For a cast-iron natural gas main, initial replacement options for Peoples Gas in Chicago seemed straightforward—plastic or steel pipes. Logistical, operational and system constraints led the utility to explore an alternative solution: trenchless pipe-lining technology.

BEM Pipeline Assessment For Railroad Crossing
Assessing ferrous pipe walls provides critical data to determine the condition and integrity of pipelines. When a utility needed to assess a section of a 20 inch cast iron main that runs under a railroad right-of-way, Broadband Electromagnetic Probe (BEM) accurately assessed the condition and the degree of corrosion or graphitization.

CIPL: A Proven Technique for Main Renewal
Bridges to No Repair
In 30 years, I haven’t met a utility that didn’t have pipelines along bridges in their inventory. As bridges age, so do the pipelines. We are all getting older. Over forty percent of the bridges in the US are over fifty years old. In the Northeast, gas pipelines and bridges are typically 75 - 100 years old.
World Record 42-Inch Gas Main CIPL
Records are made to be broken, and the world record CIPL in summer 2019 of a 42-Inch Cast Iron Gas Main in a complex layout buried under eight lanes of the Garden State Parkway in East Orange NJ was a breakthrough technological achievement building upon past experience, and fresh technical innovations. It was possible because of lessons learned in overcoming challenges on previous CIPL projects renewing progressively larger diameter CI gas mains.
