This document summarizes the 3" and 4" pipelining project at Sequoia Hospital involving Nu Flow America. The process included camera inspection and cleaning of pipes, preparing a felt liner by saturating it with epoxy, and installing the liner into the pipes by pushing it from one access point and pulling it from the other while inflating an air bladder to form it to the pipe. The finished product creates a schedule 40 pipe inside the existing pipe with a life expectancy of over 75 years.
