NYSEARCH/NGA and Con Edison Demonstrate Cured-in-Place Pipe Liner
On October 21, 2014, NYSEARCH/NGA and Con Edison, with assistance from Progressive Pipeline Management (PPM), demonstrated the rehabilitation of over (300) feet of 8” Cast Iron pipe in Mt. Vernon, NY utilizing the Starline™2000 cured-in-place liner operating procedures. This demonstration was completed as part of a project entitled “Technology Transfer, Demonstration and Post-Mortem Testing of Cast Iron and Steel Pipe lined with Cured-in-Place Pipe Liners”. This project is cofunded by PHMSA and is designed to: 1) gain understanding and support from regulators to use CIPP liners as a rehabilitation/replacement technique, 2) provide an engineering assessment to advance the understanding of CIPP liners as applied to cast iron and steel pipe, and 3) validate the effectiveness of CIPP-lined cast iron and steel pipe through examination of past studies and further testing.
The demonstration at Con Edison added to other NYSEARCH project activities this year including extensive laboratory testing being conducted by experts at Cornell University. The Cornell testing is on several intact segments of lined pipe that were in-service for over (10) years and extracted earlier this year in National Grid and PSE&G territories.
demonstration and lab testing.
Attendees at the demonstration included Chris McLaren of PHMSA, several NY PSC staff and gas colleagues from PECO, National Grid and Con Edison. The attendees had the opportunity to examine one foot segments of pre-installed, internally cleaned, and post-installed segments in lined steel from one section of pipe in Mt. Vernon that had already been lined. They also witnessed the live lining of a second section and various parts of the process including: liner adhesive mixing and application, liner inversion, installation, and initial curing. Attendees also had the opportunity to view a post-lining live camera inspection of approximately 190 feet of 6" steel.
The pictures shown illustrate the scene with the live lining process and discussion among participants with Mario Carbone of Progressive Pipeline explaining the process to various regulators.
For over thirty years, NYSEARCH has worked as a consortium of natural gas Local Distribution Companies (LDCs) who have a common interest and need for research and technology development and demonstration. Today, as part of the Northeast Gas Association (NGA), NYSEARCH manages over (30) projects in various stages of development for LDCs, transmission companies, federal agencies and their manufacturing and commercial partners. NYSEARCH is located in Parsippany, NJ and NGA is headquartered in Needham, Massachusetts.
