Ductile iron cement lined - Ductile iron pipe and fittings

The cement mortar lining is an active coating. It is not merely a barrier coating but provides chemical protection through the phenomenon of passivation. When the pipe is filled, the mortar gradually absorbs water, which becomes enriched in alkaline substances ; it is therefore non-corrosive when it reaches the proximity of the metal wall.
