Single Pipe Offsets

Notes:


The formulas are to be used in the solution of all single pipe offsets from 5 5/8° to 72° when you know the angle fitting to be used. There are six formulas involving relations between the set, the advance and the travel. Sample problems are given.

The tables and formulas are to be used when you want to make an offset but do not know what angle fitting to use.
