CONDUITS FOR TRANSPORTING FLUIDS AND METHODS OF FABRICATING THE SAME

Abstract:

A conduit (100) for transporting a fluid comprises a first collar (102), a second collar (103), and a bellows (108). The bellows (108) comprises a first corrugated outboard ply (114), a corrugated inboard ply (110), an interstitial space (126), interposed between the corrugated inboard ply (110) and the first corrugated outboard ply (114), and a second corrugated outboard ply (112) within the interstitial space (126). The first corrugated outboard ply (114) and the corrugated inboard ply (110) are hermetically coupled to the first collar (102) and the second collar (103). The conduit (100) additionally comprises a first sensor 116, communicatively coupled with an interstitial space (126). The second corrugated outboard ply (112) is not hermetically coupled to the first collar (102) or the second collar (103).
