Abstract (en)

[origin: WO2013068544A1] Disclosed is a method for lining an existing pipe on the inside, and to an inner lining pipe. The inner lining pipe (7) with a certain original outer dimension is made mainly of polyvinyl chloride. Said original outer dimension is smaller than the inner circumference of the existing pipe (8) to be lined. The inner lining pipe (7) is installed inside the pipe (8) to be lined. After this, the inner lining pipe (7) is expanded in such a manner that its original outer dimension becomes larger by causing a radial orientation in the wall material of the inner lining pipe (7).
