Cement–Mortar Lining for Ductile-Iron Pipe and Fittings
Cement–mortar linings prevent tuberculation by creating a high pH at the pipe wall and ultimately by providing a physical barrier to the water. Cement–mortar linings are also smooth, which results in high flow coefficients. In 1922, the first cement–mortar-lined cast-iron pipe was installed in the water distribution system of Charleston, S.C.
