Cured In Place Lining for natural gas & pressure pipelines: trenchless technology extends life by 100 years

PPM is the sole licensee in North America for the Cured-In-Place-Lining (CIPL) technology for natural gas pressure pipeline rehabilitation. The PPM Starline® CIPL system can line pipelines from 4” to 48” in diameter, creating a durable and impermeable composite pipe within the original pipeline without effecting flow capacity. Ideal for mid-stream and upstream pipeline sector applications for systems operating between 0-350 psi to eliminate inadvertent emission of un-odorized natural gas releases due to leaks and resultant GHG issues. Rigorously and independently tested by PHMSA, academia and industry leaders, the trenchless pipeline rehabilitation technology has been proven to eliminate leaks, methane emissions and extend the life of pipelines by 100 years.

• Seals & eliminates hazardous gas leaks

• Effective for cast iron and steel pipelines

• Project costs often can be captured as a capital expense

• More cost efficient than traditional replacement

• Minimizes excavation and re-construction

• Reduces environmental issues & disruptions that accompany excavation

• Reduces installation time (500ft – 1000ft per day)

• Adds 100 years of new/additional life to pipes

• Improves pipeline flow capacity

• Eliminates leaks & methane emissions

TRUSTED BY NATURAL GAS UTILITIES FOR PIPES ACT COMPLIANCE 

NYSEARCH & CORNELL UNIVERSITY TESTED THE LONGEVITY AND EXTREME CAPABILITIES OF
CURED-IN-PLACE LINED PIPE

NYSEARCH/Northeast Gas Association (NGA) completed a two-year CIPL research and development project in 2015 with support from National Grid, PECO Energy, Public Service Electric and Gas and Con Edison that included funding support from PHMSA. The project was in collaboration with Cornell’s independent pipeline infrastructure experts. The independent testing with lined pipe in live pressurized gas service determined a 100 + year viability of field-aged Cured-in-Place pipe as alternative to full pipeline replacement. CIPL is validated for pipeline renewal and a viable option to conventional replacement methods for cast-iron and steel distribution pipelines.
