FIELD: production of fittings.SUBSTANCE: invention relates to a flexible pipe for transporting a pressurized, free-flowing medium. Conduit consists of two cross-corrugated to their longitudinal direction tubes made of metal, which are arranged with the gap with the inclusion of a ring spaced concentric with each other. In the annular gap between both pipes there is a vacuum isolation. Outside on the inner tube is a solid reinforcement train is applied, which is fixedly connected to the same at both ends of the inner tube. It consists of tension-resistant strands which, helically one above the other in at least two layers having opposite lay direction wound around the inner pipe.EFFECT: at using the invention design of the conduit is simplified.1 cl, 4 dwg |
