管道连接件
摘要：
本发明涉及一种用于连接尤其是金属的薄壁的导管(1)的管道连接件，包括：带有经变形的连接部段的导管(1)，该连接部段从其连接端开始以一锥角截锥状地增大并且在该处在其外周面上形成了环绕的密封面(7)并且具有与该密封面邻接的带有止挡面(9)的肩部。此外管道连接件包括连接管套(20a)，其带有连接螺纹(25a)和连接孔(23a)，该连接孔从其开口开始以与在密封面(7)的区域中的连接部段的锥角相适配的锥角以截锥状减小，并且在该处在内周上形成了用于贴靠在密封面(7)上的环绕的连接面(27a)；以及锁紧螺旋连接件(10a)，其带有张紧螺纹(13a)且带有贯通开口，该贯通开口在内周上具有用于贴靠在止挡面(9)上的环绕的张紧面(15a)。在密封面(7)的区域中的连接部段的锥角以及在连接面(27a)的区域中的连接孔(23a)的锥角为38°到50°。本发明还涉及用于根据本发明的管道连接件的导管(1)和连接管套(20a)。
摘要（英）：

The invention relates to a pipe connection for connecting an in particular metal thin-walled pipeline (1), comprising a pipeline (1) having a shaped connecting segment, which connecting segment grows larger from the connecting end of the connecting segment in the form of a frustum of a cone at a cone angle and forms a circumferential sealing surface (7) there on the outer circumferential surface of the connecting segment and has a shoulder having a stop surface (9) adjacent to the sealing surface. Furthermore, the pipe connection comprises a connection stub (20a), which has a connection thread (25a) and a connection bore (23a), which decreases in size from the opening of the connection bore in the form of a frustum of a cone at a cone angle that is matched to the cone angle of the connecting segment in the region of the sealing surface (7) and which forms, there on the inner circumference, a circumferential connection surface (27a) for contacting the sealing surface (7), and a union threaded part (10a), which has a clamping thread (13a) and a passage opening, which has, on the inner circumference, a circumferential clamping surface (15a) for contacting the stop surface (9). The cone angle of the connecting segment in the region of the sealing surface (7) and the cone angle of the connection bore (23a) in the region of the connection surface (27a) are 38 degrees to 50 degrees. The invention further relates to a pipeline (1) and a connection stub (20a) for a pipe connection according to the invention.
