Abstract

A support ring for a tubular connection is provided that comprises a body comprising a first end and a second end. A circumferential ring lip extends from the first end of the body and positioned perpendicular to the body. A protrusion is positioned on the body between the first end and the second end. The protrusion comprises a top surface and a bottom surface.

Claims

1. A support ring for a tubular connection, comprising:

a body comprising a first end and a second end;

a circumferential ring lip positioned proximate to, and extending substantially perpendicular from, the first end of the body; and

a protrusion positioned on the body between the first end and the second end, wherein the protrusion comprises a top surface and a bottom surface.

2. The support ring according to claim 1, wherein the top surface of the protrusion is angled relative to the body.

3. The support ring according to claim 1, wherein the bottom surface of the protrusion is aligned with the second end of the body and the top surface of the protrusion is positioned between the first end of the body and the second end of the body.

4. The support ring according to claim 1, wherein the protrusion comprises a protrusion threading configured to mate with a socket threading of a connection socket.

5. The support ring according to claim 1, further comprising:

a compressible split extending from the first end of the body to the second end of the body.

6. A support ring for a tubular connection, comprising:

a body comprising an outer surface, a first end, and a second end;

a protrusion axially positioned on the body, comprising a top surface and a bottom surface and extending circumferentially from the body; and

a circumferential ring lip extending from the first end of the body.

7. The support ring according to claim 6, wherein the protrusion is axially spaced from the first end of the body and the second end of the body.

8. The support ring according to claim 6, further comprising:

a compressible split extending from the first end of the body to the second end of the body.

9. The support ring according to claim 6, wherein an inner surface of the body is configured to increase drag against a pipe.

10. The support ring according to claim 6, wherein the top surface and the bottom surface of the protrusion are substantially perpendicular relative to the body of the support ring.

11. A tubular connection, comprising:

a connection socket comprising an outer lip and a socket cup;

a pipe comprising a pipe end in contact with the socket cup; and

a support ring positioned about the pipe and operably coupled to the connection socket, wherein the support ring comprises;

a body having an outer surface, a first end, and a second end;

a ring lip extending from the first end of the body and positioned substantially flush with the outer lip of the connection socket; and

a protrusion having a top surface and a bottom surface, wherein the protrusion is positioned on the body of the support ring.

12. The tubular connection of claim 11, wherein the connection socket comprises a sealing recess, and further wherein the second end of the body of the support ring is positioned in contact with the sealing recess.

13. The tubular connection of claim 11, wherein the protrusion of the support ring comprises a protrusion threading that is mated with a socket threading of the socket cup.

14. The tubular connection of claim 11, wherein the socket cup comprises an inner surface, and further wherein the inner surface defines a channel.

15. The tubular connection of claim 14, wherein the channel is in contact with the protrusion.

16. The tubular connection of claim 11, wherein the support ring defines a compressible split extending from the first end of the body to the second end of the body.

17. The tubular connection of claim 11, wherein the second end of the body is positioned beneath a pressing point on the connection socket.

18. The tubular connection of claim 11, wherein the top surface of the protrusion is angled relative to the body.

19. The tubular connection of claim 11, wherein the bottom surface of the protrusion is aligned with the second end of the body and the top surface of the protrusion is positioned between the first end of the body and the second end of the body.

20. The tubular connection of claim 11, wherein the protrusion is axially spaced from the first end of the body and the second end of the body.
