LAS VEGAS — Pipe Restoration Technologies LLC, makers of the ePIPE in-place pipe restoration product line, announced that it has been granted its 10th United States patent, No. 8696823, which covers methods used in abrasive cleaning inside small diameter pipes, 2 inches ID and smaller, such as water supply pipes.

This patent focuses on methods where intermittent bursts of abrasive particles are injected into the piping system for cleaning the interior walls of the pipes reducing burrs and interior lips which can cause unnecessary and unwanted erosion inside the pipe. Such erosion can lead to early wear and potential leaks such as those commonly referred to as slab leaks, when the leak occurs under a concrete slab. This patented process gives the operator greater control and efficiencies when compared to alternative methods.

The patented ePIPE process involves restoring pipes in-place, with an application of an epoxy barrier coating resulting in a restored epoxy-lined piping system. The process provides a solution for pinhole leaks, corrosion control, and prevention of lead leaching from pipes. For more information, visit
