Abstract
A pipe connection for connecting metal thin-walled pipeline. The pipeline has a shaped connecting segment that increases from the end of the connecting segment in the form of a frustum forming a circumferential sealing surface and a shoulder defining a stop surface adjacent to the sealing surface. The pipe connection also includes a connection stub having a connection thread and a connection bore, which decreases in size and defines a circumferential connection surface for contacting the sealing surface. A union threaded part includes a clamping thread and a passage opening, which has, on the inner circumference, a circumferential clamping surface for contacting the stop surface. The cone angle of the connecting segment in the region of the sealing surface and the cone angle of the connection bore in the region of the connection surface are in the range of about 38° to 50°.
