Flexible corrugated hose assembly and connecting process

Abstract

For connecting flexible corrugated hoses, which are not provided with fittings, for transporting preferably gaseous media in connection with high-pressure applications, a holderis provided, which receives an exposed end of the corrugated pipeof the flexible corrugated hoseand is pressed together with it to form a metallic seal. The metallic seal is achieved by the surface pressure between the interior wallof an elementof the holder and the ribsof the corrugated pipe. Elastomeric seals, as well as a soldering joint, if desired, can be provided as aids. However, in connection with a preferred embodiment the required sealing is already achieved by the strong pressure against each other of the metallic exterior of the corrugated pipeand the metallic interior of the element. A further elementof the holderfixes a sectionof the sheathingof the flexible corrugated hosein the axial direction, as well as in respect to tilting movements, so that pivot movements of the flexible corrugated hosedo not lead to a relative movement between the corrugated pipeand the holder, in particular the element. Thus, the sealed area remains unaffected, even in case of mechanical tensile or bending stresses of the flexible corrugated hose assembly
