The pipe math you do twice on paper, done once on glass.
The Moment
The foreman wants an offset by lunch. The pipe is hot, the gloves are on, the sun is bouncing off the screen of a calculator app that was built for an office. By the third re-entry of the rise number, the run has changed.
The Fix
Eight calculators tuned to what the job actually asks for. Each one draws the layout with your numbers labeled on it, so the apprentice can verify the same picture before any pipe gets cut.
Offline. Pinch to zoom on the diagram. High-contrast UI tuned for sunlight and safety glasses.
What is in the app
- Simple Offset. Single-plane offset by a known distance. Eight standard fitting angles.
- Rolling Offset. Two-plane math for offsets that also shift sideways.
- Fitting Take-off. Center-to-end for elbows, with a note to verify against the actual fitting chart.
- Mitered Turn. Segment cut math for fabricating your own elbow from straight pipe.
- Branch Saddle, Thermal Expansion, Pipe and Water Weight, Reference Tables. Stub-in saddle depth, steam-run growth, hanger sizing, and a precision reference.
Diagram first. Every calculator renders a labeled drawing of the layout with your numbers on it. A second set of eyes verifies the picture, not the math.
