Abstract

By applying material on only one side in the case of a revision, seal rings can be easily rebuilt and reused.

Claims (13)

1. A repaired ring for sealing comprising:

opposite contact surfaces, wherein the repaired ring was previously in use as a new ring and a worn material resulting from operation of the repaired ring was removed by means of processing the opposite contact surfaces, and in which a thickening is present on only one of the opposite contact surfaces after the worn material is removed to compensate for a removal of the worn material from both the opposing contact surfaces.

2. The repaired ring as claimed in claim 1 , in which a welded-on layer is present as thickening, wherein the repaired ring has another material and/or another microstructure in the thickening.

3. The repaired ring as claimed in claim 1 , in which the thickening is performed by means of an insert ring in a depression.

4. The repaired ring as claimed in claim 1 , in which the repaired ring is metallic.

5. The repaired ring as claimed in claim 1 , in which the new ring constitutes a forged part.

6. A method for repairing a ring, comprising:

removing a worn material from a first contact surface and a second, opposing contact surface, the worn material resulting from operation of the ring; and

applying a material to only one of the first contact surface and the second, opposing contact surface to compensate for the removing of the worn material from both the first contact surface and the second, opposing contact surface.

7. The method as claimed in claim 6 , in which a welded-on layer is present as thickening, wherein the repaired ring has another material and/or another microstructure in the thickening.

8. The method as claimed in claim 6 , in which the thickening is performed by means of an insert ring in a depression.

9. The method as claimed in claim 6 , in which the repaired ring is metallic.

10. The method as claimed in claim 6 , in which an original ring constitutes a forged part.
