What does the acronym CIPP stand for?

The acronym CIPP stands for Cured-In-Place Pipe. This refers to a trenchless rehabilitation method used primarily for repairing existing pipelines, particularly in underground sewer systems. The CIPP process involves inserting a resin-saturated felt tube into the damaged pipe. Once in place, the tube is cured, usually by applying heat or ultraviolet light, which hardens the resin and forms a new, durable pipe within the old pipe. CIPP is favored because it minimizes disruption to the surface above the pipelines, preserves the original pipe's structural integrity, and is effective in extending the life of aging infrastructure.

While the other options mention various pipe-related terms, they do not align with the trenchless technology methods used in rehabilitation efforts like those of CIPP.
