Description

Ductile Iron Elbow Manufacturer,Ductile Iron Elbow Factory

　　Ductile iron elbows are made of magnesium or rare earth magnesium combined with gold spheroidizers added to molten iron before pouring to spheroidize graphite and reduce stress concentration, making the pipes have the advantages of high strength, high elongation, impact resistance, corrosion resistance, and good sealing. The inner wall is lined with cement mortar, which improves the pipeline water supply environment, increases water supply capacity, and reduces energy consumption. The pipe mouth adopts a flexible interface, and the pipe itself has a large elongation, which makes the pipe more flexible. In the buried pipeline, it can work together with the soil around the pipeline to improve the stress state of the pipeline, thereby improving the reliability of the pipeline network operation.

Advantages of Ductile Iron Elbows

　　1. Because ductile iron elbows use flexible joints, construction operations are more convenient, which can improve construction efficiency, improve construction conditions, and reduce construction costs. Moreover, most of the interfaces are connected by rubber rings, which are easy to operate, can shorten the construction period, and reduce construction costs.

　　2. Ductile iron elbows have the advantages of bearing high water supply pressure, resisting external loads and adapting to changes in geological conditions. The pipes have the advantages of high strength, good toughness, corrosion resistance, convenient installation of flexible interfaces, strong seismic resistance, and low labor intensity. They can be used in areas with poor geology and across highways. No additional processing of steel pipes is required. In addition, they have strong corrosion resistance and can be used in coastal and saline-alkali areas. They are widely used in underground pipeline projects. Large-scale pipeline installation projects can better reflect their advantages of convenient installation and low labor intensity.

　　3. Ductile iron elbows have good sealing performance and are not easy to leak, which can reduce the leakage rate of the pipeline network and reduce the daily maintenance costs of the pipeline network.
