  • Publication number: 20120312407
    Abstract: The invention relates to a lining element (10) for the repair of a connection area between a main pipe and a branch pipe, comprising a layer of resin-absorbing material. In a first variant, at least three flexible, expandable lining parts (20) are connected to each other by at least three connections (28) to form the lining element. To manufacture such a lining element, the at least three flexible, expandable lining parts are provided and connected to each other by means of at least three connections to form the lining element. Furthermore, the invention relates to another lining element (100), comprising at least one lining part (102) having a layer of resin-absorbing material, which has a tubular preform, and which is deformable by means of heat and/or forming to achieve a tubular final form.

  • Patent number: 8043656
    Abstract: A method and an apparatus impregnate a lining module for repairing a pipe. An end area of the lining module provided with a resin-absorbing layer and an air-tight, outer coating, is introduced into an air-tight sleeve, and an auxiliary introduction device is fixed at an introduction area of the lining module. The transitions between the lining module and the sleeve and between the introduction area and the auxiliary introduction device are closed off in an air-tight manner by at least one sealing device. The auxiliary introduction device is closed off with respect to the ambient by a releasable blocking device in an air-tight manner in such a way that the chamber, formed by the sleeve and the auxiliary introduction device and optionally also the lining module, is closed in an air-tight manner and an introduction chamber accessible from the outside is provided for filling with resin.
