Abstract
A conduit assembly includes a dielectric tube having a first end and a second end, a first metal tube including a first flange coupled to the first end of the inner dielectric tube, the first flange including relief openings, a first dielectric ring coupled to the first flange, a second metal tube including a second flange coupled to the second end of the inner dielectric tube, the second flange including relief openings, and a second dielectric ring coupled to the second flange.
Claims20
A conduit assembly, comprising:
- a dielectric tube having a first end and a second end;
- a first metal tube comprising a first flange coupled to the first end of the dielectric tube, the first flange comprising relief openings;
- a first dielectric ring coupled to the first flange;
- a second metal tube comprising a second flange coupled to the second end of the dielectric tube, the second flange comprising relief openings;
- a second dielectric ring coupled to the second flange;
- wherein:
- the relief openings in the first flange and the second flange comprise discontinuous slot segments that extend circumferentially through each flange;
- the first flange and the second flange further comprise tab segments;
- and
- each tab segment has a first portion adjacent to a respective one of the discontinuous slot segments and an opposing second portion substantially coextensive with circumferential edge of the flange.
