Pipefitter Mate — the professional pipe offset calculator built for the field.
Enter your horizontal run and vertical rise, and instantly get the travel distance, pipe cut length, setback, cut angle, and inside/outside arc measurements. No guesswork, no manual trig — just accurate results you can trust on the job.
KEY FEATURES
Pipe Offset Calculations
Input RUN and OFFSET to calculate TRAVEL, PIPE CUT, SETBACK, CUT ANGLE, INSIDE ARC, and OUTSIDE ARC. Results update in real time as you type.
Elbow Cut Details
Tap ELBOW CUT to see exactly where to mark and cut your elbow — inside arc (primary cut line), outside arc (alternative wrap method), and setback from the elbow face. Supports both Long Radius and Short Radius elbows with mm/inch toggle.
Pipe Dimension Database
Choose from standard NPS sizes (1/2" through 8") with both Long Radius and Short Radius elbow options. Centre-to-end and radius values are built in — no need to look them up.
Multi-Stick Cut List
When your pipe cut exceeds stock length, the app automatically calculates how many sticks you need and generates a cut list. Weld gap is deducted per joint — exactly how you count gaps on site.
Configurable Stock Length
Set your standard pipe stick length to match your region: 6m metric, 20 ft, 24 ft, 40 ft, or enter a custom value.
Weld Gap Deduction
Set a root gap per weld joint and the app deducts the correct total across all joints — including elbow welds and mid-joint field welds on multi-stick fabrications.
CAD-Style Spool Diagram
A clear geometry visualisation shows your pipe offset with elbow curvature, dimension callouts, and weld joint markers. Pinch to zoom and pan for detail.
Save and Load Spools
Save your calculations for later. Name each spool and load it back with one tap — handy for repeat jobs or referencing previous work.
Metric and Imperial Units
Switch between millimetres and inches with a single tap. All values convert automatically.
BUILT FOR THE WORKSHOP
Dark industrial theme designed for visibility on job sites. Screen-stays-on mode keeps your phone awake while you work. Portrait orientation keeps the interface steady when you're holding a phone in one hand.
OFFLINE AND PRIVATE
Pipefitter Mate works entirely offline. No internet connection required, no user accounts, no data collection, no ads. Your calculations stay on your device.
Professional liability disclaimers are included. This app is a tool to assist — always verify calculations against project specifications before fabrication.
