Excerpt: . . . DEFINITIONS Cured-in-place pipe ( CIPP ) - a hollow cylinder consisting of a polyester and or glass reinforced plastic fabric tube with cured thermosetting resin. The CIPP is formed within an existing pipe and takes the shape of the pipe. Folded pipe - pipe that has been manufactured and calibrated round, then subsequently cooled and deformed into a folded shape for insertion into the existing pipe. Force main - a pipe that transports raw sewerage and operates under pressure. Formed pipe - a folded pipe that has been inserted into an existing pipe and expanded with steam heat and pressure, and, if required by the manufacturer, with a squeegee device or pig to provide a close fit to the existing pipe. Hydrostatic design basis ( HDB ) - a long-term hoop tensile stress when applied to the pipe or liner continuously for the specified time period ( usually 100, 000 or 438, 000 hours ) will result in failure of the pipe or liner. Partially deteriorated pipe - the existing pipe can support the soil and surcharge loads throughout the design life of the rehabilitated pipe and the soil adjacent to the existing pipe must provide adequate side support. Fully deteriorated pipe - the existing pipe is not structurally sound and cannot support soil and live loads or is expected to reach this condition over the design life of the rehabilitated pipe. This condition is evident when sections of the existing pipe are missing, the existing pipe has lost its original shape, or the existing pipe has corroded due to the effects of the fluid, atmosphere, or soil.
