The Ductile Iron Pipe Production Phases | Shandong Hongzheng Metal Products Co., Ltd.

The manufacturing process of ductile iron pipes is a complex and precise procedure that involves several key steps to ensure the production of high-quality, durable products. The process begins with the melting of raw materials, including iron, carbon, and silicon, in a furnace to form molten iron. This molten iron is then treated with a nodulizing agent, such as magnesium, to transform the graphite in the iron from a flaky structure to a spheroidal shape, which gives ductile iron its unique mechanical properties. After nodulization, the molten iron is poured into centrifugal casting machines, where it is formed into pipes by rotating the mold at high speeds. This centrifugal casting process ensures a uniform wall thickness and dense microstructure, resulting in pipes with excellent strength and durability. Once the pipes are formed, they undergo a series of heat treatment processes to improve their mechanical properties, such as annealing to reduce internal stress and enhance ductility. After heat treatment, the pipes are inspected for dimensional accuracy, surface quality, and structural integrity. Finally, they are coated with a protective layer, such as zinc or epoxy, to enhance their corrosion resistance. At Shandong Hongzheng Metal Products Co., Ltd., we utilize advanced manufacturing equipment and strict quality control measures to ensure that our ductile iron pipes meet the highest industry standards. Our experienced team of professionals oversees every step of the manufacturing process to ensure that each pipe is produced to the highest quality standards.
