Cure-In-Place Pipe liners can be installed using several methods with three types of resin curing systems. CIPP liners can utilize steam, hot water, ultra-violet or ambient resin curing systems. Fast Pipe Lining does not provide or recommend the use ultra-violet or ambient curing resin systems. Fast Pipe Lining provides CIPP installation contractors with all types of liners to suit specific installation applications. Installation contractors play a critical role as they control the installation & cure of the CIPP liner.
Inversion Liners - The most commonly used CIPP liners are for installation by the inversion method. Inversion is the process where the liner is turned inside-out during the installation using a column of water or pressurized air; the liner walks itself through the host pipe. Inversion results with the exterior liner coating becoming the new interior pipe wall surface with the resin saturated felt pressed against the host pipe wall. The inversion process can be done using air pressure (a shooter or air inverter) or a water column (inversion water column). Water inversion was the original installation method used for over 25 years before air inversion method was developed.
Pull-in or Winch-in Place: The CIPP liner is pulled or winched through the host pipe into position. Liners used for this type installation require a second inner liner (double) coating or use of some type of inflation bladder. Inflation of a pull-in liner can be done by inverting a calibration tube through the liner when in position. This process can be done on a stand alone design (no host pipe needed), and can relines virtually any form of pipe material - clay, cast, metal, etc. The line is first cleaned and televised for liner measurements. The liner is wet-outted with resin best suited for the type of pipe and the location. Pull-in liners are typically used in short, large diameter pipes (storm culverts) or where inversion equipment cannot access installation site. Pull-in liners can be cured using hot water or steam. Pull-in liners can also have extra layers (thick) of felt that could not be inverted for installation. Pull-In-Place (PIP) pipelining has the ability to start and stop anywhere. We offer the Pulled-In-Place pipelining services for pipelines from 4" - 8" in diameter in less than a day and in most cases less than 5 hours. The versatility of this system allows lining 22’s, 45’s, sweeping 90’s bends and vertical stacks with ease, while stopping and starting anywhere in the line. One of the benefits of Pulled-In-Place pipe repairs is that can bridge missing sections of pipes. We string a line from the first access point to the second. Attach winch cable to the leading edge of liner’s pull end, then attach the air hose and second winch cable to the back air end and pull the liner into place (Winch-In-Place). There is no digging up floors, landscaping, or tearing up walls. We also have 4" - 6" transitions without changing the structural properties of the liner.
Fast Pipe Lining provides ready to install CIPP liners using several different catalyzed resin systems for use with steam or hot water curing systems, all which conform to ASTM Standards.
As part of the wet-out process, sample material from CIPP liners is used to prepare flat plate test samples. Samples are compressed between two pieces of metal to the specified thickness then wrapped in polyurethane. Test samples are shipped with the related CIPP liner to the installation site where the sample is cured as part of the liner installation process. To cure flat plate samples, samples can be submersed in the inversion water column or placed with the CIPP liner for steam curing. For hoop test samples, Fast Pipe Liner can ship pre-cut plastic pipe sections for sample making at the time of installation, a time saving process for installation crews.
