Corrosion Protection for Concrete Pressure Pipe

Abstract Water and wastewater pipelines represent significant investments by owners and disruptions in these pipelines create inconvenience and safety concerns for users. Therefore, long service life is essential for the pipeline materials. Concrete pressure pipe is widely used for conveyance of water and wastewater and has been successfully used for more than 80 years. This paper discusses the corrosion protection methods used for concrete pressure pipe to ensure long service life. It will cover both the inherent corrosion control properties of concrete pressure pipe and supplemental corrosion control methods used in extremely aggressive environments.
