1. Because ductile iron pipes adopt flexible joints, the construction operation is more convenient, which can improve the construction efficiency and reduce the construction cost. Moreover, most of the interfaces are connected by rubber rings, which is easy to operate, can shorten the construction period and reduce the construction cost.
2. Ductile iron pipes can bear high water supply pressure, resist external loads and adapt to changes in geological conditions. The pipe has the advantages of good toughness, convenient installation of flexible interface, low labor intensity, etc. It can be used in sections with poor geology and across highways, without additional processing of steel pipes. In addition, it has strong corrosion resistance and can be applied to coastal and saline-alkali areas. It is currently widely used in underground pipeline engineering. Large-scale pipeline installation project can better reflect its advantages of convenient installation and low labor intensity.
3. Ductile iron pipe has good sealing performance and is not easy to leak, which can reduce the leakage rate of pipe network and reduce the daily maintenance cost of pipe network.
