This disclosure relates to a hose, such as a fire zone hose, that can include an inner tube, a thermal protection sleeve and a braided member. The inner tube can form a flow path for conveying fluid. The thermal protection sleeve can be disposed around the inner tube. The thermal protection sleeve can include an inner surface and an outer surface such that the inner tube is positioned inwards from an inner surface of the thermal protection sleeve. The braided member can be disposed around the thermal protection sleeve, such that the braided member deforms the outer surface of the thermal protection sleeve. Additionally, the hose can include a braid retainer. The braid retainer can be disposed around an end of the braided member to secure the braided member to the thermal protection sleeve.

A conduit for transporting a fluid comprises a first collar, a second collar, and a bellows. The bellows comprises a corrugated inboard ply, a corrugated outboard ply, and an interstitial space, interposed between the corrugated inboard ply and the corrugated outboard ply. The conduit additionally comprises a first weld, hermetically coupling the corrugated inboard ply and a first outer collar portion, a second weld, hermetically coupling the corrugated outboard ply and a first inner collar portion, a third weld, hermetically coupling the corrugated inboard ply and a second outer collar portion, a fourth weld, hermetically coupling the corrugated outboard ply and a second inner collar portion, and a first sensor, communicatively coupled with the interstitial space.

An end fitting including an end part of the tubular sheath, an end section of each elongate element, an end vault, and a cover defining a chamber for receiving each end section. The end fitting includes at least one transducer for generating an ultrasonic wave guided in the elongate element, the generation transducer being placed on the elongate element in the receiving chamber, the generation transducer having a volume of less than 200 mm.sup.3, in particular comprised between 20 mm.sup.3 and 50 mm.sup.3.

A hose which automatically expands longitudinally and automatically expands laterally upon the application of a pressurized liquid is disclosed. The hose can automatically expand longitudinally up to six times its unexpanded or contracted length. Upon release of the pressurized liquid within the hose, the hose will automatically contract to a contracted condition. The hose includes an inner tube made from an elastic material and an outer tube made from a non-elastic material. The inner tube is positioned concentrically within the outer tube in both a contracted condition and an expanded condition. The outer tube is secured to the inner tube only at a first end of the inner and outer tubes and at a second end of the inner and outer tubes. The outer tube moves laterally and longitudinally with respect to the inner tube when the tubes are transitioning between a contracted condition and an expanded condition.
