Pipero: Calculations You Can Hand Over
A field calculator toolkit for plumbing, gas fitting, and HVAC work, covering sizing, pressure tests, offsets, heat loss, tanks, and unit conversion.
Field notes
The toolkit is organized around fourteen calculators, with trade selection during setup used to prioritize relevant tools rather than remove the others. The page names methods and standards at the calculator level, including EN 806-3, Renouard low-pressure gas sizing, IPC 2021 tables, and a Huebscher equivalent-diameter method. It also draws a clear boundary around uncertainty: Pump and Tank is marked as a pre-sizing estimate and excluded from PDF reports because its coefficients are unverified.
