Ductile iron pipe is made of magnesium or rare earth magnesium combined with golden spheroidizing agent added to hot iron before pouring, so that the graphite spheroidization, stress concentration reduction, so that the pipe has the advantages of high strength, high elongation, impact resistance, corrosion resistance, good sealing and so on; The inner wall is lined with cement mortar, which improves the water transport environment, increases the water supply capacity and reduces the energy consumption. The pipe mouth adopts a flexible interface, and the pipe itself has a large elongation, so that the pipe flexibility is good, in the buried pipe can work with the soil around the pipe, improve the force state of the pipe, thus improving the reliability of the pipe network operation. Therefore, the water supply industry usually uses ductile iron pipe as the main component in our country.

1. Because ductile iron pipe fittings adopt flexible joints, the construction operation is more convenient, can improve the construction efficiency, improve the construction conditions, reduce the construction cost, and most of the interface adopts rubber ring connection, easy operation, can shorten the construction period, reduce the construction cost.

2. Ductile iron pipe fittings have the advantages of high water supply pressure, resistance to external load and adaptation to the change of geological conditions. The pipe has the advantages of high strength, good toughness, corrosion resistance, flexible interface convenient installation, strong seismic resistance and low labor intensity. In addition to strong corrosion resistance, can be applied to coastal and saline-alkali zone. It is widely used in underground pipeline engineering. Large-scale pipeline installation projects can reflect its advantages of convenient installation and low labor intensity.

3. Ductile iron pipe fitting 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.
