1. A spoolable tube for enhanced internal fluid flow, comprising: a substantially low axial strength inner layer of unitary construction comprising a plurality of channels for transporting fluid and resisting leakage of internal fluids, wherein the plurality of channels are formed by multi-cell extrusion, and wherein said low axial strength inner layer comprises a polymer selected from at least one of a thermoplastic polymer, a thermoset polymer and an elastomer; andan outer reinforcing layer substantially surrounding the inner layer comprising fibers and a matrix, wherein the fibers comprise at least one of a glass, an aramid, a carbon, a metal, and a polymer. 2. The spoolable tube of claim 1, wherein a pressure within the tube is substantially maintained by the outer reinforcing layer. 3. The spoolable tube of claim 2, wherein a pressure differential between said channels is not greater than about 100 psi. 4. The spoolable tube of claim 1, wherein said polymer comprises at least one of: polyethylene, polyamide and polypropylene. 5. The spoolable tube of claim 1, wherein said channels have circular, oval, rectangular, square, or polygonal cross-sectional shape. 6. The spoolable tube of claim 1, wherein said fibers are helically wound about the axis of said tube. 7. The spoolable tube of claim 1, wherein the fibers are cross-plied with an orientation of about ±40° to about ±70° about the axis of said tube. 8. The tube of claim 1, further comprising a sensor. 9. The tube of claim 1, further comprising an energy conductor or a data conductor that extends along the length of the tube. 10. The tube of claim 1, further comprising electrical power conductors. 11. The tube of claim 1, further comprising axial reinforcement external to said inner layer. 12. A method of transporting a multi-phase fluid comprising: providing a spoolable pipe of claim 1;introducing a multi-phase fluid into an inlet of the spoolable pipe such that the multiphase fluid can travel along the plurality of the channels; andrecombining the fluid at an outlet of the spoolable pipe, and therefore providing substantially continuous constant flow of all phases of the multi-phase fluid. 13. The tube of claim 1, wherein the channels provide the only paths for fluid transport within the tube. 14. A method for forming a spoolable pipe capable of transporting multi-phase fluid comprising: extruding a thermoplastic polymer to form a unitary inner layer comprising a plurality of channels for transporting fluid and resisting leakage of internal fluids, wherein the plurality of channels are formed by multi-cell extrusion, and wherein said low axial strength inner layer comprises a polymer selected from at least one of a thermoplastic polymer, a thermoset polymer and an elastomer; andforming a reinforcing layer comprising fibers and a matrix over the inner layer to form a spoolable pipe, wherein the fibers comprise at least one of a glass, an aramid, a carbon, a metal, and a polymer. 15. The method of claim 14, wherein the forming a reinforcing layer comprises helically winding fibers around the inner layer. 16. The method of claim 15, wherein the forming a reinforcing layer further comprises applying a matrix.
