Insitu<strong>for</strong>m RPP is a custom engineered CIPP product designed to restore the<br />
structural integrity to distressed pressure pipes and prevent internal corrosion<br />
and/or erosion. It is a structural renewal product that does not rely upon the host<br />
pipe. The CIPP tube has a similar construction to standard Insitu<strong>for</strong>m CIPP<br />
tubes, with special glass rein<strong>for</strong>cement included to handle pressure applications.<br />
Resin used is vinyl ester.<br />
<strong>Main</strong> Benefits • Provides a structural renewal.<br />
Claimed • Spans over small holes, gaps or open joints.<br />
• Extends life <strong>of</strong> a deteriorated or leaking pressure pipe.<br />
• Minimal disruption as installed inside existing main, trenchlessly.<br />
• Smooth interior surface.<br />
• Stops internal corrosion.<br />
<strong>Main</strong> Limitations<br />
Cited<br />
Applicability<br />
(Underline those that<br />
• Can be installed in line with bends up to 45 o .<br />
• Interior must be very clean, with no protrusions.<br />
• Shut down system or by-pass pump during insertion and cure.<br />
• Incomplete long-term pressure regression tests on cured RPP liner available<br />
<strong>for</strong> confirmation <strong>of</strong> design values recommended <strong>for</strong> long-term tensile<br />
strength in pressure design (Did not achieve the correct number <strong>of</strong> bursts<br />
during the log time frames to meet the ASTM data requirement).<br />
