Rolling offset, takeout & ASME
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Pipe Calc is an offset calculator built for pipefitters, plumbers, and steamfitters.

- Simple offsets with any fitting angle (45, 22.5, 60, custom)
- Rolling offsets: true offset, travel, and roll angle
- Cut length with takeout charts for standard fittings
- Slope / grade calculations
- Reference Data: offline ASME pipe schedules & weights, fitting takeouts, flanges, gaskets, valves, line blanks
- Fraction-first input and results to 1/16"
- Big, glove-friendly controls
Built to replace subscription pipe trade calculators with honest one-time pricing.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Fitting dimensions in Reference Data now show the nearest 1/16" fraction (as ASME B16.9 publishes them) with the decimal alongside. Home screen tiles now grow with larger accessibility text sizes, so calculator names are no longer cut off. Restoring a Pro purchase is more reliable, and the rating prompt timing was adjusted.
