Wall Thickness
Ductile Iron pipes have been classified as K7, K8, K9, K10 etc depending on
service conditions and wall thickness.
Nominal Diameter, External Diameter and Wall Thickness these are the dimensions of Ductile iron
Advantages of Ductile Iron Pipe
Strongest pipe high tensile and beam strength
Can endure high working pressure
Speedy laying, installation due to push-on jointing system
Centrifugally applied cement mortar lining offers a smooth surface and gives a
higher Hazen William’s value of 140
Lesser friction loss offers impressive energy savings
