LAS VEGAS — Pipe Restoration Technologies LLC (PRT), makers of the ePIPE system for restoring pipes in-place, announced that it has been granted its 12th United States patent, No. 8887660, for barrier coating corrosion control methods and systems.

This patent covers methods and process steps for mapping, cleaning, and providing barrier coatings to the interior walls of piping systems. Pipes can be cleaned in one single pass by dry particulates forced by air, and the pipes coated in one single pass. Pipes can be protected from water corrosion and lead leaching, improving water quality, water flow, and sealing leaks in-place. Pipes from ½ inch up to 6 inches are treatable using the ePIPE system. Potable water lines, natural gas lines, HVAC, drains, and fire sprinkler systems in homes, apartments, condominiums, hotels, office towers, and schools can be treated.
