Pipetionary: Piping Data

Pipetionary is a community piping reference for engineers, designers, inspectors, and field technicians who need dimensional data and quick checks on site. Its bundled catalog covers pipe dimensions by NPS and schedule, selected ASME fitting and flange dimensions, valve references, and gaskets. Explore interactive diagrams, save favorites and recent lookups, and search a technical dictionary in English, Spanish, French, and Portuguese. Calculators include hydrotest volume, Darcy-Weisbach head loss and pressure drop, and ASME B31.3 wall thickness. Pump Mate handoff is available when that app is installed. The bundled reference and calculator features work offline after installation. Opening external links and optional network services requires a connection. Pipetionary is free, ad-free, and requires no account. Pipetionary is a community reference, not a standards publisher or compliance authority. Verify values and final designs against the governing standard, project requirements, manufacturer documentation, and qualified engineering review.
