One of the differences between the Spray/Sprinkler Module and the other modules of PIPENET VISION is that, with the Spray/Sprinkler Module, it is not possible to enter a network until either (a) a Sunrise Data File (“*.SDF”) has been entered and saved or (b) an existing Sunrise Data File is opened. The Spray/Sprinkler Module complies with the NFPA rules, which are the universal rules governing the design of fire protection systems in the process plant industry, as far as hydraulic calculations are concerned. The Spray/Sprinkler Module is a steady-state modelling program for designing systems, with the objective being to ensure that the sizes of pumps, pipes, nozzles, etc. Where necessary, PIPENET VISION can be used to size orifice plates in order to balance or reduce the flow rates. The objective is to ensure that pipes, pumps, hydrants, nozzles and other items perform satisfactorily. With PIPENET VISION, it is simple and fast to perform these calculations. For these systems, it is usually necessary to perform calculations under several scenarios, such as different fire scenarios and different pump scenarios. Such systems are characterised by complex firewater ringmains, deluge systems, sprinkler systems, foam injection systems, etc. The Spray/Sprinkler Module of PIPENET VISION was specifically developed for the type of fire protection systems that are used in process plants and similar plants, such as refineries, petrochemical plants, offshore plants, and terminals.
