<p>The invention relates to a lining tube for refurbishing fluid-conveying pipe systems having a) at least one reinforced inner film tube on the basis of a thermoplastic plastic, b) at least one external film tube on the basis of a thermoplastic plastic, and c) at least one resin-impregnated fibre tube between at least one inner and at least one outer film tube. At least one inner film tube, which is in contact with at least one fibre tube, has a film strip on the inner surface facing away from the fibre tube, which film strip is oriented in the longitudinal direction of the film tube and of which the modulus of elasticity in the circumferential direction of the inner fibre tube is higher than the modulus of elasticity of the film from which the inner fibre tube is formed in the same direction under identical conditions.</p> |
