Process 2. Cured In Place Pipe (CIPP): This process will be used on Division B and <br /> Division C work which has pipe sizes ranging between 4 feet in diameter to 2 feet <br /> in diameter. The process involves inflating a felt tube soaked with resin into the <br /> sewer pipe. Once the felt tube has been inflated throughout the length of pipe, <br /> heated water or steam fills the tube and is kept at a high temperature until the <br /> resin cures and hardens to form a new pipe inside of the deteriorated pipe. <br /> Figure 9. Heat curing of felt tube liner. Figure 10. Inserting the liner into the pipe. <br /> The CIPP process has been used with good success by the City for years in many <br /> locations. Figures 9 and 10 above show cured-in-place lining installation work <br /> completed on past City projects. <br /> Page 110 <br />
