Component catalogue

The project catalogue has seven groups: pipes, emitters (with nozzles), tapes, valves and devices, pumps, fittings and wires. All internal hydraulic values are in SI.

Any item can also carry the FINAME code under which it is credentialed for financing by the Brazilian development bank BNDES; the bill of materials and the quote show it.

The editor shows and takes the values in the units of the project and keeps them in SI: in a US project, diameters in inches, classes and pressures in the pressure unit (psi, bar, kPa, ft H₂O), spacings and prices per foot, the flows of valves and the pump curves (Q@H, efficiency, NPSH) in gpm; a default metric project is unchanged. The exported CSV is in the units of the project too, with the unit in the name of each column (nominal_in, rating_psi, spacing_ft, maxQ_gpm, points_gpm_psi, cost_per_ft), and the import reads such columns and those of price lists ("DN (in)", "PN (psi)", "Cost (per ft)", q_gph).

The default catalogue ships 17 pipes (PE 16–50 mm, PVC DN 35–250, HDPE 110 and 160, 6" steel), 10 emitter families (PC and turbulent drippers, micro-sprinklers, PC bubbler, impact sprinkler, gun, garden rotor and spray, demand point), 6 tapes and driplines, 36 valves and devices (1" to 6", master valves, pressure-sustaining valves and hydrants with flow limiter among them), 18 pumps (centrifugal 1 to 100 hp, submersible 3 to 30 hp) and about 330 fittings generated for every nominal diameter (couplers, 90° and 45° elbows, tees, crosses, end caps, adapters and reducers, plus lateral take-offs, tape ends and risers) and 12 copper wires (1 to 10 mm² enabled, AWG 18 to 8 disabled: enable them where AWG is the norm), with translated names and illustrative prices. The PVC PN 80 pipes have the inner diameters and walls of NBR 14312 up to DN 150 and of ISO 1452-2 S 12.5 above, the PE PN 6 pipes the wall of PE 80 SDR 21, the impact sprinkler nozzles a discharge coefficient of 0.96 and every pump a motor its curve fits. A plausibility check runs over the default catalogue and every pack: the hoop stress of a thermoplastic wall against its class, a nozzle passing no more than an ideal orifice of its bore, the hydraulic power within 0.85 of the motor with its service factor (NEMA MG 1).

The editor (Design → Component catalog…) edits, duplicates and removes items, imports and exports JSON, CSV per group and Excel (export, fill in prices in the spreadsheet and import it back), sets the default catalogue for new projects (Use as default for new projects) and, as separate actions that each ask first, saying how many items leave and how many objects use them, Restore the factory catalog…, Load my default… and Forget my default…. An imported row without an id gets a stable one (from its supplier, code and name), so the same row imported again updates its own item and never another list's; replacing an item the drawing uses is warned about, and rows without a diameter, curve or section are left out with a warning. The CSV follows RFC 4180; the kv column is the flow coefficient of the data sheets (Δp = (Q/Kv)² bar) and kcoef the K of K·v²/2g; a PN without a unit up to 25 is asked about (bar or metres of head). An item switched off or removed that the drawing still uses shows as itself, marked, in the Properties.

Prices and currency

Every price of a project (catalogue, energy tariff, pivot machines) is in one currency, stored as an ISO 4217 code with the symbol shown in tables and reports (Design → Design parameters → Currency). A new project takes the currency of the machine's region when the system locale of the interface language names one (pt-PT → EUR, en-IN → INR, de-CH → CHF), else the currency of the most populous country of the language (pt BRL, en USD, es MXN, de/fr EUR, ja JPY, zh CNY, hi/mr/te/pa INR, bn BDT, ur PKR, ar EGP, ru RUB, tr TRY, id IDR, vi VND, ha NGN, sw TZS). The illustrative prices of the default catalogue and the default energy tariff (0.75 R$/kWh) are written in reais and converted with reference exchange rates (European Central Bank and exchangerate-api.com, 2026-09-21), so every language gets the same design; they only order the options for the economic sizing and should be replaced by a local price list. Choosing another currency asks whether to convert every price, with the reference rate offered and editable, and becomes the currency of new projects. The saved default catalogue remembers its currency and is converted for projects in another one. The gallery examples use the currency of their language (in the app, the user's currency). The list includes the Chilean UF (CLF), the inflation-indexed unit public subsidy contests ask budgets in (taken as CLP 40 000; type the day's value when converting).

Items without a price (manufacturer packs come without them) are reported by the design assistant (bom_unpriced); the bill of materials leaves them out of the totals and the economic sizing prices a pipe without cost in proportion to its wall cross-section, calibrated on the priced pipes of the same material, so the diameters keep their order.

Manufacturer catalogues (.oci.cat)

Fourteen packs ship with the app (259 items): Hunter, Rain Bird, Toro, Netafim, Rivulis, NaanDanJain, Jain, Nelson and Senninger (sprinklers, micro-sprinklers, drippers, tapes and driplines, pivot sprinklers, big guns, valves and regulators), Irritec (driplines and drippers), Bermad (hydraulic valves), Schneider (centrifugal and 4" submersible pumps, with curves measured at 60 Hz), and Amanco Wavin and Multilit (PVC irrigation pipes, NBR 14312). The data come from the manufacturers' published tables: nozzle curves q = k·H^x and radii R = a·H^b fitted by least squares to the pressure, flow and radius rows (the radius anchored at the design pressure), emitter constants, exponents, inner diameters and barb losses (Kd) as printed, pressure ranges and wall classes, valve losses fitted to the loss tables (or taken from Kv), and pump curves from the selection tables (pump efficiency estimated from the rated power, since the tables omit it). Each pack lists its source documents (sources). Prices are left at zero; a pack that carries prices states their currency (currency) and is converted to the project currency when added; a pump states the frequency its curve was measured at (hz), so on other mains (Design parameters) a fixed-speed pump turns in proportion. They live in catalogs/ as JSON files, one per manufacturer, plus an index.json.

Five generic packs, with no brand, hold thermoplastic pipes by standard: iso1452 (PVC-U by ISO 1452-2, PN 6 to 16), en12201 (PE 100 by EN 12201-2, SDR 26 to 11), is4985 (PVC-U by IS 4985, classes 1 to 6) and is4984 (PE 100 and PE 80 by IS 4984), dn 20 to 315 mm, 415 pipes generated by tool/gen_catalogs.dart from the tables of the standards with every wall checked against its class, and astm (PVC in inches by ASTM D2241, SDR 21 and 26, and D1785, Schedule 40 and 80). The first four carry reference prices with their source and date (pricesSource, pricesDate), shown in the Manufacturer catalogues… dialog and to the AI assistant: the 2024 agricultural price list of the Sardinia region (EUR, supplied and laid) for the ISO and EN packs and the 2023-24 schedule of rates of Maharashtra Jeevan Pradhikaran (INR, supply) for the IS packs, the published rows as printed and the other sizes from a fit by the mass per metre. Through the Manufacturer catalogues… dialog you add a pack to the project, import an .oci.cat file or load a pack or a whole index by URL, which lets any dealer or community keep its own repository. The project catalogue is exported in the same format. The complete format, with the fields of every group and the contribution rules, is in catalogs/README.md; dart run tool/gen_catalogs.dart validates the packs (unique ids, plausible curves) and rebuilds the index.
