The pressure vessel includes an outer tube, end caps at opposite ends of the tube, and an inner tube located within the fiber bundle. The inner tube is fixedly mechanically connect
An air separation module comprising a bundle of hollow elongated membranes, and a pressure vessel enclosing the bundle. The pressure vessel includes an outer tube, end caps at opposite ends of the tube, and an inner tube located within the fiber bundle. The inner tube is fixedly mechanically connected at opposite ends to the end caps to form a structural spine of the pressure vessel, whereby loads acting on the air separation module are transferred between the end caps primarily by the center tube.

What is claimed is: 1. An air separation module comprising a bundle of hollow elongated membranes, and a pressure vessel enclosing the bundle, the pressure vessel including an outer tube, end caps at opposite ends of the outer tube, and an inner tube located within the fiber bundle, the inner tube
What is claimed is: 1. An air separation module comprising a bundle of hollow elongated membranes, and a pressure vessel enclosing the bundle, the pressure vessel including an outer tube, end caps at opposite ends of the outer tube, and an inner tube located within the fiber bundle, the inner tube being fixedly mechanically connected at opposite ends to the end caps to form a structural spine of the pressure vessel, such that axial loads acting on the air separation module are transferred between the end caps primarily by the inner tube. 2. An air separation module according to claim 1, wherein at least one end of the outer tube is connected to the respective end cap by a connection that permits limited axial movement of the outer tube relative to the end cap. 3. An air separation module according to claim 2, wherein the connection includes telescoping portions of the outer tube and respective end cap. 4. An air separation module according to claim 3, including an annular seal interposed between the telescoping portions. 5. An air separation module comprising a bundle of hollow elongated membranes, and a pressure vessel enclosing the bundle, the pressure vessel including an outer tube, end caps at opposite ends of the outer tube, and an inner tube located within the fiber bundle, the inner tube being fixedly mechanically connected at opposite ends to the end caps to form a structural spine of the pressure vessel, whereby loads acting on the air separation module are transferred between the end caps primarily by the inner tube; wherein the connection includes telescoping portions of the outer tube and respective end cap; wherein the telescoping portions include anti-rotation devices preventing rotation of the outer tube relative to the respective end cap. 6. An air separation module according to claim 5, wherein the anti-rotation devices include cooperating axially extending grooves and ribs received in the ribs. 7. An air separation module according to claim 6, wherein the grooves and ribs further cooperate to limit the amount of overlap between the telescoping portions. 8. An air separation module according to claim 1, wherein one of the end caps has a central threaded portion screwed onto a correspondingly threaded end portion of the inner tube. 9. An air separation module comprising a bundle of hollow elongated membranes, and a pressure vessel enclosing the bundle, the pressure vessel including an outer tube, end caps at opposite ends of the outer tube, and an inner tube located within the fiber bundle, the inner tube being fixedly mechanically connected at opposite ends to the end caps to form a structural spine of the pressure vessel, whereby loads acting on the air separation module are transferred between the end caps primarily by the inner tube; wherein one of the end caps has a central threaded portion screwed onto a correspondingly threaded end portion of the inner tube; wherein the other end cap has a central portion telescopically mated with an end of the inner tube, and an attachment member has an inner portion threaded into the end of the inner tube, a central portion engaging an outer side of the end cap for securing the end cap to the inner tube, and an outer dagger portion extending from the end cap to provide for telescopic coupling to an external component. 10. An air separation module according to claim 9, wherein the central portion and/or dagger portion is/are provided with wrenching surfaces for a wrench used to rotate the attachment member for securement to the inner tube or removal from the inner tube. 11. An air separation module according to claim 1, wherein the fiber bundle and end caps can move axially relative to the outer tube to accommodate differential thermal expansion or contraction. 12. A method of assembling an air separation module, comprising the steps of securing a first end cap to an end of a central tube, installing a bundle of fibers around the central tube, assembling an outer tube to the first end cap, with the outer tube surrounding the bundle of fibers, assembling a second end cap to the outer tube, and after the foregoing steps, screwing an attachment member into an end of the central tube to axially hold the second end cap to the central tube.
