Abstract

The disclosure relates to a tool for honing a tubular component of a wellsite. The honing tool includes a base operatively connectable to a wellsite component, a honing head supported by the base, honing stones supported about the honing head, and a driver. The honing stones are engageable with an outer surface of the tubular component. The driver rotationally drives the honing head whereby the honing stones hone an outer periphery of the tubular component.

First claim

What is claimed is:

1. A tool for honing a tubular component of a wellsite, the honing tool comprising:
a base operatively connectable to a flange of a wellsite component, wherein the wellsite component is configured to receive at least a portion of the tubular component through a tubular component hole disposed through the flange of the wellsite component;
a honing head supported by the base and positionable about the tubular component;
honing stones supported about the honing head, the honing stones engageable with an outer surface of a portion of the tubular component extending from the tubular component hole; and
a driver to rotationally drive the honing head whereby the honing stones hone an outer periphery of the tubular component.

2. The honing tool of claim 1 , further comprising a mounting plate configured to operatively connect the base to the flange of the wellsite component.

3. The honing tool of claim 2 , further comprising a bracket supported on a surface of the mounting plate and configured to operatively connect the base to the mounting plate.

4. The honing tool of claim 1 , wherein the driver axially drives the honing head.

5. The honing tool of claim 1 , wherein the honing head has tubular body with a stop plate at an end thereof, the honing head having a cavity to receive the tubular component therein.

6. The honing tool of claim 1 , wherein the honing stones are positioned about an inner surface of the honing head.

7. The honing tool of claim 6 , wherein the honing stones comprise three honing stones spaced equally about an inner periphery of the honing head.

8. The honing tool of claim 1 , further comprising supports to support the honing stones in the honing head.

9. The honing tool of claim 8 , wherein the supports comprise at least one of a platform, a rod, a spring, a collar, and an adjustment screw.

10. The honing tool of claim 1 , further comprising a stop positionable in the honing head, the stop comprising a wear disk engageable by the tubular component.

11. The honing tool of claim 1 , wherein the wellsite component is at least one of a tubing, a riser, a flange, a workbench, and a combination thereof.

12. The honing tool of claim 11 , wherein the tubular component comprises at least one pin of a riser.

13. An assembly for honing a tubular component of a wellsite, the honing assembly comprising:
a honing tool, comprising:
a base operatively connectable to a flange of a wellsite component via a mount, wherein the wellsite component is configured to receive at least a portion of the tubular component through a tubular component hole disposed through the flange of the wellsite component;
a honing head supported by the base and positionable about the tubular component;
honing stones supported about the honing head, the honing stones engageable with an outer surface of a portion of the tubular component extending from the tubular component hole; and
a driver to rotationally drive the honing head whereby the honing stones hone an outer periphery of the tubular component.

14. The honing assembly of claim 13 , further comprising connectors to secure the base to the mount.

15. The honing assembly of claim 13 , wherein the mount comprises a mounting plate.

16. The honing assembly of claim 13 , wherein the mount comprises a mounting wheel.

17. The honing assembly of claim 13 , wherein the mount further comprises clamps.

18. The honing assembly of claim 13 , wherein the mount further comprises handles.

19. The honing assembly of claim 13 , further comprising an adjuster adjustably connecting the base to the mounting plate.

20. The honing assembly of claim 19 , wherein the mount has slots therein and the adjuster comprises a bracket slidably movable about the slots.

21. The honing assembly of claim 19 , wherein the adjuster comprises a plate operatively connectable to the base and rods slidably extendable therefrom, the rods operatively connectable to the mount.

22. The honing assembly of claim 13 , further comprising a fluid source extending into the honing head.

23. The honing assembly of claim 13 , further comprising a centering jig positionable in the honing head, the centering jig having inlets defining a position of the honing stones in the honing head.

24. A method of honing a tubular component of a wellsite, the method comprising:
providing a honing tool comprising a base and a honing head;
adjustably positioning honing stones in the honing head;
mounting the honing tool to a flange of a wellsite component, wherein the wellsite component is configured to receive at least a portion of the tubular component through a tubular component hole disposed through the flange of the wellsite component;
disposing the honing head about an outer surface of a portion of the tubular component extending from the tubular component hole; and
rotating the honing head.

25. The method claim 24 , further comprising axially moving the honing head along the tubular component.

26. The method claim 24 , wherein the mounting comprises operatively connecting the base to a flange of the wellsite component via a mounting plate and an adjuster.

27. The method of claim 24 , wherein the disposing comprises centering the honing stones about an inner periphery of the honing head.

28. The method of claim 24 , wherein the disposing comprises adjustably positioning the honing stones in the honing head.

29. The method of claim 24 , wherein the disposing comprises springingly supporting the honing stones about an inner periphery of the honing head.

30. The method of claim 24 , further comprising axially moving the honing head about the tubular component.

31. The method of claim 30 , further comprising terminating the axially moving with a stop.
