Draw the distribution network on the map, compute pressures and flows, check the code limits per pipeline class, size the diameters and generate the calculation report as a PDF. All in the browser, nothing to install.

Cartographic editor: supply points, delivery nodes, pipes, isolation and non-return valves, pressure reducers. Ground elevations filled in automatically.
Renouard formula and nodal method with Newton-Raphson iteration: node pressures, pipe flows and velocities, automatic handling of reducers and valves.
Maximum velocities and minimum pressures per pressure class, with the Italian pipeline classification (1st–7th species) built in and fully configurable standard profiles for your own scheme.
Diameter selection from commercial catalogues (PE, steel, or your own custom pipes) to satisfy every check with the smallest diameter.
Methane, grid natural gas, LPG, biomethane, hydrogen blends: free molar composition, viscosity correction for H₂-rich blends, altitude correction.
Network plan on a cartographic base, methodology and references, full results, verification outcome, pressure profile along the critical path, bill of quantities.
A high-performance numerical solver (sparse factorization) solves networks of thousands of nodes in seconds. A real-time log shows what the engine is doing while it runs.
Load a network from a GIS shapefile, GeoJSON or CSV — with column mapping for exports that use their own field names: nodes, pipes, reducers and valves are recognised, with checks that flag blocking errors and warnings before the import.
No black box: canonical cases worked by hand and checked against the engine, and every report includes an appendix that recomputes your network's critical path in full.
Three steps, from a blank sheet to a ready document.
Place the supply point with its pressure, the delivery nodes with their demands (Sm³/h, kW, kg/h…), connect the pipes along the real street layout.
One click: pressures, flows and velocities appear on the map. Non-compliant pipes turn red, with the detail of the violation.
Let Gasnetics pick the diameters from the catalogue, then generate the complete PDF calculation report, headed with your professional details.
A model built for project work: no subscription.
During the beta every feature is free: drawing, calculation, checks, sizing and the PDF report. Participants will receive complimentary credits at launch.
You pay only for the project you export, in proportion to its size: the credits needed grow in bands with the number of network nodes. Re-exporting the same project is free; a substantially changed network counts as a new report.
No subscription to remember or cancel: credits never expire — use them when the right job comes in.
The basics of gas distribution network calculation.
You start from the customers' demands and the supply pressure, compute the pressure drop of each pipe — for low- and medium-pressure networks the Italian and Spanish practice uses the Renouard formula — and pick the commercial diameters that respect the maximum velocities and minimum delivery pressures. Gasnetics automates the whole cycle: calculation, verification and diameter selection from the catalogue.
It is the classic correlation for gas pressure drop in smooth pipes in turbulent flow: P₁² − P₂² = 48.6·s·L·Q1.82/D4.82, with absolute pressures in bar, length in metres, flow in Sm³/h and internal diameter in mm. It is the reference formula of Italian and Spanish design practice for distribution networks.
The Italian classification of gas pipelines by maximum operating pressure: from the 1st class (above 24 bar) down to the 7th class (up to 0.04 bar, the low pressure of urban distribution). Velocity limits and minimum pressures are tied to the class; Gasnetics checks them automatically on the class declared by the designer — and configurable standard profiles let you define your own scheme.
Yes. The engine works on any mixture defined by molar composition: methane, grid natural gas, LPG, biomethane and hydrogen blends, with a viscosity correction for H₂-rich blends and automatic altitude correction even for gases denser than air.
Gasnetics generates a complete report: network plan on a cartographic base, input data, methodology with references, full results, verification outcome, pressure profile and bill of quantities. Results support the design work: the final check remains the professional's responsibility.
