The invention relates to a threaded pipe joint for welding into an exhaust gas pipe (50) of an internal combustion engine and for receiving an exhaust gas sensor (20), comprising a channel bore (12), which in the axial direction has an end (121) facing the exhaust gas and an end (122) facing away from the exhaust gas, characterized in that the channel bore (12) is provided with a through hole (122). According to the invention, a circumferential, radially inwardly directed flange (14) is provided in the channel bore (12) for bearing against the exhaust gas sensor (20), said flange being spaced apart from the end (121) facing the exhaust gas and from the end (122) facing away from the exhaust gas. 用于焊入内燃机的废气管(50)中并且用于接收废气传感器(20)的螺纹管接头，其具有通道钻孔(12)，该通道钻孔在轴向方向上具有面向所述废气的端部(121)和背离所述废气的端部(122)，其特征在于，在所述通道钻孔(12)中设置有环绕的、在径向上向内指向的、用于贴靠所述废气传感器(20)的凸缘(14)，所述凸缘与面向所述废气的端部(121)间隔开并且与背离所述废气的端部(122)间隔开。
