摘要： The present invention relates to a T pipe for connecting a reduced branch pipe to a main pipe and to a method for producing such a pipe. The invention is characterized in that said T pipe comprises a thermoplastic connection piece (1) including a connection (2) for the branch pipe as well as a base part (3) essentially matching with the curvature of the main pipe and being essentially rectangular viewed in the direction of the central axis of said connection (2), said base part being butt welded to a pipe ring (4) having a size similar to that of the main pipe and a width similar to that of the base part (3), instead of a piece removed from said ring pipe and having a size similar to that of the base part (3).
