Longest Gas Lining Project in the U.S. Completed
A large gas distribution company on the east coast was notified
that a Water Department was planning a large-scale construction
project to replace a 16 inch pipe that was in close proximity to
their 20 inch cast iron gas main. Several repair and replacement
methods were considered, to either replace the pipe or to use cured-in-place
lining to ensure joint integrity after the water pipe construction.
The cured-in-place lining offered by Kerr Engineered Sales had a
number of benefits. Fewer excavations would be needed, so restoration
liabilities and costs would be reduced, disruption to traffic and
businesses would be limited, the risk of damaging other buried utilities
would be all but eliminated, and the cost of renewal would be considerably
less than replacement. This company was one of the early pioneers
in lining and felt confident that Progressive
Pipeline Management and the StarlineĈ
liner product would meet their needs. Secondly, they needed a way
to isolate the gas mains for the rehabilitation work. TDW
Services was called on to provide the necessary Linestopping
services and fittings to assist on the project. The 20 inch cast
iron pipe lining project, about 7000 feet, represents the longest
gas lining job in the U.S. The 20 inch main was located in Brooklyn,
NY along a busy thoroughfare. KeySpan was pleased with the multiple
solutions that Kerr orchestrated and expects to operate this large-diameter
main for many years to come.
“We expect to have more of these types of projects and
based on the success weíve had with Starline®, lining the pipe
and TDWS Services will be considered a viable if not a preferred
maintenance option”says Susan Fleck, KeySpan.
