Abstract

A pipe coupling can be coupled with one of its ends to a pipe, and has a clamping band and a tightening device for tightening the clamping band. A cover is provided on the other end of the pipe coupling, and the cover is inserted in the clamping band and can be secured by tightening the tightening device of the clamping band. The invention further relates to the use of the pipe coupling.

First claim

The invention claimed is:

1. A pipe coupling having a first end to be coupled with a pipe, said pipe coupling comprising:
a clamping band;
a tightening device for tightening said clamping band; and
a pot-shaped cover on a second end of said pipe coupling, said cover being inserted into said clamping band and secured by said tightening device, said cover having a convex bottom section projecting inwardly towards an interior of said pipe coupling; and
a sealing element made of an elastic material and arranged in said clamping band, said sealing element configured to line an entirety of an inner surface of said clamping band.

2. The pipe coupling according to claim 1 , wherein an end segment of said sealing element is clamped between said clamping band and said cover.

3. The pipe coupling according to claim 1 , wherein an edge portion of said cover has a conical shape becoming wider towards a free end of said cover, and a surface of said conically-shaped edge portion facing said clamping band has a positive fit on a correspondingly-shaped segment of said sealing element.

4. The pipe coupling according to claim 3 , wherein said cover has a cylindrical segment having a positive fit on a correspondingly-shaped segment of said sealing element.

5. The pipe coupling according to claim 4 , wherein said cylindrical segment of said cover connects to said conically-shaped segment of said cover inside of said pipe coupling.

6. The pipe coupling according to claim 1 , wherein said cover has a cylindrical segment having a positive fit on a correspondingly-shaped segment of said sealing element.

7. The pipe coupling according to claim 1 , wherein said cover is completely surrounded by said clamping band.

8. The pipe coupling according to claim 1 , wherein said clamping band has a pair of end faces and an inward-directed flange on at least one of said end faces, said flange defining a stop for said cover inside said clamping band.

9. The pipe coupling according to claim 1 , wherein said clamping band is formed of a continuous, tubular, curved band, and a gap is defined between ends of said clamping band, said tightening device being configured to vary a width of said gap.

10. The pipe coupling according to claim 1 , further comprising an anchoring ring having a truncated cone shape, said anchoring ring projecting into said interior of said pipe coupling and being arranged at said first end of said pipe coupling opposite said second end with said cover.

11. A method of using said pipe coupling according to claim 10 comprising temporarily closing off a pipeline during testing of one or more pipe functions by applying said pipe coupling to the pipeline.

12. The method according to claim 11 , wherein said testing of one or more pipe functions comprises at least one of testing resistance to pressure and leak testing.

13. A method of using said pipe coupling according to claim 1 comprising installing said pipe coupling on a pipeline to close off the pipeline.

14. A method of using said pipe coupling according to claim 1 comprising applying said pipe coupling to a last module of a modular arrangement of a gas engine for closing the last module.
