Engineering Innovations Emerge from Lining Challenges

The 30-inch turnkey project in Brooklyn’s Gowanus Canal challenged what we thought was possible. There were several times we wondered, can it be done? There was nothing conventional about this project. The drawings showed a pipe configuration I had never seen.

UV CIPP RENEWS 36-INCH STORM DRAIN AFTER OTHERS FAIL

After a previously installed liner failed, UV CIPP proved an ideal solution to rehabilitate a leaking 36-inch storm drain under a heavily trafficked road at a manufacturing facility in New Jersey. Interestingly, the leaking stormwater drainpipe had been lined a few years prior.

Eversource Evaluates Trenchless Technology

Eversource Engineers analyze PPM’s CIPL for a capstone project to rehabilitate a leaking bridge pipeline. Read about the role of trenchless technologies in Eversource’s portfolio of solutions for improving safety, reliability, repairing leaks and reducing fugitive emissions.

Gas Utilities & PPM: Proactive Approach to Lining Steel Mains

Steel gas mains come in a variety of specifics requiring a slightly different approach for reconditioning. A heightened level of awareness needs to be addressed in these three areas before the lining process begins.

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.

LEAK REPAIR TECHNOLOGY FOR BRIDGE PIPELINES

Starline® Cured-in-place-lining with carbon fiber SRS is an ideal solution to repair gas leaks within bridge pipelines. Of the 614,387 suspension bridges in the U.S, forty two percent are 50 years or older. In the Northeast, gas pipelines and bridges are typically 75 - 100 years old.

Turnkey Alliance Manages Leak-Prone Infrastructure

PPM and Hallen Construction, National Grid’s primary contractor, deliver turnkey and cost effective solutions to line a 24-inch cast iron gas main on a complex project in Queens, New York. The Starline CIPL technology is integral to National Grid’s long-term strategy to manage leaking infrastructure.

LINING A GEOMETRICALLY COMPLEX MESS INVOLVING A LEAKING GAS MAIN

The award winning renewal of a 30 to 36 in diameter leaking high pressure (HP) gas main crosses a river in central New Jersey. It was affectionately named “The Mess” due to multiple complexities that required engineering and design solutions for a successful lining operation.

SUPPORTING OPERATORS AS THEY IMPLEMENT THE 2020 PIPES ACT

The 2020 PIPES ACT incorporates new regulatory requirements that formalize and amplify emission reduction as a component of pipeline safety. Bob Wilson shares tools, technology and practices to consider as operators integrate the mandates into their day-to-day operations.
