The method includes the steps of providing access to the inner conduit space of the tubular conduit and snugly fitting the sealing member onto the protruding portion of the at least one service connection in surrounding relation therewith. The liner and the sealing member together form a unitary structure and a seal about the protruding portion of the at least one service connection once the first curable resin and the second curable resin have hardened.
A method and system of detecting a service entrance in a conduit having a rehabilitation liner, comprising generating heat using a heat source; introducing the heat into the lined conduit; allowing the lined conduit to cool; generating a thermal image of the lined conduit using an infrared camera system; detecting temperature differentiations in the lined conduit in order to detect a service entrance wherein the service entrance is a non-protrudingservice entrance, a partially-protruding service entrance or a service entrance in a saddle fixed to the conduit.
A plug for a tubular service entrance of a conduit, wherein the plug includes a core body having a central hollow channel extending from a first end to second end of the core body; at least one flexible fin extending radially outwardly from the core body and having an outer diameter greater than the inner diameter of the tubular service entrance so that the plug is adapted to fit tightly into the tubular service entrance, and wherein the at least one flexible fin is deformable to adapt to the shape of the service entrance and apply a lateral force against the inner diameter of the service entrance. A plug dispensing magazine for storing and dispensing service entrance plugs to be service entrances of a conduit prior to installation of a liner in the conduit and a method of sealing the service entrances.
