The method for attaching a connector to a metal pipe (5) with spiral corrugations comprises screwing an externally threaded support ring (2) which into the pipe. An internally threaded compression ring (1) is then screwed on to its outside and a graphite sealing ring (3) is mounted between flat sections (1c, 2b) on the outer ends of the two rings. A section of pipe (7) is mounted outside the sealing ring. Flanges on the connector (4) are then bolted to flanges on the compression ring. |
