摘要

The exhaust line-flat seal has a metallic sealing plate (10) with exhaust-through openings (12,14) and multiple screw holes (16,18,20,22,24,26) attached to the exhaust-through openings for the passing through of erection screws. The steel sheet layers have supporting beads (42,44,46,48) which are designed as full bead with a bead neck and two bead feet and extend in sections along the sealing bead on the sealing plate. The supporting bead of one steel sheet layer engages in the concave curvature formed by the supporting bead of the other steel sheet layer.
