1. A tube assembly comprising: a first tube having a radial exterior surface;a second tube composed of a plurality of segments, the first tube co-axially nested within the second tube;at least a first spacer coupled to the first tube; anda second spacer coupled to the at least a first spacer,wherein a first segment of the plurality of segments is coupled to a first axial end of the second spacer,wherein a second segment of the plurality of segments is coupled to a second axial end of the second spacer,wherein the at least a first spacer includes a first inner spacer and a second inner spacer, andwherein a first center of the first inner spacer is aligned with a second center of the second inner spacer relative to an axial length of the first tube. 2. The tube assembly of claim 1, further comprising: an end fitting coupled to the first tube. 3. The tube assembly of claim 2, wherein the second tube is coupled to the end fitting. 4. The tube assembly of claim 1, further comprising: a first ferrule coupled to the first tube. 5. The tube assembly of claim 4, further comprising: a second ferrule coupled to the second tube. 6. The tube assembly of claim 5, wherein a third segment of the plurality of segments is coupled to the second ferrule. 7. The tube assembly of claim 1, wherein the first center and the second center are separated from one another by approximately one-hundred eighty degrees relative to a circumference of the first tube. 8. The tube assembly of claim 1, wherein a first structure of the first inner spacer is separated from a second structure of the second inner spacer by a non-zero value of distance. 9. The tube assembly of claim 1, wherein the first tube is configured to convey a fluid. 10. The tube assembly of claim 9, wherein the fluid includes at least one of oil, fuel, hydraulic fluid, or air. 11. The tube assembly of claim 9, wherein the second tube is configured to convey a second fluid. 12. The tube assembly of claim 1, wherein the tube assembly is mounted to an engine of an aircraft. 13. A method comprising: sliding a plurality of outer tube segments onto an inner tube;using an outer spacer to separate a first and a second of the plurality of outer tube segments;attaching at least one inner spacer to the inner tube;attaching the outer spacer to the at least one inner spacer;attaching the outer spacer to the first outer tube segment; andattaching the outer spacer to the second outer tube segment,wherein the at least one inner spacer includes a first inner spacer and a second inner spacer, andwherein a first center of the first inner spacer is aligned with a second center of the second inner spacer relative to an axial length of the inner tube. 14. The method of claim 13, further comprising: attaching the inner tube to an end fitting. 15. The method of claim 14, further comprising: attaching the first outer tube segment to the end fitting. 16. The method of claim 13, further comprising: attaching an inner ferrule to the inner tube. 17. The method of claim 16, further comprising: attaching an outer ferrule to the second outer tube segment. 18. The method of claim 16, further comprising: attaching an outer ferrule to a third outer tube segment of the plurality of outer tube segments. 19. A tube assembly comprising: a first tube having a radial exterior surface;a second tube composed of a plurality of segments, the first tube co-axially nested within the second tube;at least a first spacer coupled to the first tube; anda second spacer coupled to the at least a first spacer,wherein a first segment of the plurality of segments is coupled to a first axial end of the second spacer,wherein a second segment of the plurality of segments is coupled to a second axial end of the second spacer,wherein the at least a first spacer includes a first inner spacer and a second inner spacer, andwherein a first structure of the first inner spacer is separated from a second structure of the second inner spacer by a non-zero value of distance.
