Abstract

A lining tube for reconditioning a defective sewer pipe has an inner film tube, around which is disposed a radially expandable layer of fiber material that is impregnated with a curable reactive resin. The inner film tube has a connecting section that extends in longitudinal direction thereof and connects two circumferential portions of the inner film tube that run parallel to one another to give an inner film tube which is continuous over its circumference and has a defined nominal diameter. The connecting section has an intended fracture site that extends along the inner film tube and can be parted by introducing a pressure medium into the inner film tube in circumferential direction, in order to expand the inner film tube and the layer of fiber material disposed thereon radially beyond the nominal diameter. There is also described a method of producing and of installing such a lining tube.
