I present a completely free, unique and innovative program for the Pipe Schedule sizing method within the NFPA 13 'Installation of Sprinkler Systems' Rules. You simply have to prepare your CAD layout drawing following a few guidelines as described below (as I am sure you already do) and AACALC12 will read this in, join all the pipes and heads together, size them to the appropriate table, provide a full quantities list that can be quickly priced up and to create another DXF file of the pipe sizes so determined for merging with the original drawing.

In my recent Email discussions with various Fire and Fire Protection authorities / associations around the world about my offer to produce specific software for their use / sale for the full hydraulic calculation of sprinkler protection systems in their own languages, it soon became clear that a vast majority of systems installed in most countries were, in fact, end- and centre-fed pipe arrangements of light and ordinary hazard sized to the NFPA pipe schedule method.

Unfortunately, there were then no programs to assist with such calculations, mainly because they are very easy to do and just not worth the extra time in preparing the information needed.

However, most sprinkler designers, contractors and installers now use CAD programs, either the free LibreCAD or paid-for, commercially available ones, to prepare their layout drawings (invariably a 2D plan) and this contains nearly all the information needed to determine the pipe sizes based on the number of heads it supplies. The only item missing is any change of elevation (rises and drops) needed to turn it into a 3D view so one can see elevations and isometric views. Neuview Media Player Professional 6.08 Serial here. Therefore if you draw out all the rises / drops as a smaller diameter circle than is used for the upright / pendent heads, and optionally give the positive (= up) or negative (= down) change as text (eg. +678 or -3000), then AACALC12 can incorporate them, size all the pipes and work out the elbows / tees etc. For the fitting and pipework quantities list. This page therefore describes all the options and features of my new ENGLISH only program if this matter is of interest and you seldom get involved in the full hydraulic calculation of looped, gridded, ESFR, roof/rack, special risk etc. Systems that all my other programs listed on this website can help with..
