PipeFit Pro: Pipe Calculator
Pipefitter Offset Calculator
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Your chart book, tape math and calculator in one app. ASME take-outs, every cut length in seconds, fully offline.
The ultimate tool for pipefitters, welders, plumbers, and HVAC professionals. PipeFit Pro is engineered to eliminate guesswork, save time, and prevent expensive mistakes on the job site.
Stop struggling with complex trigonometry and fractional math in your head. Whether you are calculating a rolling offset, a mitered bend, or trying to add fractions with thick gloves on, PipeFit Pro handles the dirty work in seconds.
CORE FEATURES BUILT FOR THE FIELD:
INSTANT OFFSET CALCULATOR
Calculate Travel, Run, and Set for any angle instantly. Includes Rolling Offsets, Simple Offsets, and Cutbacks.
CUSTOM FRACTION KEYPAD
We know you work in Imperial units. Our custom-built keypad features dedicated buttons for fractions (1/2, 3/4, 5/8, etc.), allowing you to input measurements and perform fractional math blazingly fast. No more converting to decimals.
MITERED BEND CALCULATOR
Just input your pipe diameter, bend radius, and number of welds. Get precise cut measurements instantly.
GLOVE-FRIENDLY AND DARK MODE
Designed with high-contrast UI and oversized buttons so you can use it perfectly even while wearing heavy work gloves in bright outdoor environments or dark trenches.
100 PERCENT OFFLINE CAPABILITY
No internet on the site? No problem. PipeFit Pro works entirely offline.
Work smarter, not harder. Upgrade your toolbox with PipeFit Pro today and make every cut perfect.
NEW — a different fitting on each end of a spool
Spool Cut now takes a 90 on one end and a 45 on the other. One pass, one cut length. Each end's take-out is listed separately, with the source of the number beside it. Thanks to the fitter who wrote in and asked for this.
FIXED — accuracy
• Switching between Imperial and Metric now converts what you entered. Before, your numbers were re-read under the new unit, so a measurement could change meaning when you flipped the toggle.
• Deg ↔ mm/m reported the wrong slope in Metric.
• The Rolling Offset diagram labelled the hypotenuse "Travel". That side is the True Offset — Travel lies in another plane.
• Short Radius is offered only on sizes ASME B16.28 actually covers (NPS 1"–24"). Sizes outside the standard no longer show an SR take-out.
• Take-out now always states where the number came from: a tabulated ASME value, or a calculated approximation for angles the standard does not tabulate.
If you saved work in Metric before this update, it is worth checking it again.
IMPROVED
• Angle marks on the Miter Cut, Segment Elbow and Weld Prep drawings now show what they are measured from.
• Bolt numbers on the flange pattern are readable on every pressure class.
• The Saved list shows every calculator type, not just the offsets.
• The About screen reports the real app version.
