Ductile ,iron, pipe manufacturers began lining pipe with cement as early as the 1920s. In a water application, the cement lining is applied to prevent electrochemical corrosion, also known as tuberculation, from occurring on the surface of the pipe. The cement lining also increases the pH at the surface to help mitigate tuberculation.
