Scope of application
Ductile iron pipe is a kind of cast iron pipe, which is used as buried water supply pipe.
advantage
It is cheaper than steel pipe, easy to manufacture, and has strong corrosion resistance; The disadvantages are brittle and heavy. There are data showing that there are pipes between DN40 and DN80, but only specifications above DN80 are listed in the design manual. There is no change in pipe wall thickness due to nominal pressure, and it is unnecessary to specify the nominal pressure level.
