How does the cement lining protect the pipe?
The internal cement mortar lining provides protection to the pipeline in two ways. First, it is a cement pipe within a steel pipe, and second, by creating a Zone of Alkalinity. This zone between the cement lining and the pipe wall, neutralizes the corrosive properties of the liquid medium and blocks corrosion of the pipe wall. In effect, the Zone of Alkalinity serves as a second layer of defense against internal corrosion. Unlike other types of internal linings, which allow pipe corrosion to spread down the line once they are chipped or damaged in any spot, the cement lining prevents corrosion from spreading along the pipe wall.
