The main material of ductile iron pipe fittings is cast iron, and a certain amount of magnesium and manganese are added during the manufacturing process, which makes it have higher strength and corrosion resistance than ordinary cast iron. At the same time, ductile iron pipe fittings can also be flexibly connected with other pipes, flanges, valves and other parts and components, which is convenient for maintenance and replacement.

Ductile iron pipe fittings are a new type of pipeline material. Compared with traditional gray cast iron pipes, they have the following characteristics:
1. High strength
Ductile iron pipe fittings are spheroidized during the production process, and the spherical pattern is obvious and evenly distributed. Therefore, the strength of this material is significantly higher than that of ordinary gray cast iron, and it can withstand greater water pressure and external force impact.

2. Good corrosion resistance
The surface of ductile iron pipe fittings is galvanized and has good corrosion resistance. It is used in harsh environments such as sewage, wastewater, and seawater, and will not be corroded by liquids.

3. Good sealing
The interface seal of ductile iron pipe fittings uses rubber gaskets with excellent sealing performance. This material can ensure the stable sealing performance of the pipeline under conventional construction and use conditions, and there will be no water leakage.
4. Safe and reliable
Since ductile iron pipe fittings have the characteristics of high strength and good sealing, the number of pipeline connections can be reduced during design and manufacturing, which is conducive to the safe operation of the pipeline.
To sum up, ductile iron pipe fittings can be used in urban water supply, sewage, natural gas and other systems. They are a kind of pipeline material with excellent material properties, safety and reliability.
