Abstract:
1. A method of blocking media flow through a pipe having a longitudinal axis and an annular wall defining an outer wall surface and an inner wall surface, wherein the inner wall surface defines an inner pipe diameter, the method comprising the steps of: attaching a fitting to the outer wall surface of the pipe, wherein the fitting includes a channel providing access to a portion of the outer surface of the pipe; forming two substantially aligned apertures in the wall of the pipe and two scalloped sections substantially aligned with the apertures on the inner wall surface of the pipe using the access provided by the fitting, wherein the apertures have a diameter larger than the pipe inside diameter; inserting a plug assembly into the pipe through one of the apertures, wherein the plug assembly includes a resilient plug, the resilient plug having an outside diameter smaller than the aperture diameters and larger than the inner pipe diameter, and wherein a portion of the plug assembly extends through the other aperture; and expanding the resilient plug to engage the scalloped sections.
