Pipes with non-dimensional diameter larger than 40 are considered large diameter pipes because Taylor bubbles occupying the entire pipe cross section can no longer be sustained. The intervening range, from non-dimensional diameter of 18.5–40, is a transition region between the two behaviors [ 37 ].

Large diameter pipes tend to fail predominantly by longitudinal fracture. The failure mechanisms involving longitudinal fractures indicated that a large corrosion patch …
For years, the large diameter (defined as 16 in. and above) water pipe market has been represented in the United States by steel pipe (SP), precast concrete cylinder pipe (PCCP), ductile iron pipe (DIP), and PVC (polyvinyl chloride) pipe. HDPE pipe, on the other hand, comprises just 2 to 5% of the large diameter water pipe market.

The findings reveal that wire breakage has a limited influence on the pipe's force distribution, showing little changes in the force state within 1/3 of the pipe's length at both ends. The broken wire threshold increases with the steel wire area for pipes with an inside diameter of 1400 mm, although the increasing trend slows down.

While large utility drills can be efficient on many intermediate projects, pilot bores at longer distances and in challenging ground conditions require larger-diameter drill pipe to deliver higher volumes of drilling fluid. Larger pipe requires greater torque to make and break connections, which means stepping up to a larger drill.
@justinj I agree. The larger volume of the pipe in the middle is likely to have roughly the same effect as making a smaller pipe longer. Either way, you have to push more water volume to get water to the far end, so if you're pushing hot water, you're going to have to push more cold water out of the way to get the hot water to the other end.
