 U-Liner
is a high density polyethylene (HDPE) pipe, deformed during
manufacturing into a "U" shape approximately one-half the
diameter of the host pipe. At the installation site, U-Liner
is winched into the damaged host pipe and then reformed to
securely fit the shape of the host pipe. The end result is a
structurally sound "pipe within a pipe" that offers a true "jointless"
installation. Applications 4"-15"
U-Liner can be supplied to a wide
variety of Residential and Industrial applications
including:
- Sanitary sewer and waste
pipelines
- Oilfield and containment
pipelines
- Gas transmission pipelines
- Industrial process
pipelines
- Nuclear facility cooling
systems
- Force mains and slurry
pipelines
- Potable water, drainage
and irrigation pipelines
- High-rise building
utilities
- Electrical conduits and
marine vessel pipes
The U-Liner Process:
 Prior
to any installation, U-Liner is specially designed and
manufactured for your project. Made in continuous lengths,
the pipe is d eformed
and coiled onto a reel, for easy transport. Once on the job
site, the damaged host pipe is flushed to remove any
blockage or debris. After a closed circuit TV camera
inspects the line, U-Liner is inserted through the upstream
manhole. A patented heat/pressure method is used to reform
the U-Liner to fit the shape of the host pipe. Service
connections are then restored without excavation by a remote
controlled lateral cutter. The entire process is
accomplished quickly, with little or no disruption. The work
is completed within a matter of hours, not in days; as is
usually the case with traditional dig and replace methods.
