Insituform® PPL – Pressure Pipe Liner
The trenchless solution to pressure pipe leakage and corrosion
 Your damaged pressure pipe system needs a solution that is specially designed to withstand the operating pressure and thermal stresses during your system’s operation. Insituform PPL® is an advanced, proven and non-disruptive technology that will extend the useful life of deteriorated and leaking pressure pipes. And because it requires limited access and is installed by experienced Insituform® safety-certified teams, there is minimal disruption to system or plant operations.
Insituform PPL® is a custom-engineered, cured-in-place pipe (CIPP) product designed to eliminate leakage and prevent internal corrosion and/or erosion in structurally sound pressure pipe. Insituform PPL® is designed with the flexibility to expand up to and transfer internal pressure loading to the host pipe while maintaining the ability to span any small holes, pits or open joints that may exist in the host pipe. The Insituform PPL® design assumes that the host pipe is currently structurally sound and will continue to carry the internal pressure loading for the life of the piping system.
 Insituform PPL® is the solution for your pressurized pipe system:
• Diameter ranges from 8 inches to 60 inches
• Suitable for cast/ductile iron, steel, asbestos cement, RCP and thermoplastic pipes
• Thin wall and close fit minimizes reduction in flow cross section
• Flexibility to negotiate horizontal and vertical bends up to 90°
• Small site footprint required for installation
• Installed inside the existing main so there is no risk of damage or disturbance to adjacent utilities or infrastructure
• Trenchless installation reduces traffic and commercial disruption, site noise, pollution and safety concerns as well as the need for imported backfill and pavement reinstatement
• Rapid installation reduces the duration of the project along with the associated costs and impact
Structure
Insituform PPL® has a construction similar to that of standard Insituform® CIPP tubes. However, special glass reinforcement is included to address specific service conditions found in pressure applications. The resin system for Insituform PPL® is either a vinyl ester or an epoxy, depending on the application. For drinking water applications, a special epoxy resin system is available for use.
Applications
Insituform PPL® can be used on many different pressure systems:
• Cooling water lines
• Fire water
• Process lines
• Sewage force main systems
• Drinking water systems
