What quota can be used for the installation of DN300 ductile iron pipes?
Ductile iron is a kind of high strength cast iron material developed in 50s twentieth Century, its comprehensive performance is close to the steel, it is based on its excellent performance, has been successfully used in casting complex stress, strength, toughness and wear resistance requirements of the higher parts. Nodular cast iron has developed rapidly to be second only to grey cast iron and widely used as cast iron material. The so-called "iron instead of steel", mainly refers to ductile iron.
Moreover, the ball tube is generally 5.5 meters long or 6 meters, if the length of the bridge is too long, to use the casing, the casing must also be fixed, and so on.
Ductile iron quota, to see what works, such as the use of ductile cast iron bridge, to see the river length, through traffic, perennial water level to determine the ductile iron pipe length, diameter and number;
