ABSTRACT:
A connection between the end of a cylindrical pipe inserted into a hole in a plate for connection there with, the connection being fluid-tight and capable of resisting a torsional couple; the connection is effected by first expanding the pipe-end with respect to the original pipe profile and by shaping the cross-section of the outer circumference of the expanded pipe-end and the inner wall of the hole in the plate such that the projection of the zone of contact upon a plane perpendicular to the axis of the pipe differs from a pure circular form.
