Abstract
A device is provided for use in securing a remnant of a tube through a wall of a pressure vessel. The device include an anti-ejection device for attachment to the remnant on an interior side of the pressure vessel and an end cap for attachment to the remnant on an exterior side of the pressure vessel for sealing an open end of the remnant. The anti-ejection device includes an anti-rotation member for constraining the remnant and the anti-ejection device against relative rotation therebetween. A bolt connects the anti-ejection device, the remnant, and the end cap.
Claims18
A device for use in securing a remnant of a tube through a wall of a pressure vessel comprising:
- an anti-ejection device for attachment to the remnant on an interior side of the pressure vessel, wherein the anti-ejection device defines a lumen passing axially therethrough, wherein the remnant defines a lumen passing axially therethrough, and wherein the lumen of the anti-ejection device is configured for axial alignment with the lumen in the remnant;
- an end cap for attachment to the remnant on an exterior side of the pressure vessel for sealing an open end of the remnant;
- and
- a connector for passage through the lumen of the anti-ejection device and the lumen of the remnant, wherein the end cap defines an inner threaded channel axially aligned with the lumen of the anti-ejection device and the lumen of the remnant, wherein the connector comprises an elongate member having a threaded end for connection to the end cap.
A device for use in securing a remnant of a tube through a wall of a pressure vessel comprising:
- an anti-ejection device for attachment to the remnant on an interior side of the pressure vessel;
- an end cap for attachment to the remnant on an exterior side of the pressure vessel for sealing an open end of the remnant;
- further comprising a connector for connecting the anti-election device, the remnant, and the end cap;
- wherein:
- the anti-election device defines a lumen passing axially therethrough;
- the remnant defines a lumen passing axially therethrough, the lumen of the anti-ejection device configured for axial alignment with the lumen in the remnant when, in use, the anti-ejection device is attached to the remnant;
- the end cap defines an inner threaded channel axially aligned in use with the lumens of the anti-election device and the remnant;
- and,
- the connector comprises an elongate member for passage through the lumen of the anti-ejection device and the lumen of the remnant, and a threaded end for threaded connection to the channel of the end cap;
- wherein the lumen of the anti-ejection device defines an upper recessed section and a lower lumen section, the upper recessed section being greater in cross-sectional dimension than the cross-sectional dimension of the lower lumen section, the upper recessed section defining a rim surface;
- and
- the device further comprises a locking cup seated on the rim surface of the upper recessed section for securing the connector to the anti-ejection device.
