Description of Main
Features
Main Benefits
Claimed
Duraliner is a patented, fully structural pipe rehabilitation system. The piping
system can handle a wide range of system operating pressures and restore or
improve the flow capacity of the host pipe. Duraliner PVC provides a designlife
of 100+ years. The end result is a brand new pipe within the existing pipe.
• It meets system operating pressures.
• Fully structural “stand alone” system.
• It is resistant to water disinfectant induced oxidation and resistant to
hydrocarbon permeation.

II. Technology Parameters
Rehabilitation and Replacement
Service Connections • Duraliner is tapped with standard fittings and procedures.
• Duraliner easily connects with standard fittings and valves.
• Most common applications have Duraliner expanded to ductile iron (DI)
outside diameters (OD), making standard PVC gasketed fittings compatible.
• Duraliner may be tapped with the same tapping saddles used on
conventional PVC.
• When tapping Duraliner one should refer to the Uni-Bell PVC Pipe
Association's guidance for tapping PVC.
