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.
