This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.

A method of automated pipeline chemical batch treatment includes receiving treatment information at a control system of a pipeline. If the treatment information includes an instruction to activate a pump system, the method includes transmitting an activation signal from the control system to the pump system in accordance with the treatment information. The activation signal causes the pump system to pump one or more chemicals from a chemical feed system into the pipeline. If the treatment information includes an instruction to deactivate the pump system, the method includes transmitting a deactivation signal from the control system to the pump system in accordance with the treatment information, wherein the deactivation signal causes the pump system to stop pumping one or more chemicals from the chemical feed system into the pipeline.
