ABSTRACT:
A pipe screw-connection for connecting a pipeline having a connection end with a deformed annular bead, including a connection stub and a screw-connection coupling part, which can be screw-connected to the connection stub in order to retain the pipeline in a sealed manner is provided. The connection stub has an accommodating opening with a radial step surface for axially supporting an end surface of the pipeline and with an inner cone which widens outward away from the step surface. The pipeline can be clamped in, by way of the annular bead, with a form fit between the connection stub and a supporting ring, which is seated on the pipeline between the annular bead and the screw-connection part. The supporting ring, with the annular bead, forms an abutment surface which is at an angle (α) considerably greater than 45° to the screw-connection axis.
