1. A system for conveying a fluid comprising: a spoolable tube comprising: an inner layer which defines a first passage for conveying a first fluid, wherein said inner layer comprises a first layer and a reinforcing layer comprising fiber;an outer layer;an annular space between said inner and said outer layer defining a second passage comprising a plurality of channels for conveying a second fluid, wherein the plurality of channels extend substantially along an axial length of the spoolable tube; and,a first fitting adapted to engage an axial end of said inner layer and a second fitting adapted to engage an axial end of said outer layer, wherein said first fitting comprises a first venting mechanism for venting at least part of the first fluid and a first seal adapted to reversibly seal said first passage directly from the atmosphere or separate containment device, and wherein said second fitting comprises a second venting mechanism for venting at least part of the second fluid and a second seal adapted to reversibly seal said second passage directly from the atmosphere or separate containment device. 2. The system of claim 1, wherein said first passage is capable of conveying said first fluid at a first pressure and wherein said second passage is capable of conveying said second fluid at a second pressure. 3. The system of claim 2, wherein said second pressure is less than or equal to said first pressure. 4. The system of claim 2, wherein said second fitting includes a means to measure said second pressure. 5. The system of claim 2, wherein said second fitting includes a means to limit said second pressure. 6. The system of claim 2, wherein said second pressure is less than said first pressure. 7. The system of claim 1, further comprising a relief valve. 8. The system of claim 1, wherein said first layer comprises one or more of a polymer, an elastomer, or a metal. 9. The system of claim 8, wherein said first layer comprises a thermoplastic. 10. The system of claim 8, wherein said first layer comprises high density polyethylene, crosslinked polyethylene, polyvinylidene fluoride, polyamide, polyethylene terphthalate, or polypropylene, and combinations thereof. 11. The system of claim 1, wherein said outer layer comprises one or more of a polymer, an elastomer, or a metal. 12. The system of claim 11, wherein said outer layer comprises a thermoplastic. 13. The system of claim 11, wherein said outer layer comprises high density polyethylene, crosslinked polyethylene, polyvinylidene fluoride, polyamide, polyethylene terphthalate, or polypropylene, and combinations thereof. 14. The system of claim 1, wherein said fiber comprises one or more of a glass, an aramid, a metal, a carbon, a ceramic, or a mineral. 15. The system of claim 1, wherein said reinforcing layer further comprises a matrix. 16. The system of claim 15, wherein said fibers are embedded in said matrix. 17. The system of claim 15, wherein said matrix comprises an epoxy. 18. The system of claim 15, wherein said matrix comprises a polymer. 19. The system of claim 18, wherein said polymer comprises a thermoplastic polymer. 20. The system of claim 1, wherein said fibers are encapsulated by a polymer. 21. The system of claim 1, wherein said fibers further comprise a coating. 22. The system of claim 1, wherein said reinforcing layer further comprises an energy conductor or a data conductor. 23. The system of claim 1, further comprising an energy conductor disposed between the inner layer and the outer layer. 24. The system of claim 1, wherein at least one of said first and second fittings include a connection for an energy conductor or a data conductor. 25. The system of claim 24, wherein said energy conductor comprises at least one of: a fiber optic cable, a fiber optic sensor, a metal, or an insulated metal. 26. The system of claim 1, further comprising a physical perturbation disposed between said inner layer and said outer layer. 27. The system of claim 26, wherein said physical perturbation forms said second passage for conveying said second fluid. 28. The system of claim 27, wherein an outer surface of the reinforcing layer comprises said physical perturbation. 29. The system of claim 27, wherein said physical perturbation is axially or helically oriented. 30. The system of claim 28, wherein said physical perturbation comprises a multi-filament yarn. 31. The system of claim 1, wherein said outer layer is of unitary construction. 32. The system of claim 1, wherein said second passage comprises channels or grooves. 33. The system of claim 1, wherein an outer surface of said inner layer comprises a physical perturbation forming said annular space. 34. The system of claim 33, wherein said physical perturbation is a channel, groove, cleft, ridge, bump or post. 35. The system of claim 34, wherein said physical perturbation is discontinuous along the axial length of the tube. 36. The system of claim 34, wherein said physical perturbation is continuous along the axial length of the tube. 37. A method for containment of a fluid, comprising: providing a tube comprising an inner layer defining a first fluid pathway and an outer layer thereby forming a second fluid pathway between said inner and outer layer, said second fluid pathway comprising a plurality of channels extending substantially along an axial length of the tube;reversibly sealing said first fluid pathway directly from the atmosphere or separate containment device at an axial end of said tube with a first fitting comprising a first venting mechanism for venting at least part of a first fluid in the first fluid pathway; andreversibly sealing said second fluid pathway directly from the atmosphere or separate containment device at an axial end of said tube with a second fitting comprising a second venting mechanism for venting at least part of a second fluid in the second fluid pathway. 38. The method of claim 37, further comprising measuring the pressure of the first fluid pathway and measuring the pressure of the second fluid pathway. 39. The method of claim 38, further comprising limiting a first pressure of the first fluid so that said first pressure is less than a pressure of the second fluid. 40. A containment kit comprising: a pipe comprising a thermoplastic inner layer, a reinforcing layer, and an outer layer, that includes at least two distinct passages for fluid, at least one of the passages comprising a plurality of channels extending substantially along an axial length of the tube; anda first fitting comprising a first venting mechanism for venting at least part of a first fluid in one of the passages and a second fitting comprising a second venting mechanism for venting at least part of a second fluid in the other passage, the first and the second fittings adapted to reversibly seal the two distinct passages for fluid directly from the atmosphere or separate containment device. 41. The containment kit of claim 40, further comprising a means for pressure measurement.
