ABSTRACT:
Three methods for forming three different, double acting, self-contained swages for joining two small diameter tubes are disclosed. Likewise three double acting small diameter (31/2 inch) combination hydraulic-mechanical swages assembled by the methods are disclosed using hinge arms with indentation tips thereon for deforming and connecting together two small (less than 7 inches or 18 centimeters diameter) telescopic tubes for casing repair or a flow line connection, for example. Two modifications formed by the methods have links connected to the swaging arms so that with increased pivotal movement of the arm and link, a gain results in the mechanical advantage and indentation force.
