Ductile Iron Pipes

Outer coating of ductile iron pipes

The external material of a pipe is covered with protective zinc metal and final protection coating according to ISO 8179

Internal ductile iron pipe lining

The inner surface of the pipe may have cement mortar lining (CML). Thickness and properties are according to ISO 4179.

The unique properties of the cement mortar lining lie in both passive and active protective effect.

in case of agressive soil or transported liquid other types of coatings can be used. It is recommended to consult the manufacturer on their application.
