Abstract
A hose designed to facilitate supply and return of cryogenic fluid such as a liquefied gas includes supply and return conduits wrapped in multiple layers of reflective metallized material, which is surrounded by a layer of foam material which is, in turn, surrounded by a protective outer layer such as, for example, a woven cover. The conduits are made of a material such as polytetrafluoroethylene. The inventive hose is lightweight and maintains flexibility for extended periods of time with cryogenic fluid flowing through the conduits.
