FitUp: Pipe Offset Calculator

The cut length for your offset, take-outs and gap already off, so you cut it once. Most offsets still get worked out on a piece of cardboard: offset times 1.414, minus two take-outs, minus two gaps, then turn 11.14 into a mark on the tape and hope the cut is right. FitUp does that math the same way every time. Type the offset, pick the angle, the pipe size, and the fitting, and read the cut length to the nearest 1/16 inch, with the travel, the run, and each allowance listed under it and the formula on screen so you can check it. SIMPLE OFFSETS, ANSWERED AS A CUT Enter the offset center to center. FitUp returns the travel (the offset divided by the sine of the angle), the run, the take-out for each fitting, the gap for each joint, and the cut length. The offset triangle is drawn and labeled, and the formula line shows the multipliers, 1.414 and 1.000 for a 45. Offsets at 45 degrees are free and unlimited. Pick 11.25°, 22.5°, 30°, 60°, or a custom angle from 1 to 89 degrees and the diagram draws for it right away; Pro shows the travel, run, and cut length for every one of them, using a 90 elbow cut down to that angle. Pick no fittings for center to center. ROLLING OFFSETS FROM RISE AND ROLL Type the rise and the roll. FitUp works out the true offset (the square root of rise squared plus roll squared), then the travel, run, and cut length at your angle, and draws the box the pipe runs through. Ten rolling offsets at 45 degrees are free each month; the count left sits next to the tool. Pro removes the limit and adds setback mode: type the run you have, and FitUp solves the fitting angle. TAKE-OUTS FROM 1/2 TO 12 INCH The take-out chart lists center-to-end values for 90 long radius, 45 long radius, and 90 short radius (1 inch and up) butt-weld elbows from 1/2 to 12 inch pipe. They are marked as defaults, because fittings vary by maker. The 1/2, 3/4, and 1 inch rows are free to read. Pro opens every size, lets you edit any value or type in threaded and socket-weld take-outs, and sets the weld gap per joint (1/8 inch by default for welded trades). JOBS AND CUT LISTS The offset you try during setup is already saved as the first cut of Job 1. Save each calculation to a job, and the cuts stack up as a cut list you can read at the saw. One job with any number of cuts is free. Pro keeps a job for every site and sends a cut list as text or as an image to the foreman or the shop. FRACTIONS YOUR TAPE CAN READ Answers come out in fractional inches rounded once to the nearest 1/16, or in decimal inches to three places, with the exact decimal in the formula line. Pro adds 1/32 rounding and millimeters. WHAT IS FREE Unlimited 45 degree simple offsets with the full answer, diagram, and formula. Ten rolling offsets at 45 degrees every month. The take-out chart for 1/2, 3/4, and 1 inch. One saved job with any number of cuts. Fractions to the 1/16, or decimals. No account and no ads, and your jobs stay on your iPhone. CHECK BEFORE YOU CUT FitUp is a layout calculator. It does not inspect fittings or check code. Verify measurements and fitting dimensions before cutting.
