  • Apparatus and method for securing a tubular liner in a composite pipe
    Patent number: 7025384
    Abstract: A device for mechanically securing a tubular liner in a pipe having a tubular member and connectors on each end. The connector has a bore with an internal seat that may have grooves and be tapered depending upon the application. The liner extends through the tubular member into the bore. The ends of the liner are radially and plastically deformed into engagement with the seats. An inner ring is positioned inside the liner to retain the end of the liner in engagement with the seat. The inner ring may be held by threads or by radially and plastically deforming it. The connectors are mounted to the tubular member independently of the liner, such as by adhesive. The liner may be replaced by removing the inner rings without affecting the connection between the tubular member and the connectors.
