Abstract
A sealing arrangement between a pipe flange and a screw-on surface for the pipe flange, in which an abutment surface is provided at either the screw-on surface or the pipe flange which extends perpendicularly to the abutment surface of the flat seal in the direction toward the oppositely disposed abutment surface of the pipe flange or screw-on surface, and which is at least approximately tangent to the outer contour of the flat seal at a circumferential place outside of the point of intersection of a line of symmetry with the outer contour of the flat seal; rejection lugs are provided at the outer contour of the flat seal at those places which are disposed opposite the contact places between the abutment surface and the outer contour of the flat seal in relation to the line or lines of symmetry.
