Abstract: The subject matter of the invention is a lining hose as a composite hose for lining a pressure pipe to be renovated, comprising at least one first layer and a second layer which adjoins the first layer, the first layer forming a substantially fluid-tight and/or gas-tight diffusion barrier and the second layer being a textile fabric soaked in a resin and being provided for an all-over adhesive connection to an inner wall of the pressure pipe to be renovated, the lining hose being flexible in a state in which the resin has not cured. The second layer is at least 3 mm thick, the textile fabric and the resin being selected such that the lining hose forms a self-supporting pipe in a state in which the resin has cured. The invention also relates to a method for renovating a pressure pipe using such a lining hose and a corresponding renovated pressure pipe.

Abstract: A tube liner for lining pipelines includes an inner film tube, an outer film tube, and an interdisposed layer of fiber material which is impregnated with a curable material. At least one of the two film tubes are formed by at least one tube web which includes a carrier film and a fleece layer which is applied to the film side of the carrier film that is facing the layer of fiber material. The web edges of the carrier film that overlap one another in the circumferential direction of the tube are connected to one another. The web edge that in the overlap region is facing away from the layer of fiber material is formed singularly by the carrier film which in the overlap region protrudes beyond the fleece layer and which is adhesively bonded or welded directly to the carrier film of the web edge that in the overlap region is facing the layer of fiber material.
