ABSTRACT The invention is concerned with a high- pressure resistant multilayer hose structure adapted to conduct and vent gases diffused into the body there- of from gas-containing media conveyed therethrough, the hose having a wall with exterior layers, reinforcing ply layers, gas-conducting layers and an internal backing layer. The internal backing layer is a flexible metal pipe within, and concentric with, the inner surface of the hose wall. A flexible, low gas-permeable layer is concentric with, and is disposed between the internal backing layer and the reinforcing ply layers. A fabric layer is disposed concentrically with and between the outer surface of the flexible metal pipe and the low gas-permeable layer. The reinforcing ply layers are concentric with, and are disposed between the low gas-permeable layer and the exterior layers, the reinforcing plies having gaps through which the gases diffused in the hose wall from the medium con- veyed through the hose are vented from the interior of the hose wall. Embedding layers that are disposed between each layer of reinforcing plies concentric therewith and between the innermost reinforcing ply layer and the low gas-permeable layer are located between the outermost reinforcing ply layer and the outermost layers of the hose, the exterior layers of the hose comprising a cover layer on a fabric carcass which is disposed on the outermost embedding layer.
