Abstract

A disclosed pipe scuffing device includes a frame and a shaft coupled to the frame and configured to rotate about a central axis. The pipe scuffing device also includes a drive motor configured to drive the rotation of the shaft. The device further includes one or more abrasive wheels disposed about the shaft and having an abrasive outer surface configured to engage an outer surface of a pipe when rotating with the shaft to remove one or more contaminants from the outer surface of the pipe.

First claim

What is claimed is:

1. A pipe processing system, comprising:
a pipe scuffing system, comprising:
a pipe scuffing device comprising an abrasive wheel assembly including one or more abrasive wheels having an abrasive surface and being configured to contact an outer surface of a pipe; and
a control system configured to control the pipe scuffing device to selectively engage and disengage the one or more abrasive wheels with the outer surface of the pipe;
a pipe positioning system comprising a support configured to support the pipe; and
wherein the pipe scuffing device further comprises a frame configured to support the abrasive wheel assembly and to couple to the support such that the abrasive wheel assembly is configured to ascend and descend along a vertical length of the frame to engage and disengage with the pipe.

2. The pipe processing system of claim 1 , wherein the pipe positioning system comprises a drive mechanism configured to alter a relative position between the pipe and the one or more abrasive wheels by driving movement of the support.

3. The pipe processing system of claim 2 , wherein the drive mechanism is configured to drive movement of the support such that a spin direction of the pipe is counter to a spin direction of the one or more abrasive wheels.

4. The pipe processing system of claim 1 , further comprising a pipe wrapping system configured to receive the pipe after the pipe is scuffed by the pipe scuffing device and to add an additional layer of material to the pipe.

5. The pipe processing system of claim 1 , wherein at least one processor of the control system is configured to control the one or more abrasive wheels to rotate in a direction counter to a rotation direction of the pipe.

6. The pipe processing system of claim 1 , wherein the one or more abrasive wheels comprise one or more flap wheels or one or more wire wheels.

7. The pipe processing system of claim 1 , wherein a ratio of a width of each of the one or more abrasive wheels to a pitch of corrugations in the pipe is between ⅓ and ⅙.

8. The pipe processing system of claim 1 , wherein the pipe scuffing device further comprises a guide roller configured to engage with the pipe when the one or more flap wheels engage with the pipe at a distance that determines a depth of a scuff of the pipe.

9. A pipe scuffing device, comprising:
a frame;
a shaft coupled to the frame and configured to rotate about a central axis;
a drive motor configured to drive the rotation of the shaft;
one or more abrasive wheels disposed about the shaft and comprising an abrasive outer surface configured to engage an outer surface of a pipe when rotating with the shaft to remove one or more contaminants from the outer surface of the pipe; and
a guide roller coupled to the frame and configured to engage the pipe when the one or more abrasive wheels engage the pipe to determine a depth of scuffing of the pipe.

10. The pipe scuffing device of claim 9 , wherein a ratio between a width of each of the one or more abrasive wheels and a pitch of corrugations in the pipe is between ⅓ and ⅙.

11. The pipe scuffing device of claim 9 , wherein the frame further comprises a pulley arm coupled to the drive motor and to the shaft and configured to alter a position of the shaft between a disengaged position and an engaged position with respect to the pipe.

12. The pipe scuffing device of claim 9 , wherein the frame further comprises one or more tracks configured to enable translational movement of the shaft and one or more abrasive wheels along the length of the one or more tracks.

13. The pipe scuffing device of claim 12 , wherein the one or more tracks are disposed on a bracket of the frame configured to couple to a support for supporting the pipe.

14. The pipe scuffing device of claim 9 , wherein the one or more abrasive wheels are one or more flap wheels or one or more wire wheels.

15. The pipe scuffing device of claim 9 , wherein the one or more abrasive wheels comprises a plurality of flap wheels, and each of the plurality of flap wheels is separated by a uniform distance.

16. A pipe scuffing system, comprising:
a corrugated pipe having a pitch defined by one or more corrugations disposed along a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys; and
a pipe scuffing device comprising a plurality of abrasive wheels each having an abrasive surface, wherein a ratio of a width of each of the plurality of flap wheels to the pitch of the corrugated pipe is between ⅓ and ⅙.

17. The pipe scuffing system of claim 16 , further comprising a control system comprising at least one processor configured to control the pipe scuffing device to rotate the plurality of abrasive wheels in a direction counter to a rotation direction of the corrugated pipe.
