(FR) TUYAU CHAUFFÉ DE MANIÈRE ÉLECTRIQUE
Abstract: front page image
(EN) A heated fluid line comprises an inner tube, an outer sheath, and a heating element. The heating element is disposed between the inner tube and the outer sheath. The heating element comprises an interior core formed of a first metallic material, and an exterior jacket formed of a second metallic material. In one embodiment, the heating element is wrapped around the inner tube and has a round cross-section. In another embodiment, the exterior jacket is non-reactive and resistant to water corrosion, and the outer sheath is moisture impermeable.
