Pipe with an outer wrap
The embodiments of the present disclosure provide a method of applying an outer wrap to a corrugated pipe. The method comprises receiving a corrugated pipe that is cut to length, determining a wrap type to be applied to the corrugated pipe, determining a flow rate for applying a wrap of the wrap type based on a type of plastic used in the wrap, a type of fiber used in the wrap, and the wrap type, and applying a wrap made of the type of fiber and the type of plastic to the corrugated pipe using the determined flow rate.
1. A method of applying an outer wrap to a corrugated pipe comprising:
receiving a corrugated pipe that is cut to length;
determining a wrap type to be applied to the corrugated pipe;
determining a flow rate for applying a wrap of the wrap type based on a type of plastic used in the wrap, a type of fiber used in the wrap, and the wrap type;
extruding the type of plastic at the determined flow rate; and
applying a wrap made of the type of fiber and the type of plastic to the corrugated pipe using the determined flow rate, wherein applying the wrap includes pulling the wrap at a predetermined ratio relative to the determined flow rate.
2. The method of claim 1 , wherein the type of fiber comprises continuous strand fiber.
3. The method of claim 1 , wherein the type of fiber comprises short strands of fiber having a length ranging from about 0.25 inches to about 1 inch.
4. The method of claim 1 , wherein the wrap type is determined based on a required strength and a type of available fiber.
5. The method of claim 1 , wherein the wrap type includes one or more of: oriented continuous strand fiber, semi-oriented non-continuous fiber, or fiberglass impregnation.
6. The method of claim 1 , further comprising:
heating the type of plastic used in the wrap to a predetermined temperature.
7. The method of claim 6 , wherein the determined flow rate ranges from 15 to 25 feet per minute.
8. The method of claim 1 , wherein the corrugated pipe comprises:
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.
9. The method of claim 8 , wherein applying the wrap further comprises applying the wrap to span the corrugation crests.
10. The method of claim 1 , wherein the corrugated pipe comprises:
an axially extended bore defined by a corrugated outer wall, wherein the corrugated outer wall comprises plastic, and the corrugated outer wall has an axial cross-section that is continuous.
11. The method of claim 10 , wherein applying the wrap further comprises applying the wrap in an overlapping helical pattern to completely cover the outer wall of the corrugated pipe.
12. A method of applying an outer wrap to a corrugated pipe comprising:
receiving an uncut corrugated pipe from a pipe extrusion device;
determining a wrap type to apply to the uncut corrugated pipe;
determining a flow rate for applying a wrap of the wrap type based on a type of plastic used in the wrap, a type of fiber used in the wrap, and the wrap type;
extruding the type of plastic at the determined flow rate; and
applying a wrap made of the type of fiber and the type of plastic to the corrugated pipe using the determined flow rate, wherein applying the wrap includes pulling the wrap at a predetermined ratio relative to the determined flow rate.
13. The method of claim 12 , wherein the type of fiber comprises continuous strand fiber.
14. The method of claim 12 , wherein the type of fiber comprises short strands of fiber having a length ranging from about 0.25 inches to about 1 inch.
15. The method of claim 12 , wherein the wrap type is determined based on a required strength and a type of available fiber.
16. The method of claim 12 , wherein the wrap type includes one or more of: oriented continuous strand fiber, semi-oriented non-continuous fiber, or fiberglass impregnation.
17. The method of claim 12 , wherein applying the wrap comprises:
applying the wrap from a rotating wrap extrusion device that circumscribes an outer surface of the uncut corrugated pipe with the wrap.
18. The method of claim 17 , wherein the rotating wrap extrusion device pulls the wrap by rotating at a velocity that is greater than the flow rate based on the predetermined ratio relative to the flow rate.
19. The method of claim 12 , further comprising:
heating the type of plastic used in the wrap to a predetermined temperature.
20. The method of claim 19 , wherein the determined flow rate ranges from 15 to 25 feet per minute.
21. The method of claim 12 , wherein the corrugated pipe comprises:
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.
22. The method of claim 21 , wherein applying the wrap further comprises applying the wrap to span the corrugation crests.
23. The method of claim 12 , wherein the corrugated pipe comprises:
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.
24. The method of claim 23 , wherein applying the wrap further comprises applying the wrap in an overlapping helical pattern to completely cover the outer wall of the corrugated pipe.
