LINING TUBE, RENOVATED PRESSURE PIPE AND METHOD FOR RENOVATING A PRESSURE PIPE

摘要

The subject matter of the invention is a lining tube as a composite tube for lining a pressure pipe to be renovated, comprising at least one first layer (1) and a second layer (2) which adjoins the first layer (1), the first layer (1) forming a substantially fluid-tight and/or gas-tight diffusion barrier and the second layer (2) 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 tube being flexible in a state in which the resin has not cured. The second layer (2) is at least 3 mm thick, the textile fabric and the resin being selected such that the lining tube 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 tube and a corresponding renovated pressure pipe.
