Pipefitter Calculator & Tools

Pipefitter Calculator & Tools is a practical calculation and fabrication reference app built for pipe fitters, fabricators, welders, technicians, and field professionals.

The app brings common pipe fitting calculations, spool planning, fitting references, and pipe data into one simple workspace. It is designed for quick use on the job without unnecessary menus or complicated controls.

Use the built-in calculators for everyday layout and fabrication work, including:

Elbow and bend calculations

Pipe offset calculations

Branch and tee calculations

Flange calculations and references

Spool cut length calculations

Flange-to-flange spool calculations

Valve spool calculations

Pipe and fitting dimensional references

Pipe schedule, OD, wall thickness, and ID information

Reducer and fitting reference dimensions

Circumference, arc, slope, triangle, and related field calculations

Pipe weight and volume tools

Saved projects and recent tools

2D Fabrication Diagrams

Calculation results include clear technical 2D diagrams where applicable. Dimensions, centerlines, cut lengths, fitting allowances, take-offs, and other relevant measurements are shown visually to make results easier to understand in the field.

The diagrams support zooming and panning for closer inspection.

3D Fitting and Spool Views :

Supported tools also include static 3D reference views to help visualize fittings and spool geometry.

The 2D and 3D spool views use the same calculated geometry so the visual representation stays consistent with the entered measurements.

Spool Builder :

Build a spool using straight pipe, elbows, tees, reducers, valves, and flanges. Review the spool in 2D or 3D, calculate overall dimensions, fitting allowances, weld gaps, pipe cuts, and generate a basic cut list and bill of materials.

Pipe & Fitting Data :

Quickly reference common pipe sizes and dimensional information using NPS/DN and schedule selections. View pipe OD, wall thickness, ID, and supported fitting data without leaving the calculation workflow.

Projects :

Save useful calculations and spool information as projects so you can return to them later without entering everything again.

Pipe Fitter Tools is designed as a straightforward field utility. Open the app, choose the required tool, enter measurements, and get the result.
