The method and equipment for sealing and/or renovating a pipe involves the feed of liquid coating material to at least one mouthpiece (7) which is pushed through the pipe (22) to rotate around an axis parallel to the central axis of the pipe to eject material through at least one aperture (20) radial to the mouthpiece axis against the pipe inner wall. The ejected material, after hardening, forms part of the pipe wall. |
