For municipalities and industries that can’t afford the time and expense to dig up damaged pipes, there is a fast, high quality solution. The EX Method from Miller Pipeline. This trenchless installation of EX Pipe causes no disruption to the natural environment or to urban residential areas. EX Pipe is high strength, un-plasticized PVC manufactured under strict quality procedures using odorless, environmentally-safe materials. EX Pipe is expanded-in-place, not cured-in-place, so factory-controlled, ASTM F-1504 uniform quality is assured for every installation. The high strength and flexibility of EX Pipe allow it to withstand ground movement and failure of the host pipe without effecting its integrity. The EX Pipe material is softened with heat and continuously inserted into existing manholes for access. After insertion, the pipe is then expanded, approximately 10%, to fit tightly within the host pipe, resulting in a continuous, jointless pipe-within-a-pipe without ribs or folds. A new EX Pipe can be installed in a fraction of the time required by other methods. When work is completed, the new pipe exhibits maximum durability and corrosion resistance, and in most cases, no loss of flow capacity.
