Nu Drain

NuDrain 4c Nu Drain

Nu Drain, NuFlow’s leading structural lining technology, enhances the structural strength of the host pipe and acts as a stand-alone pipe within a pipe.

NuDrain can be installed in pipeline with diameters from 1 1/2 inches to 12 inches and larger. NuDrain is best used in two primary applications: the ‘pull-in-place’ (PIP) method and the ’inversion’ method.

Small Diameter Pipe Lining

NuFlow’s Small Diameter Reline System can reline complete inside-infrastructure systems. By using NuFlow’s tools, technicians can reinstate lined laterals. Branch lines can then be lined to the stack quickly and easily.

NuFlow’s small diameter pipe lining gives you the benefit of being able to line complete systems right from the 3″ (65mm) or 4″ (80mm) stack down to the 1.5″ branch lines.

Lateral Lining

NuFlow’s Lateral Lining System is used to remotely repair full sections of damaged pipe or even sections anywhere in the lateral. NuFlow’s lateral lining products allow technicians to remotely fix damaged pipe anywhere in the line. Our products are user friendly and easy to install. All of our products can be installed via the clean out.

The PIP (Pull-in-Place) Advantage

PIP application starts with a felt liner soaked in epoxy and pulled into place through the system. When the felt liner is in place, a rubber bladder is expanded internally using air pressure to help the epoxy adhere to the interior of the pipe.

A pull-in-place application can be used through 45° and 90° angles whereas inversion applications cannot. Pull-in-place application also allows you to line certain pipe sections as opposed to the entire length.

PIP vs. Inversion method

The other most common method of CIPP lining is Inversion, which is a less innovative, more traditional technique, where the liner rolls out from the point of entry as it is filled with water, air or steam. Once cured-in-place, the end and connection points are trimmed to allow for flow.

Millions of linear feet of drain and lines have been saved using the pull-in-place process. Whenever possible, we work to eliminate waste and unnecessary use or destruction of resources.
