摘要

Lining Hose, Renewed Pressure Pipe, and Method for Renewing a Pressure Pipe The invention relates to a lining hose as a composite pipe for lining a pressure pipe to be renewed comprising at least a first layer (1) and a second layer (2) that is adjacent to the first layer (1), the first layer (1) forming a substantially fluid tight and / or gas tight diffusion barrier and the second barrier (2) being a textile fabric embedded in a resin and being provided for a surface-wide adhesive connection to an inner wall of the pressure tube to be renewed, the casing hose being flexible in a condition in which the resin is not cured. the second layer (2) is at least 3 mm thick, the textile fabric and resin being selected such that the liner hose forms a self-supporting tube in a condition in which the resin is cured. The invention also relates to a method for renewing a pressure pipe using such a sheath hose and a corresponding renewed pressure pipe. 1/1
