Abstract
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.
Claims19
A pipe, comprising:
- an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests connected by corrugation valleys, the corrugation crests and valleys forming a continuous cross-section;
