Let’s consider how a ductile iron pipe is produced. The most common process is producing ductile iron pipe fittings, which starts with the melting of high grade cast iron and alloying materials, The molten metallic materials are poured into prepared molds to manufacture pipe sections. In order to achieve ductility and strength, the manufactured pipes undergo a controlled cooling process. The developed pipe characteristics allow the folded pipe to withstand immense pressure and stress meaning this type of pipe is ideal for projects that involve critical growth and development fields. With Shandong Hongzheng Metal Products Co. Ltd. we are able to use modern technology and tightening control over the quality of production practice to make ductile iron pipes that comform to international standards for all projects purposes.
