Abstract
A fluid-impermeable composite hose has a laminated layer composed of an inner winding layer formed by winding a laminated sheet spirally in a single layer, leaving a gap between every two adjoining turns, and an outer winding layer formed by winding a laminated sheet spirally in a single layer over the gap in the inner winding layer, leaving a gap between every two adjoining turns. The gap of the inner wind layer gives the hose flexibility and prevents the folding of the spirally wound sheet which might result in the failure of the hose to maintain its fluid impermeability.
Claims19
A fluid-impermeable composite hose having a wall comprising a fluid-impermeable laminated layer formed of a laminated sheet which contains a metallic foil, or a metallic layer formed by vapor deposition, wherein the laminated layer comprises an inner winding layer formed by winding a tape of the laminated sheet spirally in a single layer and leaving a gap between every two adjoining turns, and an outer winding layer formed by winding another tape of the laminated sheet spirally in a single layer over the gap in the inner winding layer and leaving a gap between every two adjoining turns.
