Pipetionary
ASME piping catalog & calcs
Free · Designed for iPad. Not verified for macOS.
Pipetionary is an offline ASME-based piping reference built for engineers, designers, inspectors, and field technicians who need dimensional data and quick checks at the jobsite.
It is not a repackaged website or a generic template app. The iOS app bundles a pre-populated SQLite reference database, custom React Native/SVG dimensional diagrams, four-language dictionary content, user preferences, favorites, recent lookups, and native calculators in one standalone app.
What is included:
- Pipes: browse ASME B36.10M and B36.19M pipe dimensions by NPS and schedule, with OD, ID, wall thickness, weight, fill percentage, and fluid linear weight views.
- Fittings: inspect ASME B16.9 and B16.11 elbows, tees, reducers, caps, socket-weld, and threaded components with generated dimensional diagrams.
- Flanges: check ASME B16.5 and B16.47 flange dimensions, classes, facings, bolt patterns, and key reference values.
- Valves: review ASME B16.10 face-to-face and end-to-end dimensions, plus curated manufacturer reference overlays where available.
- Gaskets: browse ASME B16.20 and B16.21 gasket references.
- Dictionary: search piping terms in English, Spanish, French, and Portuguese, including formulas, related terms, diagram references, and catalog links.
Engineering tools:
- Hydrotest volume calculator for line fill planning.
- Darcy-Weisbach head loss and pressure drop calculator.
- ASME B31.3 wall thickness calculator.
- Cross-app handoff to Pump Mate for extended hydraulics workflows when installed.
Why it is different:
- Offline-first app experience with bundled data, not web clipping or a link collection.
- Interactive, parameter-driven diagrams instead of static table screenshots.
- Standards-focused catalog coverage across pipes, fittings, flanges, valves, and gaskets.
- Four-language app and dictionary support for mixed-language field teams.
- Free, ad-free, no account required, and no in-app purchases.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Updated the offline piping catalog with clearer source and edition details, improved reference traceability, and visible coverage limitations. Also includes refinements to calculators, navigation, Settings, and English, Spanish, French, and Portuguese presentation.
