Cement Mortor Lined Ductile iron pipe has perfect anti -corrosion property, according to the record, there were cast iron pipelines and fittings layed over 300 years ago still in use. And countless cases show that ductile iron pipes and fittings have more than 100 years pf serivice life. As regard to the using of ductile iron pipes . The history is over 30 years. But ductile cast iron is nearly identical to gray cast iron in chemical composition.It also contains far more silicon,carbon and other elements than steel.The resistance of ductile cast iron to corrosion is also similar to that of gray cast iron. This has been demonstrated in use and proved empirically.
