Abstract

A jumper tube for use with a shunt tube assembly comprises a first tubular member configured to engage a first shunt tube, a second tubular member axially disposed within the first tubular member, and a locking member configured to prevent the second tubular member from axially displacing into the first tubular member. The second tubular member is configured to slidingly engage within the first tubular member, and the second tubular member is configured to engage a second shunt tube.

First claim

What is claimed is:

1. A shunt tube assembly to be mounted alongside a base pipe assembly, the shunt tube assembly comprising:
a first shunt tube having a first end;
a second shunt tube having a first end; and
a jumper tube assembly fluidly connecting the first shunt tube and the second shunt tube, wherein the jumper tube assembly comprises:
a first tubular member engaged with the first end of the first shunt tube;
a second tubular member disposed within the first tubular member, wherein the second tubular member telescopically and slidingly engages within the first tubular member, and wherein the second tubular member is extended to engage with the first end of the second shunt tube; and
a locking member that engages the first tubular member and the second tubular member, and wherein the locking member prevents the second tubular member from telescopically and longitudinally displacing further into the first tubular member when the locking member engages both the first tubular member and the second tubular member.

2. The shunt tube assembly of claim 1 , wherein the locking member is engaged with at least a portion of an outer surface of the second tubular member.

3. The shunt tube assembly of claim 1 , wherein the locking member is engaged with an inner surface of the first tubular member.

4. The shunt tube assembly of claim 1 , wherein the locking member maintains engagement between the jumper tube assembly and the shunt tube assembly.

5. The shunt tube assembly of claim 1 , wherein the locking member maintains a sealing engagement between the jumper tube assembly and the shunt tube assembly.

6. The shunt tube assembly of claim 1 , wherein the locking member comprises frictional grooves on at least one face, and wherein the frictional grooves prevent longitudinal movement of the locking member along a longitudinal axis of the jumper tube assembly.

7. The shunt tube assembly of claim 1 , wherein the second tubular member comprises grooves disposed on an outer surface of the second tubular member, and wherein the grooves prevent longitudinal movement of the locking member along a longitudinal axis of the second tubular member.

8. The shunt tube assembly of claim 1 , further comprising at least one seal disposed between the first tubular member and the second tubular member, wherein the at least one seal sealingly engages the first tubular member and the second tubular member.

9. The shunt tube assembly of claim 1 , wherein the first tubular member engages at least a portion of the locking member.

10. The shunt tube assembly of claim 1 , wherein a portion of the locking member is disposed between an inner surface of the first tubular member and an outer surface of the second tubular member.

11. The shunt tube assembly of claim 1 , wherein the first tubular member comprises frictional grooves disposed on an inner surface of the first tubular member, and wherein the frictional grooves prevent longitudinal movement of the locking member along a longitudinal axis of the first tubular member.

12. The shunt tube assembly of claim 1 , wherein the locking member comprises a c-ring, wherein the c-ring comprises frictional grooves disposed on an inner surface, and wherein the frictional grooves prevent longitudinal movement of the locking member along a longitudinal axis of the first tubular member.

13. The jumper tube assembly of claim 12 , wherein the second tubular member comprises frictional grooves disposed on an outer surface, wherein the c-ring is disposed about the second tubular member, and wherein the frictional grooves disposed on the inner surface of the c-ring engage the frictional grooves disposed on the outer surface of the second tubular member.

14. A jumper tube assembly for use with a shunt tube assembly comprising:
a first tubular member capable of engaging a first end of a first shunt tube;
a second tubular member axially disposed within the first tubular member, wherein the second tubular member is capable of extending into engagement with a first end of a second shunt tube, wherein the second tubular member has an outer surface in contact with the inner surface of the first tubular member, and wherein the second tubular member comprises circumferential grooves disposed on the outer surface of the second tubular member;
a locking member engaging the outer surface of the second tubular member, the locking member comprising circumferential grooves on an inner surface, and wherein the circumferential grooves of the second tubular member interact with the circumferential grooves of the locking member to prevent further longitudinal movement of the second tubular member into the first tubular member.

15. The jumper tube assembly of claim 14 , wherein the locking member comprises a c-ring.

16. The jumper tube assembly of claim 14 , wherein the locking member engages the first tubular member and the second tubular member.
