Abstract (en)
[origin: WO9612134A1] The invention concerns a method and device for renovating drains which enable connections to domestic connection pipes to be improved. According to the invention pipes made of thermoplastic plastics are introduced into a drain (1). The plastics pipes are then heated in the area covering the connection and this area is subsequently deformed into the domestic connection pipe (3), in the manner of a connection piece, by a telescopic deformation member. During this movement, the deformation member (7) entrains an annular transitional formed part (10) and, as the deformation member moves back, it deposits said part (10) on the interior of the connection piece formed in this way. It is also possible to insert a connection formed part (14) which is sealed with respect to the transitional formed part (10) and the domestic connection (3) in order to improve further the connection to the domestic connection pipe.
