Pipeline Ultraisolation Group (PLUG)

PLUG, Pipeline Ultraisolation Group, is developing the latest in a series of tools that are designed to seal off flow in an active pipeline where a valve may not be present. PLUG offers an alternative to purging the entire line with nitrogen, or hot tapping into a live pipeline to install a temporary plug. Unlike hot tapping, the use of an inline plugging pig leaves no fittings on the line, thus eliminating a potential site for future corrosion. The plug’s applications include repair work, reroutes, mainline valve changeouts, launcher and receiver valve changeouts, removal of old line stop fittings, and any other applications where and line stopping technologies have been used in the past.
