Abstract: An interconnection arrangement (100) is disclosed for structurally interconnecting together pipe segments (102, 104) with a coupling device (106). In one embodiment, the coupling device is a sleeve coupling (106) having an inner diameter larger than the outer diameters of the pipe segments (102, 104). A set of four clips (118) are employed, with each clip (118) having a lip (120) and a series of tines (126). The clips (118) are engaged with longitudinal edge surfaces of the sleeve coupling (106), and the pipe segments (102, 104) are telescoped into the coupling (106). The tines (126) of the clips (118) "bite" into the inner surface (114) of the sleeve coupling (106), and the outer surfaces (108) of the pipe segments (102, 104).

Abstract: A metal chimney assembly with floating casing walls supported by expansion clips that allow differential expansion longitudinally and radially of banded together chimney wall sections. The clips are attached to interior flue walls and extend outwardly for engagements into retainers on inner circumferences of exterior casing walls and adjacent thereagainst for holding the casing walls in a spaced relationship with the flue walls during expansion and contraction of the chimney wall sections.
