Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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; and an outer wrap applied to the outer wall, wherein: the outer wrap comprises fibers and plastic, and the outer wrap spans the corrugation crests producing a smooth outer surface. 2. The pipe of claim 1 , wherein the fiber comprises continuous strand fiberglass. 3. The pipe of claim 1 , wherein the fiber comprises continuous strand carbon fiber. 4. The pipe of claim 1 , wherein the fiber comprises short strands of fiberglass. 5. The pipe of claim 4 , wherein the short strands of fiberglass are semi-oriented circumferentially to the pipe. 6. The pipe of claim 1 , wherein the plastic of the outer wrap is fused to the outwardly extending corrugation crests. 7. A pipe comprising: an axially extended bore defined by a corrugated outer wall, wherein the outer wall comprises plastic, and the corrugated outer wall has an axial cross-section that is continuous; and an outer wrap applied to the outer wall, wherein: the outer wrap comprises plastic, and the outer wrap is applied in an overlapping helical pattern completely covering the outer wall. 8. The pipe of claim 7 , wherein the plastic of the bore and the plastic of the outer wrap are different types of plastic. 9. The pipe of claim 7 , wherein the plastic of the outer wall and the plastic of the outer wrap are welded together. 10. The pipe of claim 1 , wherein the corrugation crests and the corrugation valleys form annular corrugations. 11. The pipe of claim 7 , wherein the corrugated outer wall is made of annular corrugations.
