The Joliet Header pipeline was a 16” and 24” O.D. natural gas line that travelled through Crest Hill, Joliet and Rockdale, IL. Along the right of way was a railroad that needed to be bored underneath for a total length of 120 feet. A 26” bore diameter was drilled through solid rock with a 24” casing that got cut off and removed after it was pushed through with a 16” reducer welded onto the end of the casing. Since the casing was cut off, another form of protection on the pipe was needed to prevent scraping, as well as to aid in the grouting process following installation. PipeSak supplied 68 PipeDefender panels to the contractor for extreme protection. When the first panel of PipeDefender was to be installed, a 44” pad of PipeJacket was first wrapped around the pipe, with no overlap. This was done to add friction to the panels and avoid slippage from contact with the rock. The panels were assembled out of trench and then wrapped around the pipe using PipeSak’s QuikZips and strapping to secure the PipeDefender. With the remaining PipeJacket spread along the length of the section, no backward slippage was evident. As the pipe had reached the other side of the bore, PipeDefender had picked up some collapsed clay while remaining intact. PipeDefender was able to successfully protect the pipe from any damages in an efficient and safe manner.
