FitterMaster: Pipe Fitter Calc

FitterMaster is the pipe fitter calculator for the job site: pipe offsets with cut length, ASME B16.9 takeouts, flange bolt torque, miter and saddle templates. Fast, accurate and fully offline.

BUILT FOR THE FIELD
- Works 100% offline. No signal on the jobsite? Everything still works. No license checks, ever.
- Free to start. Go Pro with a weekly, monthly or yearly plan, or pay once for Lifetime. No account.
- Feet-inches-sixteenths input everywhere. Think in 16ths, not decimals.
- Full metric mode (mm) that actually works.
- Save your spools and reuse the numbers that worked.

PIPE OFFSET CALCULATOR (45 DEGREES FREE FOREVER)
- Set + roll to true offset, travel, and run for any fitting angle: 5.625, 11.25, 22.5, 30, 45, 60, 90.
- Cut length done for you: travel minus takeouts minus weld gaps. Mark the pipe and cut.
- Clear diagram with every result.

TAKEOUTS AND PIPE DATA
- ASME B16.9 takeout chart: 90 LR, 45 LR, 90 SR, 180 return, tees, caps - NPS 1/2 to 24.
- Odd-angle cuts: takeout and center-to-face to cut any angle from a standard 90.
- Pipe schedules 10/40/80/160/STD/XS/XXS: OD, ID, wall, weight per foot.

FLANGE BOLT TORQUE
- ASME B16.5 class 150/300/600: bolt count, stud size, stud length, wrench size and bolt circle.
- Star tightening sequence diagrams and 3-pass torque targets (30/60/100 percent).

TEMPLATES AND ORDINATES
- Miter elbows: cut angles, segment lengths, 16-line wrap template ordinates.
- Saddle-on tees and laterals: 16 numbered ordinates, ready to lay out.
- Dummy legs: on straight runs and on the back of a 90 LR ell - solved with real geometry, not approximations.

ACCURACY YOU CAN CHECK
Every multiplier, takeout, and ordinate is verified against published ASME B16.9 / B16.5 / B36.10 tables and cross-checked with independent numeric solvers. If you find a number that is off, we fix it.

FREE VS PRO
Free forever: the full offset calculator at 45 degrees (including cut length), Schedule 40 pipe data, and the tape-math converter (with ads). Pro unlocks every angle, every chart and every template and removes ads: choose a weekly, monthly or yearly plan, or pay once for Lifetime. Prices are shown in the app before you buy.

Made for pipefitters, steamfitters, pipe welders, plumbers, sprinkler fitters, boilermakers, and apprentices working toward their ticket.

COMMON QUESTIONS
Does it work offline?
Yes. Everything runs on the phone. No signal needed on the jobsite, and no licence check, ever.

Is it a subscription?
Your choice. Pro is a weekly, monthly or yearly plan, or a one-time Lifetime purchase that is yours forever. The free tools stay free.

What is free and what is Pro?
Free: the 45° offset calculator with cut length, Schedule 40 pipe data, and the tape math. Pro: every other fitting angle, odd-angle cuts, miter, saddle and lateral templates, dummy leg, the B16.9 takeout chart, B16.5 flange bolt-up, the other schedules, saved spools, metric mode, and no ads.

Does it do metric?
Yes, a full mm mode — it is part of Pro.

Where do the numbers come from?
Published ASME B16.9, B16.5 and B36.10 tables, plus plain trigonometry. Every result comes with its diagram.

Does it replace the spec or the drawing?
No. It is a field calculator. The isometric, the spec and your foreman come first.
