Abstract

This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with a reinforcing stiffener. The corrugated pipe may include an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. In some embodiments, a stiffener may be positioned within the corrugation valleys. In other embodiments, a stiffener may be positioned within the corrugation crests.
