|Quick up date on starline trenchless technology…|
• A successful demonstration at National Grid of a new starline product, HPL-G 180, was conducted by Karl Weiss and Progressive Pipeline Management (PPM) in 2007. HPL-G 180 is a rehabilitation for mains up to 180 psi and diameters as small as 6 inches. The development of HPL-G 180 was funded by National Grid and Atmos Energy.
• Two demonstrations of an accelerated, ultraviolet curing system currently under development were conducted with Puplic Service Gas and Electric and Consolidated Edison Company of New York in the fall of 2007. During the first demonstration a 12 inch main was cured at a rate of 3 ft/min and resulted in the lining, curing and final inspection being completed in 5 hours. The curing rate for the second demonstration was increased to 4,5 ft/min and resulted in the cleaning, pre-inspection, lining, curing and final inspection being completed in 9 hours. The accelerated curing system will be commercially available in the summer of 2008.
• PPM recently rehabilitated a leaking fire-water under a concrete
foundation near the main reactor building at the Exelon Nuclear Power,
Dresden Generating Station in Morris, Il. The possibility to re-route
the 6-inch cast iron pipe or to replace it through the foundation was
not possible. PPM developed and tested a one-way lining progess where
the inversion would stop internally at a desired length because only one
acoess point was poosible. The pressure drum remained in place during
process to hold the liner in-place with the rentention belt. PPM`s robotic
unit was then deployed to “cut-out” the liner just in front
of the inversion “tail”. Using a loop system pre-installed
on the tail, this section of liner and tail was then pulled free from
the pipe using a wich. PPM also development a one-way sand blasting process
to allow for sufficient cleaning.
• In the spring of 2007, PPM installed the longest single inversion of the starline 2000 process in a 10-inch steel pipeline for their client, T.W. Phillips Gas & Oil. The length of the inversion was 995 feet. The pipeline cleaning and waste recovery process, as well as the lengthy inversion of the starline medium pressure liner, was all performed without incident. The 1940s vintage steel main had localized corrosion and ran adjacent to a RR track and river. The use of starline trenchless technology in this application was a “homerun” for the customer in terms of costs savings and reliability.
• Edward “Eddie” Johnston is the new president of starline trenchless technology. Eddie is looking to expand the use of starline products across the nation and into other industries.
