4. Cast iron pipe for water supply
"Water supply cast iron pipes are pipes made of cast iron above grade 18, added with nodularizing agent, and centrifugally cast through a centrifugal ductile iron machine at high speed. Ductile iron pipes have the essence of iron and the properties of steel, excellent corrosion resistance, good ductility, good sealing effect, and are easy to install. They are mainly used for water supply, gas transmission, and oil transportation in municipal and industrial and mining enterprises.".
