The AMEX 2000 gas main lining process by Miller Pipeline Corp was chosen as the most feasible method of repairing a leak in a critical high pressure feed line located right in the middle of a busy intersection in Riverside, OH. The method allowed services to be installed without any need for special fittings or equipment while its polyurethane lining produces a negligible reduction of the pipe's inside diameter and also bonds fully to the inner surface of the pipe. The lining process enabled the repair of the leaking gas mains and minimized public inconvenience along the way.See the full content of this document

Utility uses gas main liner to rehab high pressure pipeline.
Repairing leaking gas mains, reducing public inconvenience during the process...and doing it all in the most cost-efficient manner are three objectives that don't always coincide for utility companies. But a recent project for Dayton Power & Light Company (DP&L) utilized a trenchless pipeline rehabilitation method and proved that all of these goals can be achieved.
In late July 1997, DP&L crews detected a leak in a critical high pressure feed line located in Riverside, OH, a suburb of Dayton. Unfortunately, the leaking area was located under the middle of a busy intersection. The main is a 16-inch diameter steel pipeline with an MAOP of 110 PSI. Originally i...See the full content of this document
