A California pipe restoration company has gained a patent for a new technology that provides an internal barrier coating and seals leaks in water and gas pipes while the pipes remain in place.
The patent by Pipe Restoration Technologies LLC (PRT) covers pipes used to carry potable water, natural gas, fire sprinkler systems and drains, the company says. PRT is the parent company of ACE DuraFlo Systems LLC.
Restoring Pipes in Place
The patent is focused on what the company calls “ePIPE technology.” The process involves restoring pipes in place with an application of an epoxy barrier coating, resulting in a restored, epoxy-lined piping system without conventional repair and repiping.
“Our research and development team are proud of this accomplishment,” said Larry Gillanders, CEO of ACE DuraFlo Systems. “Focusing on commercializing smart innovative green solutions is part of our ‘Made in America’ philosophy. This patent, added to our existing portfolio of patents and IP, supports us in this pursuit.”
Innovation Nomination
The company said its ePIPE team was recently nominated for the National Medal of Technology and Innovation, which is awarded by the U.S. Patent and Trademark Office.
Pipe Restoration Technologies is a spinoff of a contracting firm, Western Restoration Services, that was established in 1980.
According to the company’s website, the owners formed PRT to develop their own coating material and process for pressure injection of epoxy coating inside pipe systems.
The company says its process is appropriate for manufacturing facilities, waste treatment plants and nuclear power plant cooling systems and can be used on copper, galvanized steel, cast iron and stainless steel pipes.
