Pipe Offset Travel Calculator

Work out the travel, run and shrink of a pipe offset in seconds. Enter the offset between the pipe centerlines and the fitting angle, subtract the take-outs, and get the length to cut, with a labeled diagram that shows where each value comes from. Key features - Simple and rolling offsets: enter the offset between pipe centerlines, or rise and roll for a rolling offset to get the true offset. - Standard fitting angles: 22.5°, 30°, 45° and 60° in one tap, plus any angle from 5° to 85°. - Travel, run and shrink: center-to-center travel, run, shrink and the multiplier, drawn on a diagram. - Take-outs and cut length: subtract the take-out at each end to get the length of pipe to cut. - Inch fractions or millimeters: feet and inches rounded to 1/8, 1/16 or 1/32, decimal inches, or mm. - Compare and keep: see the same offset at every standard angle, reopen the last 10 calculations, and copy or share a text card. Made for - Pipefitters, plumbers, welders and fabricators who lay out offsets at the bench or on site. Results are geometric values from your inputs. Weld shrinkage, weld gaps and fitting catalogs are not included, and the app does not replace your drawings. Check dimensions before you cut.
