LINER: The most basic and very simplest liner description: "CIPP liners are constructed of a tubular layer(s) of non-woven polyester felt with an exterior polyurethane coating. A calculated amount of catalyzed thermosetting resin mixture is impregnated into the felt during a process called Wet-Out. The felt acts as both a resin carrier and adds flexible strength to the finished liner. Upon completion of the Wet-Out, the CIPP liner is transported to the installation site within a refrigerated truck. At the installation site, the CIPP liner is positioned within the host pipe either by inversion (air or water) or winched into place. Once in position, the CIPP liner is inflated by air pressure or by a water column to press the material against the host pipe wall. When fully inflated, steam or hot water is circulated within the liner to start the thermosetting resin to cure or harden. After the cure has completed, the liner is slowly cooled to prevent shrinkage."
CIPP liners can be designed & manufactured in many ways depending individual project criteria. We offer Polyurethane and Polypropylene coated liners. Fast Pipe Lining provides liners for all types of design and application requirements.
A Proven Trenchless Technology - following the guidelines set forth by ASTM Standards (50 year design life) , proper installation of a CIPP liner within a host pipe results in a "New Pipe Within A Pipe". CIPP liners are designed to be independently structurally strong, not relying on the host pipe for any structural strength contribution. Installation of a CIPP liner minimally reduces the diameter of the host pipe, but the diameter loss is offset by increased flow characteristics of the liner surface material. ASTM sets the Standards for manufacturing & use all types of pipes.
Cured-In-Place Pipe can remedy numerous pipe defects. Root infiltration is virtually eliminated since CIPP liners are "one piece" extending from manhole to manhole to manhole. Single piece liners can reduce or eliminate inflow & infiltration problems. CIPP liners can bridge offset pipe joints or gaps where sections of pipe are missing.
What Size Pipes Can Be Lined: The growth of the CIPP pipe lining industry has been phenomenal in the past 10 years. Pipes from 3" to 96" diameters are successfully installed on a daily basis. Plumber & drain cleaners now install CIPP liners within house laterals or pipes located under the floors of buildings to avoid costly excavations. CIPP liners can be installed in round, oval, egg-shaped or square box brick sewers. In the large pipe diameter market, single installations can range up to 1500 linear feet. Installing CIPP liners has become commonplace. Limitations on installations are slowed by the time requirements to reinstate lateral service connection and setup of bypass pumping systems. Size & weight of an individual CIPP liners have a direct effect on installations. CIPP liners are limited to DOT transport regulations. For large CIPP liners, over the hole Wet-Out (resin impregnation of the CIPP liner bag) can be performed. We also offer pipe size transitions.
FAST Pipe Liners are CIPP liners that are fabricated & installed to meet specified pipe wall thickness.
