T-pipe for connecting reduced branch pipe to main pipe and method for producing such T-pipe

本发明涉及一种用于将一根异径支管连接到一根主管上的T形管，并且涉及一种用于制造这种管的方法。本发明的特征在于，所述T形管包括热塑性连接件(1)，连接件(1)包括用于所述支管的连接部(2)以及基部(3)，基部(3)基本上与所述主管的曲率相匹配，并且沿着连接部(2)的中心轴线方向上看，基本上呈矩形，所述基部被对焊在一个尺寸近似于所述主管并且宽度近似于基部(3)的管环(4)上，来取代一个从所述管环上去除并且尺寸近似于基部(3)的部分。 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).
