A conduit (100) for transporting a fluid comprises a first collar (102), a second collar (103), a bellows (108), and a sensor (116). The bellows (108) comprises a central axis (180), a first corrugated outboard ply (114), a corrugated inboard ply (110), interposed between the first corrugated outboard ply (114) and the central axis (180), 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 corrugated inboard ply (110), the first corrugated outboard ply (114), and a weld-through ring (150) are welded to the first collar (102) and the second collar (102). The second corrugated outboard ply (112) is not hermetically coupled to the first collar (102) or the second collar (103). The sensor (116) is communicatively coupled with the interstitial space (126).
