Continuous inversion system

The Top Gun continuous inversion system from Perma-Liner Industries allows the CIPP liner tube to invert utilizing low air pressure. The liner inverts continuously without the need for above-ground water column towers, tall scaffold or the need for excess water in order to invert the CIPP liner. It allows the liner to invert easily and consistently without having to stop and start throughout the inversion installation. Most installs take less than 10 minutes, based on 500 feet of CIPP inversion from manhole to manhole. During the installation, no pressure is lost in the inverted liner. The liner is fully inflated at all times and held tightly against the existing pipe. Units range in different sizes to accommodate 6- to 36-inch diameters. 866/336-2568; www.perma-liner.com.

Lateral connection seals

The Interfit CIP lateral sealing system from Quadex/Interfit rehabilitates and seals lateral connections to lined sewer mains, eliminating infiltration and root intrusion. Depending on lateral defects/bends, the system extends from 1 to 20 inches into the lateral, sealing three critical problem areas — the annular space between a main liner and the host pipe, the lateral connection and the first joint. It includes a “full main wrap” (360 degrees) one-piece CIP fiberglass sock in the main that helps anchor the lateral portion of the sock. By using 25 to 30 psi inflation pressure, the nonshrinking resin attains superior migration into pipe defects, which yields superior mechanical adhesion and long-term performance. 870/688-7100; www.interfitusa.com.
