Ductile iron pipe pricing class c K7 K9 

Ductile iron pipe is a kind of cast iron pipe known for strength, durability and flexibility. It is made by adding small amounts of magnesium to molten iron, which alters the metal's molecular structure and makes it more malleable. This allows ductile iron pipes to be bent and molded without breaking, making them ideal for groundwater and sewer systems. Ductile iron pipes are also resistant to corrosion and can be used for decades with minimal maintenance. It is commonly used in municipal water supply systems, wastewater treatment plants, and industrial applications.
