Abstract:
An extended length tube structure includes a first ceramic tube segment having a first end and a second end, and a second ceramic tube segment having a first end and a second end, in which the second end of the first ceramic tube segment is arranged to face the first end of the second ceramic tube segment. A ceramic coupling component is positioned to circumscribe the end-to-end configuration of the tube segments, and is sinter-bonded to the tube segments to form a continuous, extended length tube structure having a seal, such as a sinter bond or an interference bond, that is free of bond materials.

Claim (Index 1):
An extended length tube structure comprising:\n a first ceramic tube segment having a first end and a second end; a second ceramic tube segment having a first end and a second end, the second end of the first ceramic tube segment being arranged to face the first end of the second ceramic tube segment, each of the first and second ceramic tube segments having an inner diameter and an outer diameter; and a ceramic coupling component sinter bonded to the second end of the first tube segment and the first end of the second tube segment such that the first and second tube segments are arranged end to end to form a continuous tube structure, wherein each of the ceramic tube segments forms a seal with the coupling component, wherein the seal has at least one performance characteristic selected from the group consisting of:\n i) a Shear Strength not less than about 25 MPa; \n ii) a Nitrogen Seal Performance of not greater than 10%; \n iii) a Helium Seal Performance of not greater than 10%; \n iv) a Vacuum Seal Performance of not greater than 10%.
