Pipepro Pipefitting Calculator solves piping offsets of any angle fitting to a piping cut length with input to any 2 of the 4 possible offset variables: set, run, travel, and fitting angle. For example, instead of inputting 12 inches for set and 45 for angle of fitting, you could input travel length and run to solve for fitting angle and set.
