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°.

Abstract: A screwed pipe connection for connecting a pipeline including a connection end having a formed wall region. The screwed pipe connection includes a connection part and a union joint part. Proceeding from the end face of the connection end of the pipeline, an outside cross-section of the pipeline increases and is larger than the nominal outside cross-section, then decreases again. Proceeding from the end face, a clear inside cross-section of the connection end is larger than the nominal inside cross-section and decreases to the nominal inside cross-section. The wall thickness on the end face is smaller than the nominal wall thickness, and wherein an inner material difference, resulting from the deviation of the inside cross-section from the nominal inside cross-section, and an outer material difference, resulting from the deviation of the outside cross-section from the nominal outside cross-section, deviate from one another by a maximum of 30 percent.

Abstract: The present invention relates to a device for the deformation of workpieces, in particular for the plastic shaping of pipe ends, with a shaping unit actuated by the pressure of a fluid and with a prestressing unit arranged on a common longitudinal axis and actuated by the pressure of a fluid and also with clamping elements of conical design which can be clamped by means of the prestressing unit, in each case at least one separate pressure space being designed in the shaping unit and in the prestressing unit, which space can be pressurized independently of the pressure space of the other unit in each case. In this connection, the shaping unit and the prestressing unit are interconnected but completely closed off in relation to one another.

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 (?) considerably greater than 45° to the screw-connection axis.
