Abstract:
A sealing arrangement for a flat flanged joint comprising a base body (1) having bearing surfaces (7, 7â€²) on each of its two sides for ring-shaped supports (11, 12) made of a soft material, the bearing surfaces (7, 7â€²) being flat over a large area and being situated essentially directly opposite to each other, at least two ring teeth (2, 3) being provided in the inner radial area of each bearing surface, said soft material supports each being fixed on the bearing surfaces (7, 7â€²), the ring teeth (2, 3), when the arrangement is assembled, coming to rest on the flange surfaces (14, 15), and the soft material supports (11, 12) being at least inwardly limited by the ring teeth (2, 3), characterized in that the wall of the base body (1) has a low thickness of only 0.2 to 2.0 mm, and the ring teeth are shaped by stamping in such a way that the whole wall has an angular or wave-shaped configuration, and a punctual metallic contact with the flange surfaces (14, 15) is enabled, and that said soft material supports (10, 12) on the base body (1) are calculated to be at almost maximum compaction in the mounted state, wherein the stamped inner teeth (2, 3) have spring properties which are selected such that, after demounting the seal from the flange, the depth of teeth can restore to the state as before the mounting and thus the original depth of teeth is recovered.
