ePIPE Patents

We are the only company with over 40 US and International patents for small diameter pipe restoration. The ePIPE process is covered by US patents #7160574, #7517409, #8033242, #7858149, #8206783, #8343579, #8354140, #8399813, #8524320 #8696823, #8795768, #8887660, #8895905, #9273815, #9352357, #9446429, #9555453, #9611973, #9724730, #9744561, #9764354, #9889469, #9889470, #10076769, and #10076770 . These patents focus on ePIPE technology that provides an internal barrier coating in pipes while the pipes remain in-place.

The ePIPE patents (other patents pending) provide distinct improvements over other similar technologies.

Provide for the use of a vacuum in the process which assists in more efficient evacuation of debris left in the pipe during the cleaning process and provides for a less aggressive, more efficient method of cleaning the piping system.

Cover our methods for providing an internal coating and sealing leaks in the existing piping.

Cover the in-place coating of metallic pipes, including lead, copper and steel pipes, reducing lead leaching from lead pipes and other in-line lead contributors, such as lead solder from leaching into the drinking water supply. Using the ePIPE process, lead levels are reduced to well below the World Health Organization’s (WHO) cut-off guidelines for lead, at 10ppb.
