ABSTRACT
The decision to bury a pipe or place it above ground depends on several factors: on one hand, a buried pipe (a) reduces plant congestion, (b) allows for the shortest route (fewer bends) from point to point, (c) avoids existing above ground obstructions, (d) is protected from ambient temperature changes, (e) is protected from wind loads, and (f) if buried deeply, is protected from surface traffic and activities. In certain cases, burying the pipe may be the only viable alternative.
