Mannesmann Aktiengesellschaft, Düsseldorf _f Mannesmannufer 1b * Sealing ring for pipe connections «

The "Merung" relates to a sealing ring for pipe connections which is particularly suitable for pipes with flanged flanges, which are loosely arranged behind the flares and with a ** other screwed planschrings are connected "

So far, splashes have been used, for example, on circulation pipes for heating oil « Storage tanks mainly welded to pipes or pipe sections »The disadvantage of a pipe connection with welded-on puddles is above all that it is a very rigid "connection that is not suitable for any Compensate for inaccuracies due to minor radial, axial or angular displacements »It is known that one wanted to counteract this disadvantage by attaching the inner planar edge, which corresponds to the clear pipe diameter, to the The bottom side beveled at 45 and placed a gasket with a triangular cross-section between the pool. "This solution brought no substantial gain, ».

The innovation avoids the disadvantages of the previously known sealing rings for pipes with flared flanges * The sealing ring according to the innovation has several spaced apart and parallel to its inner circumference Central axis arranged lug-shaped Yor projections on «

As a result, it is achieved that within the clear pipe <* or * The crimped area and thus fixed to the restricted crimped area required for sealing «

The tab-shaped projections are on both sides of the central plane of the sealing ring arranged opposite one another or offset "To prevent the liquid * flowing through the pipe connection not hindering more than necessary are the priorities «... Cracks rounded or flattened towards their ends.

Another embodiment of the sealing ring according to FIG The new feature is the tab-like projections that have already been laid out only on one side of the central plane on "It is more economical to manufacture because of the lower material expenditure *

In the drawing, the innovation is shown in two sections and a top view «,

Fig »1 shows a pipe connection with a sealing ring 7» which has tab-like projections on both sides of the central plane. The flat rings 5 and 6 rest on the flanged flanges 3 and 4 of the tubes 1 and 2. Between the pipe ends or Sealing surfaces formed by the flanges, the sealing ring 7 lies with the actual sealing web 8 and the tab-like projections 9 »

In Fig * 2 another embodiment of the sealing ring is shown, which is only on one side of the central plane. has jumps 9 *

Fig * 3 shows a plan view that is common to both embodiments

of the sealing ring applies.
