Minimum width recommendations are: 18 in. (450 mm) for 4- and 6-in. (100- and 150-mm) pipe sizes No less than 12 to 18 in. (300 to 450 mm) greater than the pipe OD for 8-in.

www.usbr.govIn addition to the initial out-of-roundness, placement and compaction of the soil beside the pipe can cause elongation (an increase in the vertical diameter) of the pipe. The elongation is dependent on the pipe stiffness, the type of compaction, the percent compaction, and whether or not the pipe is strutted [4].
