What is CIPP Liner?
The aging and damage of underground drainage pipeline is a serious problem for the city. It takes a lot of time and high labor cost to repair with traditional excavation, and it is inconvenient. We can choose a smarter way: trenchless repair.
Cured-in-Place-Pipe (CIPP) lining is a method of trenchless rehabilitation and restoration used in the repair of existing pipes. CIPP lining uses a textile liner tube and a liquid resin.
The process begins with the wet-out stage. During this stage, the textile liner is impregnated with the resin mixture, an epoxy base with a pre-determined hardener.
Next, the liner is inverted into the pipe with air pressure. The resin will now be on the outside of the liner against the existing host pipe wall.
After inversion, a calibration tube is inverted inside the liner which can then be ambient, hot water, or steam cured. During this period, the curing agent activates the resin causing it to harden, creating a fitted, smooth, and corrosion-resistant new pipe wall.
If necessary, a robotic cutting device will be inserted into the newly lined pipe to reinstate any branch line connections.
