In industrial projects, the selection of materials is of vital importance. Ductile iron pipes have become the preferred choice for many projects due to their outstanding performance. It has extremely strong pressure resistance and can effectively meet the usage requirements in complex environments. Pipes made of this material perform well when transporting water and gas and are less likely to have leakage problems. Meanwhile, it also has good corrosion resistance and a longer service life. This is a very reliable choice for scenarios that require long-term stable operation. Ductile iron is a kind of gray cast iron with excellent mechanical properties. Generally, before pouring, a small amount of spheroidizing agent (usually magnesium, rare earth magnesium alloy or cerium-containing rare earth alloy) and inoculant (usually ferrosilicon) are added to the molten iron to make the molten iron solidify and form spherical graphite.
