摘要

A method for the connection of a connecting pipe to a by means of a relining pipe made of plastic material repaired main tube, comprising the steps of: locating of the center point a in the vicinity of the to the main pipe facing end of the connecting pipe puncture aperture located in the main pipe of the inner side of the relining pipe, generating an opening in the relining pipe in the region of the localized by heating the center point in said region of the plastic material of the relining pipe of the inner side of the relining pipe, expansion of the opening produced by simultaneous exertion of pressure on the inner side of the relining pipe in the direction of the connecting pipe and heating of the region of the plastic material, on which the pressure is exerted from the inner side of the relining pipe, the application of the plastic material of the projecting in the connecting pipe relining pipe, on the inside of the to the main pipe facing end of the connecting pipe, spot or flat fastening of the plastic material on the inside of the connecting pipe, and flattening of the plastic materials and fastening of the same at the inner side of the connecting pipe.
