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 corrugated inboard ply ( 110 ), a corrugated outboard ply ( 112 ), and an interstitial space ( 126 ), interposed between the corrugated inboard ply ( 110 ) and the corrugated outboard ply ( 112 ). The conduit additionally comprises a first weld ( 138 ), hermetically coupling the corrugated inboard ply ( 110 ) and a first outer collar portion ( 104 ), a second weld ( 134 ), hermetically coupling the corrugated outboard ply ( 112 ) and a first inner collar portion ( 106 ), a third weld ( 186 ), hermetically coupling the corrugated inboard ply ( 110 ) and a second outer collar portion ( 105 ), a fourth weld ( 184 ), hermetically coupling the corrugated outboard ply ( 112 ) and a second inner collar portion ( 107 ), and a first sensor ( 116 ), communicatively coupled with the interstitial space ( 126 ). |
