Insituform RPP™ – Pressure Pipe
The structural solution for deteriorated pressure pipe

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 RPP ™ 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 RPP™ is the solution for your pressurized pipe system:
• Diameter ranges from 8 inches to 60 inches
• Restores structural integrity
• Suitable for rehabilitation of various pipe materials, including 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 45°
• Small site footprint required for installation
• Installed inside the existing pipe 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 RPP™ has a construction similar to that of standard Insituform® CIPP tubes. However, special fiberglass reinforcement is included to address specific service conditions found in pressure applications. The resin system for Insituform RPP™ is a vinyl ester.

Applications
Insituform RPP™ can be used on many different pressure systems:
• Sewage force mains
• Cooling water lines
• Fire water
• Process lines
