<p>A seal plug (10) and installation tool (60) for providing fluid access to a fluid distribution pipeline (12) having an internal liner (13) affixed therein and a bore hole (150) formed therethrough. The seal plug includes a body (11) having an enlarged diameter head (16) and an elongated stem (14), the stem and head having a fluid transmission passage (20) therethrough. An expandable anchoring member (18) is axially movable on the stem having an unexpanded diameter less than the diameter of the bore hole so that the anchoring member may be passed therethrough and thereafter expanded to a diameter larger than [that] the pipeline bore hole. The installation tool is removeably attached to the pipeline and is releasably engageable to the seal plug, and is used to insert the seal plug within the pipeline. The tool then draws the expanded anchoring member towards the head to securely connect the seal plug to the pipeline and liner. A sealant (146) is positioned at the junction of the pipeline, liner, and seal plug.</p> |
