  • Patent number: 10724808
    Abstract: A plug assembly is used to block flow through a heat exchanger tube. The plug assembly includes a frusto-conical plug body, a frangible attachment on an end of the plug body, and a ring assembly circumscribing the plug body. When positioned around a larger diameter portion of the plug body, the ring assembly is urged radially outward to seal against and block flow through the tube. An installation device draws the plug body within the ring assembly to set the plug assembly in the tube. The installation device is manually operated, and positions the ring assembly over the larger diameter portion of the plug body by exerting an axial force onto the frangible attachment while simultaneously holding the ring assembly in place. The ring assembly is held in place with a second axial force directed opposite to that of the one applied to the frangible attachment.
