A drainage pipe is defined as a structure (other than a bridge) to convey water through a trench or under a fill or some other obstruction. Materials for permanent-type installations include non-reinforced concrete, reinforced concrete, corrugated steel, plastic, corrugated aluminum alloy, and structural plate steel pipe. 9-1.1 Pipe Selection

The coating breakdown factors as shown in table 5.2 apply equally to both buried and non-buried pipelines. It is assumed that coatings and field joint systems have been chosen to be compatible with the maximum design temperature of the pipeline. For pipelines with the following coating systems, another coating breakdown factor is calculated.

STRUCTURAL DESIGN OF BURIED FLEXIBLE PIPES FOR TRENCHLESS

Trenchless pipe installation methods are many and varied in terms of how pipe is installed. From the perspective of the structural design of the pipe for permanent design loads, how the pipe is installed is less important than what the installed pipe looks like in relation to the existing material in which it was installed.
