Starline®2000 Cured-In-Place Lining

The Starline®2000 technology is a Cured-In-Place (CIP) lining process for the trenchless rehabilitation of aging and leaking natural gas pipelines. Existing cast iron and steel gas mains from 3" to 24" in diameter with MAOPs up to 99psi can be completely rehabilitated using this process.

The actual lining process involves the inversion of a woven fabric liner with a plastic (PE) coating into the host pipe using air pressure. After the host pipe has been sufficiently cleaned, a solvent-free adhesive is uniformly impregnated into the fibers of the liner and then wound on to the Starline®2000 pressure drum. The drum is then attached, via transportation hoses to the host pipe and compressed air inverts the liner into the pipe where the adhesive impregnated fibers come into direct contact with prepared surface of the pipe. After the pipe section has been lined it remains under pressure overnight allowing the adhesive to properly cure. All existing services are tapped internally with our robotics package, thus eliminating the need to excavate at each service tee.

The technology, designed and patented by the Karl Weiss Group of Berlin, has successfully rehabilitated more than 300 miles of natural gas mains in the United States and Europe. PPM is the exclusive licensee authorized to perform this revolutionary technology in all of North America. Please see our "Starline®2000 SOP" in the MEDIA section for more information.
