(CIPP) Lining

CIPP Lining consists of wetting out a felt lining that is manufactured to fit the host pipe with a two part PipeGuard™ TR series system, once fully saturated the liner is pulled into place or inverted with air or water through the host pipe. (Ideal installation: 50 – 150 m straight sections with up to 1x bend < 45°, ⌀'s ranging from 100 – 800 mm). Once the liner has been fully inverted throughout the pipe section, either steam or water (> 80 °C) is circulated throughout the liner to cure the resin impregnated lining. After determining the liner has fully cured (2 – 15 hrs. depending on ⌀) the liner ends are trimmed and robotic tooling is used to re-open lateral connections prior to reinstatement.

Ideal Site Conditions for (CIPP) Installation:
  • Straight sections mh to mh with (1x bend < 45°)
  • Smaller ⌀'s ranging from (100 – 800 mm)
  • Gravity piping systems (non pressure applications)
  • High level of infiltration, (eliminates robotic patching)
  • Site limitations permit longer downtime for installation
  • No space constraints, (large equipment footprint)

    PipeGuard™ Epoxy Systems

    PipeGuard™ TR series formulations are two part resin systems that have been designed to optimize the (CIPP) installation process in humid and wet conditions. The cured system results in a low shrink lining with consistent physical properties that exceed ASTM F1216. The PipeGuard™ TR epoxy, vinyl and polyester resins reaction rate can be varied to provide custom processing times based on site constraints for lining installation.
