ABSTRACT:
A pipe connection has a aped pipe, a screw fitting body having an internal cone, a union nut, screwable onto the screw fitting body, having an internal clamping face, which, in the operating state of the pipe connection, works together with an outwardly projecting retention face of a retention bulge of the pipe which is produced facing away from the pipe end by reshaping and projects radially outward beyond the outer mantle surface of the pipe, and having an adapter ring which is supported on the side facing toward the screw fitting body by a conical clamping face in the internal cone of the screw fitting body. To provide an alternative pipe connection of this type, the adapter ring may be supported in the operating state on the side facing toward the pipe by a radially running contact face on the radially running front face of the pipe end.
