be used. it is possible toperform calculations for different fire scenarios,and model breaks and blocks in the networkwith ease. Minimum flow control valves canalso be NETWORK in PIPENET Spray/SprinklerModule can have up to 5 pipe types, which canbe lined or unlined. The program has 8 pipeschedules built-in, and the user can add otherpipe schedules which can be stored in data are built-in, in compliance withthe NFPA PIPENET Halon/CO2 Module is suitablefor systems employing an inert gas such asHalon 1301 or CO2, complying with therequirements of the NFPA12 and NFPA12 Arules.
