  • Patent number: 9568139
    Abstract: A lining element for repairing a connection area between a main pipe and a branch pipe, comprising a layer of resin-absorbing material, wherein at least three flexible, expandable lining parts are connected to each other by at least three connections to form the lining element. Each lining part comprises a main pipe section and a branch pipe section, and side edges. The lining element is characterized in that the lining parts are connected to each other by connecting both side edges of the adjacent branch pipe sections and side edges of adjacent main pipe sections in a continuous fashion.

  • 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.

  • Publication number: 20050092382
    Abstract: The invention pertaining to a device and method for pipe rehabilitation, more specifically to a device and method for rehabilitating the junction of a building connection from a main pipeline into the building service line. With positioning means, a curable pipe lining is positioned at the junction of a building service line from a main line and with transport means the positioning means and the pipe lining are transported to the mentioned junction. The problem of the invention is to provide a device and a method for rehabilitating pipe connections, which simplify the reliable transportation and positioning of the pipe lining relative to the junction region of the building service line to be lined. This problem is solved by an alignment body, which is arranged so that it can move on the transport means and which can be moved into the junction of the building service line, and also by a drive for moving the alignment body into the junction of the building service line.
