COUPLING DEVICE FOR TUBULAR MEMBERS AND INSTALLATION TOOL |
摘要 |
A coupling device includes a coupling body and a collar adapted to engage a tubular member in a permanent swaged connection. The coupling device includes axially spaced front and back ferrules which engage during swaging to provide a plurality of seals intermediate the ferrules and the tubular member as well as the coupling body. The back ferrule includes a central region having a generally cylindrical wall that is elastically/plastically deformed to a corrugated tube-like shape during swaging to enhance the maintenance of the seals. A portable installation tool for swaging the coupling body and collar to the tubular member is hydraulically actuated. |
